Dexcom G7 Positive Reviews

Useful but frustratingThe app itself is works well for me and I like the features it does have. My issues with it are the features it lacks, starting with dark mode. Why, after all these years, is there no support for dark mode?! When I wake up in the middle of the night to deal with an alert it makes it that much harder to see, process, and understand what the app is trying to tell me when I'm being blinded by the glaring brightness of this solid white screen. I already set my screen brightness at its lowest level at night and it's still not enough. I don't have this issue with the Tandem t:connect app when I need to use my pump, because they actually implemented a dark mode. My next issue is with the watch app and how few watch faces the G7 complication even supports. I just updated my watch to watchOS 11 and the photo watch face, which I had previously been using the G7 complication with just fine, no longer shows the G7 as an option. Why????? Why does there seem to be so little support for developing this app? Why does it take so long to get anything updated in this app or to add any features? If the issue isn't Dexcom and instead it's healthcare regulations that are slowing everything down, why can't Dexcom be more transparent and open about it?.Eric536C75747AVersion: 2.4.0

Pros and ConsRecently switched to the g7, and I had high hopes. Certain things are much improved, like the urgent low alarm sound (the g6 urgent low sounded like an air raid siren, so this g7 chime sound is much less jarring). I use the Tandem pump and t:connect app, and I don’t want to have alerts/notifications for the same thing (highs or lows) on two different apps. For the most part I’m able to disable the notifications here since I prefer the tandem notifications, but the constant pop-ups that notifications are disabled when opening the g7 app are quite annoying. One bug I’ve not been able to deal with that urgently needs a fix is that the app freezes when I go into the Connections menu, and it doesn’t respond to any of the options on that screen or clicking into any of the other sections of the app either. So in my experience this part of the app is useless, and I have to close the app and restart to regain functionality. I’m not able to end a sensor when it starts losing accuracy near the end of the sensor life, and I’m forced to wait for the sensor to expire so I can start a new one. Other than those things, I like the interface and having the Clarity integration into the main Glucose screen of the app..MFJ_007Version: 1.11.0

Okay When it WorksI had to switch to the G7 about a month and a half ago after becoming pregnant due to the G6 not being approved for pregnancy. I have used the Dexcom G6 for over 3 years. I don’t have many signal or connectivity issues, but I feel like the notifications are all over the place. I’ll get a push notification that I’m 61 and dropping but when I open the app it’s saying 45, so it seems to be behind sometimes with the notifications. Sometimes they’re loud and sometimes they’re quiet and sometimes I don’t get notified at all. The widget doesn’t display a number most of the time which defeats the purpose. I enjoy having the clarity summary at the bottom and also like that there’s an option for notes now. This is about the product, not the app. The sensor patch and overpatch are very flimsy and not as secure as the G6. I find the G7 is peeling much quicker, and when I go to remove it the overpatch is very stretchy/thin and difficult to remove in one piece and rips into little pieces. I really want to like the G7, but I miss the physical structure of the G6 and the consistent notifications..KeckmcVersion: 1.9.2

The features are an upgrade from G6.I’ve been using G7 for about six months now upgrading from the G6. It works great with my pump PDM phone and direct watch. I’ve had not had any issues.. I love that you can put it on 30 minutes before the other one expires and keep it on for an additional 12 hours before you have to change it. You have some pretty detailed settings in the alert section of the app as well, which is nice. Something that is not very customizable is the direct watch settings, in fact, there are absolutely none. I would love to see that in the phone app to where you can mirror your phone settings for alerts on your watch. For example, if you are having a high blood sugar that is refusing to come down your watch goes off every 15 minutes even if you’ve hit the OK or dismiss buttons on your watch and or phone. I have my alerts on my phone set up to where they don’t continually go off unless it’s been high for an hour. If you are sleeping, this is not very friendly. So mirroring settings from the phone to the watch would be helpful!.Type1 of a kindVersion: 2.7.0

One IMPORTANT oversight — Alarm VolumeWhilst I do prefer the G7 over the G6; the shorter warm up period, better readings, the size of the CGM itself is great. However, one thing I noticed that is a HUGE oversight in the next generation is within the app itself. The notification volume (specifically for lows) will follow your normal phone volume for whatever reason? For example, if your phone volume is low, the notification from Dexcom will also be low. On G6, this was never a problem, it would ignore your phone’s volume, and even the silencer switch after the first notification. I was confident my G6 alarm would wake me up in the middle of the night if I dropped low. The G7 following the phone volume rather than bypassing it and being as loud as it can is an insane oversight. I have been lucky enough to hear it at low volumes, but that’s because my phone is right next to me when I sleep. However, there have been instances where I can see that my glucose was in my low range for a long time, and I just could not hear it because I fell asleep and didn’t remember to raise the volume on my phone to 100%. This needs to be fixed right away as I would rather the alarm blare out and be loud and disruptive to my workday or being in the movie theater than to pass out in my sleep because the alarm didn’t sound as loud as it should. Please fix this oversight, I may have been lucky before to hear it, but who knows if that luck will continue..ALANC2000Version: 2.8.0

Wish I could have stayed with the G6First what I like: it’s much smaller than the G6, which is really nice. It also warms up way faster with only 30 minute warm-ups. So you’re not missing as much time. The graph is much easier to read and I really like the summaries of the week; you can change it from 3 hours, 6 hours, and 12 hours. It’s really convenient and not as much fiddling with my phone. Outside of that, the main purpose for the monitor, is really frustrating. For some reason, it disconnects all the time and takes 30 minutes to reconnect. It’ll tell me it’s because my phone is my than 20 feet away even if it’s literally on me. There’s also more times than not that it doesn’t connect to my watch. When I’m at work, I try to keep my phone in my desk (still right next to it) and it doesn’t connect to my watch. That part is more inconvenience than anything. But the disconnection is very frustrating, especially as I’m trying to track for pregnancy..Megs521Version: 2.1.1

Newbie ReviewI am very new to all of this having been diagnosed as type “1.5” a little over a month ago. This is the only sensor I have tried so far. Yes, there have been some issues…occasionally off readings, connection issues, Watch issues, bad sensor, etc. For what it does, the glitches have been relatively minor. Do I wish it were perfect, yes. Is it? No. Hoping they continue to take feedback & improve upon it. Most of the time my readings are within normal range of the finger poke readings. I run marathons & am counting on this being able to function properly with just my watch. So far, that component has been a total fail. Having the ability to link it to strava for linking/uploading exercise data would be huge! Especially if I could then go into the strava app & see a metric for how my blood sugars fluctuated during training runs & races. Overall impression, it serves its purpose. Could be better, but could also be worse..TLang76Version: 2.5.0

Alert volumeThis had been fixed in the past I thought, but seems to be occurring once again. When an alert comes through while also listening to music, a podcast, or videos, the volume of whatever is being listened to will change what seems to be sound sources/output, the volume will turn up all the way, and the alarm will blast while also blasting the volume of whatever is being watched/listened to. Once the alarm ends, the volume will remain high and on the different “output” sound (like the clarity/balance of the sound will be different), and eventually go back. This happens through CarPlay, normal phone sound, or headphones. It’s extremely disruptive and annoying to have the alarms adjust settings of other sounds. If there is not other sounds playing (music, podcast, video, short form videos like Instagram/tiktok, etc) then the volume plays at the phones set volume and operates as expected..UsermicheVersion: 2.7.0

Server crashed and erased all of my dataWhy, why would you make an app for a device tied to closed loop insulin delivery system that can just crash and then erase not only all of my data from last 5 months since I upgraded to the G7, but also the peace of mind I’m supposed to have having it tied to my Tandem pump. The app just stopped working. Then it forced me to sign in. Then it said I didn’t have an account which I have had for years. So I had to create a new account with the same info. Only to have to put a new sensor in (after just putting one in the day before). Again, this is tied to my insulin delivery system. I’m traveling. My wife can no longer get notifications. I have no alarms that I’m use to while sleeping in a hotel alone. Not to mention I have to have an additional sensor overnighted to a hotel now. Why would you just restart an app like that without warning people? What is wrong with you?.EcmprojectVersion: 2.1.1

App doesn’t work frequently but it makes up for it in allowing us automany.Dexcom g6 allowed me to use low power mode. This one does not and leads me to spending a lot of the time I pay good money for trying to get a app to stop crashing after even turning low power mode off. On a positive note, I LOVE the ability to turn off all alerts. It seems this one takes into account I am an adult who can choose if I want to hear incessant screaming even though insulin takes 40 ish minutes to start working and food takes time to kick in. I love that more than words can explain so I’m not too mad about the crashes. That alone makes it worlds better than g6 as I used to have to just not allow the app to use cellular data when in the car since I almost crashed over the sudden and non stop screaming while listening to music..Alice🧁Version: 2.8.0

I really like not having to stick myself but…I really like the G7. I do wish the app would be a little more user friendly. Meaning, I wish I could check my blood glucose whenever I need to instead of having to wait 5 minutes. That does not seem like a long time but it can feel like an eternity if you need it when your sugar is rapidly rising or dropping! My watch has stopped pairing with my G7s. I am not sure why. I have tried almost everything including updating the watch and phone. But it still will not pair. This probably has nothing to do with you (G7 app) but Dexcom in general. I wish there was some way to get help with this dilemma. I am a cancer patient. I will receive chemo every 2 weeks and MRIs every 3 months for the rest of my life (which could be & hopefully will be many, many years). I will need a way to get 4 extra sensors per year. I cannot get them without a prescription. I should be able to get it without one and through insurance and at the same cost but it is a problem. Not sure why. Lastly, dark mode would be nice. It is rather bright in the middle of the night when my low alarm goes off. Every 5 minutes. Sometimes for hours. Ugh. It is just a convenience for me (& most likely others). If it is already an option and I have missed it, forgive me! Thank you for hearing me!.YouropinionisirrelevantVersion: 2.6.0

The relationship between Apple and The G7.So many people are quick to criticize and don’t see the real benefit of the G7. Along with Apple Watches and IPhones you can really control your cgm and make your life better and control your diabetes. If you want to track everything down to your last step a paper journal is your best friend. You can find the information much faster and it’s permanently available unlike a phone that can be broken and lost. My Apple Watch alerts me way faster than my iPhone and my doctor monitors my progress and activity so adjusting my needs is a snap. My journal contains my sticks and meals for comparison. You are a diabetic and it requires work to slow or stop the progression of diabetes no one is going to do that for you. The G7 is an excellent tool to do this..MushanaterVersion: 2.2.1

This app is a lifesaver!I don’t get all the negative reviews. I’ve been using Dexcom 7 and the app for 5 months after getting diagnosed for type II. It is so easy and straightforward to use, the interface is very user friendly and I am constantly learning how things affect my glucose. It is a powerful, amazing, tool! With its help I have dropped my A1C from 7 to 6.4, but the really great data is the Time in Range and the GMI, which is basically A1C but over the previous 14 days. These are really helping me see the changes I’m making over time. No lab or home A1C test to wait for, I can just look at my phone and see! And the new update with direct connection to my Apple Watch is a game changer. Not having to stay with 20’ of my phone makes it so much easier to stay on top of..DKaboomVersion: 2.2.1

G7 app better than receiverI had to purchase the receiver bcuz my iPhone was a 1st generation SE. unfortunately the receiver only gathers info for 1 day. I have since upgraded my phone and I love being able to input notes, etc. However I find that inputting meals doesn’t work well, but that’s an easy fix. As well, yes, please increase the hours for pausing Alerts..Diana De RVersion: 2.3.0

AwesomeI don’t know what it is about medical technology that makes people grumpy. This app always works phenomenally for me..Nathan NathanielVersion: 2.2.1

Few suggestions…The app works well for me although the last few days of a sensor it’s over dramatic all the time even tho my blood sugar is stable. I would love to be able to customize more the alerts cause they are super annoying esports with headphones and speakers. I would love to be able to put in a different schedule every day since I’m a student. Also it would be great if I could monitor my sensor placement history to make sure I make a great rotation of sites. I love that there is a option for a widget but it never shows my blood sugar, only an empty graph so… The obvious part of monitoring the blood sugar is fine but the programming of the app isn’t great tbh..CanadianWilliamVersion: 2.2.1

Works well!After reading the reviews I thought, oh no, should I have stuck with the freestyle libre. This app has way better alarm features that suit my needs. I don’t have diabetes, however have postprandial hypoglycemia since losing 210 pounds. As such my sugars drop extremely quickly and being able to calibrate my alarms has been critical. I often silence my alarms, but since I don’t get symptomatic until my sugars drop below 2.7mmol/L, I needed to know when I was dropping quickly. The app works well for my needs. The only issue I had is the first 24-48 hours of a new sensor, dexcom tends to have lower projected values. Given that this system measures interstitial blood values and not blood sugars a lower projected value is expected. I would not recommend using a cgm value for insulin dosages, however it is amazing for monitoring trends and seeing how your body responds to food..SharkeatyouVersion: 2.2.1

Better than G6, still room for improvementThe G7 app (like the device) is a significant improvement over G6. There are some minor things that could be improved: 1. The today screen widget on IOS is often blank rather than showing the current reading. Despite having the app running all the time, the app needs to be brought to the foreground for this widget to pick and display up the latest reading. 2. The G7 widget is much smaller than the G6 version, and hence it’s not as easy to see the graph details. 3. I really only use the “add event” feature for insulin, so it would be nice to be able to hide the other options (meal, activity, note) or at least reorder then so that insulin is the first option..Geoff HardyVersion: 2.2.0

Honestly don’t get the hateG7 has been FAR better than g6. Not only is it painless and easy to insert, but I find that’s it’s far more accurate than g7, despite what the reviews say. I guess calibrating it works, but even then, I didn’t calibrate it much..The_skrunklyVersion: 2.2.0

Apple health integration now worksIn a recent app update (mid May 2024), dexcom G7 Apple health integration works. The user gets the typical screens to allow read/write data. Data from G7 appeared right after with the advertised 3hr delay..AboulfadVersion: 2.2.0

Could be a lot betterI’ve had a Dexcom g7 for about a week now and I’m not thrilled. I don’t have diabetes so the critical alarms that go off in the middle of the night for low readings isn’t something that’s going to save my life; despite that there’s no way to leave the phone and g7 connected and not get these alarms so I need to disable Bluetooth at bedtime. The g7 seems to consistently get into a state where it’s not registering data and the app tells me that it might take up to 3 hours to establish a connection. Overall I like the idea of getting blood sugar data every five minutes but this app and the concomitant device could do a lot better to be user friendly..$$$Tubby$$$Version: 2.2.0

Better than LibreI decided to change companies after a few incidents with the Freestyle Libre 2 failing multiple times. Now, after using this app, I find that it is FAR superior to its competitor in most respects. The readings are kept as individual points that you can refer to. Inputting records is super easy AND it allows you to input things later, if you get busy and neglect to do so, AND input the actual time, unlike its competition..Storm780Version: 2.2.0

Dexcom g7The dexcom g7 has been great for the first 9 sensors I have gone through, and they all lasted 10 days. Only once did I have a sensor error but it fixed itself after 30 minutes. All the other reviews I’m seeing say that it’s crappy and worse that the g6 and they weren’t getting readings but it was probably their receiving device..Dissticks 11Version: 2.1.1

Good so far but volume control drives me nuts.The app shares the same audio pathway as facebook. I normally keep the audio down for facebook because of the videos that auto play. Now i can’t because it also silences my G7 alerts..Stainless00Version: 2.1.1

Dexcom G7 Negative Reviews

Dexcom G7 app needs improvementThe Dexcom G7 app currently lacks quite a few options and features. Here’s a list of items the Developers should work on: Add 200 mg/dL graph height option. Additionally, this could be added to the “…” above the chart for quicker customization. Add 8 hour option to Glucose trend graph. Plot blood glucose fingerpick readings on Glucose trend chart to be able to easily compare with CGM readings. Add “DarkMode” option for easier readability, especially at night. Add ability to describe or select from drop down menu the Activity; walk, run, swim, bicycle, treadmill, etc. Add ability to select from drop down menu the Meal type; breakfast, lunch, dinner, snack. Add ability to input Medication that isn’t in the search. Insulin Dose Log under Glucose tab should show up to 10 glucose readings instead of 3-4. Historical information under History tab should show more data without needing to download Clarity app. Additionally, filter options for blood glucose, insulin, medication, meal, activity, and note would be nice. Add a better way to report app bugs, provide feedback, etc. under Profile > Support > Feedback. Move Sensor information under Connections tab to Glucose tab and all the rest under Connections tab to Profile tab. Connections tab should be replaced with something more functional like medication, insulin and activity reminders..XItzJustAlexVersion: 2.2.0

Cannot dismiss alerts from watchThis app is almost good. It’s missing two features that are standard in every other app in the AppStore. And with those features it would be 4 stars. 1. Most important. Be able to dismiss alerts from the Apple Watch. I get alert, dismiss the alert of the watch, but a minute later it alerts again. Making me have to open the app on my phone to dismiss the alert. If I’m in a meeting or somewhere important I can’t be pulling out my phone or having Loud critical alerts going off every couple of minutes for something I’ve taken care of. An even better feature would be to let me get a 1 minute quiet notification on my watch that I could clear before even setting off a critical alert. But as the way it is now, I’m going to have to turn off critical alert notifications, which is not a good thing. 2. This doesn’t seem like a big one, but it is. Dark mode. It exists on Dexcom Follow app, so I know there Devs know how to do it, and they should be using shared libraries, so why am I blinding my self at night to check my Blood Sugars? A device and technology so advanced it can tell me my blood sugar every 5 minutes just by looking at a screen, when just 20 years ago we were peeing on sticks, and not long before that peeing on the ground and watching for ants. But yet my retinas burn when I check my blood sugar. And my I get just as embarrassed as everyone stares at me thinking I didn’t mute my phone for the meeting. Please fix this..GaXIMUSVersion: 1.11.0

Sensors fall off; hate the activity tracker in appI have been using the g7 for about three months, so I feel like I’ve given it adequate time. I “upgraded” from the g6 for the benefits many did - shorter warm up period, longer wear, and smaller sensor. In only 3 months, I’ve had to have 3 sensors replaced; 2 fell off within a few days and 1 failed during the warm up. Because the sensors are smaller, there’s less surface area to stick to your body. HATE that, especially in the summer. Calling Dexcom for a replacement, or using their online form, has also gotten progressively more inconvenient and annoying over the many years I’ve been a Dexcom customer. Also with the g7 app, it freezes on me. And my LEAST favorite thing about it, though it seems minor, it’s still a nuisance. The activity button makes you slide for “duration” using increments of 5 min, but it’s SO ANNOYING to get it on the amount of time you want. Why did they make this unnecessarily frustrating? Just leave the sliding numeric option like the start time. I’m strongly considering switching back to g6 when my stock is out..Candace0601Version: 2.2.0

Useless app from overseasI used the G6 app during my travels, the G7 app cannot be setup from overseas, even if your residence is in the US. To start you are forced to allow access to location services ( setup screen locked until location access is granted), which in itself is an invasion of privacy. Then, contrary to the disclaimer, the location is used for comparison with the account address and the setup Is locked with an error indicating location different from residence as if one has to be locked in one’s residence. An invitation to contact technical support yields no result beside waste of communication fees from abroad ( delete and reload, create new account… ) and confusing explanations about geolocation allegedly not working in every country. It might be time for US developers to realize that the world extends beyond San Diego and Boston ! One thing is sure, on my return to the US, once my nine sensors are used up I will switch to another CGM ( FreeStyle Libre) or no CGM For US companies and software developers to be so dismissive of the rest of the world in 2024 is beyond belief! Contact suggested by Apple does not yield any result , the only suggestion by Dexcom support is to buy the receiver and basically not use / initialise the app while overseas. This is beyond belief in an allegedly global world!!! The western world view is anyone outside the west is a thief or a fraud and everything must be done to restrict or suppress his access! Pathetic!.AngryFrustratedJohnVersion: 1.11.0

Unreliable — NOT recommendedUPDATE: Gets worse and worse, 2 of 18 (11%) sensors failed during use and needed to be returned. NOT reliable in my opinion. App continues to crash and drops out without data as well as insulin records nog being recorded. Buyer beware — app is unreliable and does not properly record insulin entries. There is a bug in software that removes insulin entries. Multiple times after entering and verifying entry, I’ve come back and there is no data. As a medical device, the data is unreliable and I cannot trust it. Additionally, I’ve experienced “blackouts” where software will not load. When calling tech services they were unable to tell me what the committed up time is. Also getting through to support is neatly impossible and requires a yon of personal information which should NOT be required. Can not recommend if this was for a parent wanting to help a child Recommended to NOT use this product in my opinion, have shared with any provider who has asked. Just using up what came with prescription before checking alternative options. Also —> response from developers is disappointing and seems to be the same for every response. Asking us to use an automated response system which seems to make you use a ton if personal info just to submit. As a medical device, if is clear they do not care about end users..Bluesky105Version: 2.2.0

Critical Alerts Issue Makes App uselessDo not buy the Dexcom G7 sensor until Dexcom fixes major issue with app. This apps notifications mandate regarding Critical Alerts makes the app useless. There is a notification setting called critical alerts that completely overrides one’s ability to use the app in environments where complete silence is expected. Even when the phone is set to silence and the main volume is turned all the way down, the critical alert settings overrides all volume settings and sound a loud alert alarm. Within the app notification settings, there is a selection to disable the critical alert function BUT when you disable it and try to use the app, a message blocking the use of the app is displayed stating that the app will not function or register any readings unless one re-enables the critical alert setting. So, the app is effectively rendered useless because I cannot have this setting overriding my ability to ensure my phone remains silent in settings that require such silence. The question is, why Dexcom has designed the app with the ability to disable Critical Alerts but when you do, won’t allow your app to work at all and forces you to turn the critical alerts sound override back on if you want to use the app. This is completely unacceptable and must be fixed immediately..4cinemaVersion: 1.11.0

App Will Not Let Me CalibrateIt has been over a month, at least 4 G7 sensors. First, lots of incorrect readings with the incessant beeping saying I am low when I'm not, so I have to calibrate way too often, then, out of the blue, the app locks up and says it's still 'saving my last calibration' and won't let me calibrate anymore. I have to totally delete the app and go through the entire process of watching videos and all that to get it restarted so I can use the calibrate feature again. I've used these since the G5 and can't believe how absolutely terrible my G7 experience has been. I was up all night long with it going off, poking my finger and learning I'm ok, but there's nothing I can do with the sensor. I finally closed the app and somehow it turned itself back on because I was awakened by the incessant beeping again. The tech team says call immediately but that means bad sensor. How??? Seems to me it's a problem with the app that it keeps locking up after a few calibrations are entered. Even worse if it is the sensors because this will be at least the 5th, if not the 6th, that I have to constantly calibrate because readings are off. It's just been the last 4 sensors where I lost the capability to even calibrate. I am 'this close' to changing to libre after all these years!!!!!.MKKKGLWVersion: 2.3.0

Unhappy Camper!I HATE the G7! I was an abdominal G6 wearer and loved the fact that I, and I alone, knew I was wearing a CGM! The G6 was accurate and was a great help to achieve my blood sugar goals. This G7 announces to the world that I’m a diabetic using a CGM, which is no one else’s business; and needs calibrating all day long if I wear it on my abdomen (which my doctor said I could do!)! I might as well go back to finger sticks, just to maintain my medical privacy! Yes, the G7 is 60% smaller, but 40% on my arm is not acceptable. Having a G7 also means altering my wardrobe and my ward-robe choices —no more sleeveless blouses or shirts. I can’t be the only person using a G7 who dislikes having this thing on their arm. If the G7 is so great, make it work where it can be totally discreet for the patients wearing it! “Bug fix” the G7 so it gives accurate readings on the abdomen for those of us who wish to keep their medical treatment private AND still be able to wear the clothing that they want—not the clothing that hides a device! If the G6 technology worked on the abdomen, certainly you can “bug fix” the G7 to do the same! I loved my G6; however, this G7 is the pits! And yes, simply because it violates my medical privacy by announcing to the world with it’s visibility on my arm that I am a diabetic wearing CGM! I HATE that! Fix it, PLEASE!.Ace's SweeTie1Version: 2.1.1

Trying another CGMI used G6, then I switched to G7 as soon as it came out. Every month I have had some kind of issue- app freezes causing me to have to delete the app, losing all of my stats, & reinstalling; hours of no readings; inaccurate readings; app will not recalibrate; and sensor has just stopped working. Replacing the sensor with a new one makes me one short for the month & my insurance only covers 3 per month. I either have to pay out of pocket ($65 for one sensor) or do finger sticks until my insurance will pay for refill. I try using customer service online chat to get a replacement, but the chat rep acts like I don’t deserve getting a replacement because I had to be doing something wrong or I am too stupid to understand the insertion process. It is now 12:43 am. I have been trying for an hour to calibrate because my readings are 100 points too low & chat hours are only during the work day hours. I can’t find a phone number anywhere. Since I have to now wear the sensor on my arm & not my abdomen, I will contact my doctor for a Rx for Freestyle Libre. I am soooooooooo disappointed with the product issues. I am sooooooooo dissatisfied with Dexcom’s customer service..Early morning viewerVersion: 2.2.1

Loose control of life-interfering alarms..This company struggles to walk the (admittedly) fine-line between customer needs and covering their liability backside. As a result, the iPhone app is life disturbing. Dexcom overrides Apple and chooses its own settings, sounds and times to alarm. They have the weakest support organization in the medical community ever experienced. No second level or senior support to work with on the phone. Front line people are more like order takers that take volumes of information for a benign issue, put you on hold, then come back with the most maddening next question. Then another 8 minutes waiting the the next weak response. I am without a working system, in a foreign country and deleted the app so I could shut it up and get some sleep. And help is so close to zero. Nil. Then they offer to mail me a replacement sensor! Again, piling on my frustration. Do not commit to this system without understanding the PROS and CONS. UPDATE: As a response to this review, they offer to contact me. Of course, they ask volumes of information—most irrelevant—and do not provide the keyboard function for two required fields.

Obnoxious alarmsThe alarms on the app are the most obnoxious options available. There is no option for high glucose for a simple short beep… but there are chimes, police sirens, twinkling bells, or one that sounds like the doomsday alert just dropped, and they are persistently obnoxious. The silent tones are only available for 6 hours, which means my co workers get to be full stop annoyed with me literally every single 12 hour shift I work at the hospital, as well as my patients. This app needs a makeover. There’s not even an option to provide the designers that feedback. On top of that it is so glitchy. I don’t remember ever having this many sensor issues with Bluetooth connectivity to Dexcom g6. Please give us an upgrade and save everyone, their families and their co workers their sanity. When these alarms go off everyone worries about our safety, we can’t sleep at night without waking up our partners, and we are just as frustrated with our diabetes as when we didn’t have continuous glucose monitoring available for ourselves. It makes something that’s already stressful to manage 3 times more stressful, especially if you are someone who is super sensitive to auditory stimulation..Flashy&muichiroVersion: 2.2.1

Dexcom doesn’t care about their end usersDexcom is such a great example of a company whose employees clearly don’t actually use their product and that doesn’t care customer feedback. They should have raving fans with a product that is a game changer, but they can’t do the simple things to make customers like their product. I love having a GCM and it’s changed my life, but somehow every day I’m frustrated by your products be delighted. It’s frustrating because they’re small things that every other tech company can do easily- ex. dark mode is not hard. Launching direct to watch is great, but after over a year they only have a complication on one type of watch face. Much smaller apps and developers get this right immediately or soon after. Dexcom, I promise you if you create and actual product that customer like, you will sell more of your product as more people ask for it from their doctor. Only utilities ignore the fact that customer experience matters and impacts revenue. Do better please. You should be embarrassed by your consistently low app score. Woof..ProzaakkVersion: 2.4.0

Feels a little like a downgradeI used the g6 for years and after “upgrading” I feel like I’ve been downgraded on a lot of features. While I love the actual g7’s device size, painless insertion and included transmitter and tape, the actual readings are spotty and not as uniform as the g6. I also don’t like that there’s not a widget option for the Lock Screen like before. That was an easy way for me, or someone who doesn’t have my phone password, to quickly see what my readings were without completely opening my phone. The app never uses my calibrations, even when the readings are anywhere from 10-30 points off. The calibration sometimes gets stuck saying “still processing” days after entering it, preventing me from calibrating again. I find myself checking my blood with a meter way more than the first day calibration needs of the g6. I’m hoping Dexcom figures this out soon because I’d hate to go back to the huge and sometimes painful g6 to have good readings again, or to have a practically designed sensor that doesn’t give consistently accurate readings..Kayly820Version: 2.3.1

UghThe most recent update broke the widget... the widget is completely blank now and I have to click into the app to see what my numbers are. The widget chart over the past few weeks prior to this update was also incorrect. The line on the chart would be 3 hours in the past rather than the current line. For example, it would appear that I was dipping low, but if I looked at the app, it would show that I was dipping low 3 hours ago and was currently 145 and steady. Also, every single time I get a low alert, double alerts come through in slightly different sounding tones. It will make the noise and say I'm 66 ↘️, then .5 seconds later it will make the noise again and say I'm 66↘️...both alerts wanting me to acknowledge them on the screen. It's extremely difficult to log the amount of time you're doing a workout. It requires a lot of precision to get to the right number. Also, it really annoys me that it won't let you move the time to the future. I would like to log things accurately, but if it's 4:20 and I'm at a yoga class that starts at 4:30, it won't let me say my activity starts at 4:30. It will only let me put 4:20 as the start time. The odds of me remembering to go back and input it after the workout is over are slim. I like that they've attempted to add clarity info into the app, but it's very buggy. It takes ages to load, and often refuses to load anything for certain time periods, like 90 days, even though I've worn g7 since May 2023..Ceecee25Version: 1.12.0

Initially good, then problematic and inaccurateI’m currently on day 8 of my first G7 sensor, which is my first foray into CGM. The first 4 or 5 days were pretty good. Didn’t have much in the way of signal dropout on my iPhone 15 Pro on iOS 17.1.1. My Apple Watch Series 9 showed two bars about as often as it showed a number, however. Accuracy was good initially, usually within 10% of my calibrated finger stick readings, more importantly, the trends were reliable. Starting around day 5 or 6, however, readings became increasingly sporadic, with multiple instances of signal dropout. More concerning, the accuracy of both the readings, and the trends, are becoming increasingly inaccurate. My latest finger stick was 90, at a time the Dexcom G7 showed a reading of 180. Hopefully this is just an issue with this one sensor aging prematurely. The software is rudimentary at best. You can’t scan back more than 24 hours. One should be able to scroll through at least all the data from the current sensor, preferably 30 to 90 days. Meals can’t be named, they are just saved as “Meal” with total carbs input. They don’t show up on the graph, only on a separate tab. Yes, there are third party apps that can do a lot of this, but it would seem that these basic functions should be available in the native app. If my second and third sensors perform better, I’ll add an additional star, bringing it up to three. The software needs a lot of work to deserve more than that..PeriopdocVersion: 1.9.1

Poor communicationThe software has very poor communication between the iPhone and the watch. You’ve added the watch as a stand alone to the phone but I find it will work well for a few day the then just become unpaired. Talking to dexcom they want to stop and reinstall the software on both the phone and watch. I explain by doing this I loose the last 5 days of this sensor. Then I’m told the software isn’t up to date. The watch is suppose to be at 10.6 but there only works up to 9.5. So why is there a incompatibility? And of course nobody has an answer for that. I’m so fed up with Dexcom and the excuses. They throw sensors at it like that’s gonna correct. The problem. I might get one or two that work for the full 10 days I get them to wear. They’ll quit at nine days eight days, take your pick. I guess if I didn’t need it I wouldn’t be worried. They do have some good parts but lately all I’m finding is a lot of bad things. I’ve tried to get a hold of the supervisor to find out what’s going on and all you do is sit on hold till you finally get disconnected. I’m done..CaballoJimVersion: 2.3.1

I was hopefulI was hopeful that the G7 would be an improvement on the G6 but when I initially start a new sensor the readings are so inaccurate and the app alarms all the time. My readings are usually super high when starting a new sensor and don’t correlate at all with my glucose meter. I lose connection all the time and then the longer it is on my readings start to become critically low and I check on my meter and it is now where close to what my sensor is saying. Once I start getting the low readings within a day my sesor fails. I think out of 7 or 8 sensors I have only had 2 last the entire 10 days. I rarely had this issue with the G6 transmitters and sensors, and I had been using those for close to 5 years. I maybe had 2-3 sensors fail during that time. I prefer the Tconnect app and not only that the adhesive makes my arm itch so bad. I just want to rip the thing off within a couple days. I was excited to get the G7 sensors because of the shorter warm up time and it being all in one but after using them for almost 2 months I am extremely disappointed..Rinkrat78Version: 1.12.0

Alerts, and requesting replacements need helpWhen the sensor stays attached the app generally works, but there really needs to be a way for me to acknowledge a critical alert and silence it. Totally understandable that it is an alarm that needs a response but give me time to do that if I’ve physically indicated that I’ve heard it but I’m in a place or situation where I can’t just stop what I’m doing and respond to it immediately. I also have a terrible failure rate with sensors; I’m aware that I can request replacements and over patches, except that I can’t. The address field on the web form to request them loads my street address but won’t load my apartment number, so I cannot submit the form— this is also the case on the customer help form other reviewers have been directed to use! Address validation is fine but I need to be able to enter my address manually on your web forms if your address lookup scripting can’t find it. There’s nowhere in the app to enter my address manually..FrustratedBahVersion: 2.4.0

Absolute garbageDon’t waste your money. Get a Libre 3. I ve been a Libre user wanted to try the g7 mainly because of the Apple Watch difference basically I though you could look at your watch and see your blood sugar. But to my surprise g7 only checks once every 5 minutes and that’s garbage unlike Libre that is constantly updating every second. And when your T1 that’s critical the sensor is extremely hard to apply as the applicator needs a lot to spring then you need to release the sensor from the applicator which itself can cause problems and this is all in the first hour now my phone keeps getting annoying notifications by the way the first sensor was faulty and would not pair with my iphone15pro max I bought six of these out of pocket cause my insurance won’t cover more than 2 a month and since they don’t last as long as the libre3 I’m out of luck I feel completely ripped of since customer service doesn’t care I would only recommend these if you’re eitherT2. Or a lazy parent of a child withT1 cause these are garbage.Expedia is a scamVersion: 2.2.0

A significant downgrade in quality from the G6 appI get it, developing medical tech is hard and the UI/interfaces for the device itself comes secondary. But these are pricy devices and the software is lacking The G6 app was much, much better (but far from flawless itself). G7 sensor is great and I love it but there is no reason why the sensor improves generation by generation, while the app gets worse. Actionable feedback for the devs Feature requests: - [!!!] Bring back the widgets. Hate having to unlock my phone just to check my glucose levels. - [!!] can we have oauth or some better way to use Dexcom share? I get logged out randomly which is whatever but I hate having to a separate account. I’d understand if this is for compliance reasons though. - [!] Clarity should be merged into the sensor application or be coupled more tightly. - [?] A public & documented API would be nice. I don’t want to reverse engineer endpoints or hook up share in some hacky way for writing integrations with other services or my own programs. Bugs: - app initialization is flaky. It will take ages at times and be instant at others. This could be caused by low power w/ no background refresh but I’d still like a way to have it be fast regardless - random crashing during initialization. Not sure why, didn’t even ask me to file a report. I assume the telemetry already collects that but it’s somewhat frequent of an issue.DinqeroVersion: 1.9.1

Many Serious ShortcomingsThe connecting to a new sensor is terrible. While the app usually gets around to connecting, it is slower than any other Bluetooth app. The UI keeps circling back to asking for the sensor number, and asking if the sensor is inserted. No status information is given. The coordination between the watch and phone when setting up direct to watch is similarly terrible. Stupid doesn’t begin to describe requiring watching a video that requires WiFi connectivity when setting up direct to watch. An ‘F’ grade seems too high for all the UI/UX regarding all connectivity flows. While I understand that some alerts are critical, forcing the user to turn them on just encourages turning the app off! A more refined approach would be appreciated, as I cannot use the app in most public settings. The display of data, especially allowing one to view individual measurements, is fantastic. Unfortunately this does not come close to overcoming the limitations. The last few releases have done nothing to address these limitations..Matt55hewVersion: 2.5.0

G6 is so much better!The G7 sensor/app is beyond horrible. Currently it’s giving a reading of 53, I checked my sugar and it’s 115. Used it as a calibration and it says it’s unable to use as calibration. It was calibrating for 8 days and wouldn’t let me use an updated number, uninstalled/installed the app and it at least got rid of the 8 day calibration and give 5 minutes to accept (or whatever it said). Now that I can put my checks in, it refuses to use them. Of the 3 or 4 I’ve used so far, 2 have quit working a couple days before they were set to be changed. Made a call after the first one and was told the old sensor has to be at least 20 feet away from the new sensor. I wasn’t aware of that and had it next to me when I changed and it was still reading the old sensor even though that one was removed from the app. Sorry this is confusing, I’m beyond frustrated with this stupid sensor. Only nice things is that it’s slimmer and one piece instead of two like the G6 (give me the slightly larger, two piece that worked!!!)..57);33:)$8Version: 2.3.1

DON’T DO ITSure, I love the 27 minute warm up time for the G7 vs. the 2 hour warm up of the G6. But that is the only thing I like. This app is so awful and I hate it so much. I cannot wait until I’m out of G7 sensors and will beg my doctor to go back to the G6. Pros: quick warm up time Cons: sensor insertion is harder, it has to be on your arm (I prefer the stomach), you get signal loss all the time, the sensor adhesive is so itchy, they require an additional sticky patch which is annoying, the app often doesn’t work, I’ll get a notification saying I’m 147 and then I open the app immediately and it says I’m 200, the app runs more slowly, the sharing feature doesn’t work and requires a re-login but then gives you a blank screen and won’t let you log in, it alerts you twice for lows and tells you you’re urgent low and that you’re just low, the calibration feature doesn’t always work, sometimes my real numbers are way off from what the Dexcom is saying, and the alerts/notifications are plain WRONG. Just to name a few..CCS502Version: 2.1.1

Not a tool for weight lossMy doctor prescribed this tool for me to help me get my blood sugar controlled. To reverse my type 2 diabetes. However, this very expensive tool provides no insights to facilitate losing weight. The instructions describe the types of carbs and various calories that impact insulin. But the app doesn’t have the capability to input what one ate. Instead it relies on the person to use another company’s app or nutritional information to measure only the carbohydrates and not the type of carbohydrates. Any calorie will trigger insulin production, but Dexcom is quietly advocating a low carb diet. Exercise is another input allowed by dexcom, but it relies on the user to figure out the intensity, and it doesn’t have input for calories burned. Seeing the blood sugar trending is interesting. But there’s no ability to export the information to report on it or to compare it over time to determine progress or regress. As a tool for weight management or lifestyle change, it fails miserably. For a tool that will help one determine how much insulin one needs to take, great..ToomediumVersion: 1.11.0

App not working properly/bad sensorI got my first bad sensor my first three were fine but my current problem is the app, must be a new bug from the most recent update because i now can’t calibrate it and haven’t been able to for five days which is a problem because I’m pregnant. It’s bad because i need accurate readings so i can take my rapid insulin, if my blood sugar is low and the app is telling me it’s high that’s not good for a normal diabetic. What makes it worse is I’m pregnant doing that doesn’t just have the chance to harm me but my unborn baby if my blood sugar is actually high and is above 200 my baby is also having high blood sugar if it’s low like 56 than she is also have low blood sugar so if I take my insulin at the wrong time because the app is not telling me correctly that’s a serious problem. PS:And I can’t use my glucose meter because my insurance is covering for the Dexcom they are only covering one strip a day and my strips are expensive..MarieJungeVersion: 2.2.1

App stuck on calibrations and support doesn’t seem to be working on a fixUpdate 9/9: stuck on calibration in progress again. Can’t seem to get past 30days without having to delete and reinstall the app. Additionally I’ve found out that each time you delete the app because of this glitch, you have to reinstall on your watch to reconnect to direct to watch. Update 8/5: still having to delete the app and reinstall to calibrate. July Update: instead of me calling you guys or putting in another ticket how about you please review the multitude of cases already in the system about the calibration issue because SURPRISE your web form at the link you told me to go to is broken. Get it together. Original: I keep writing in and calling support about the app getting stuck on the calibration process and the only solution is deleting the app altogether and start over only until it inevitably happens again. Keep cranking out newer models instead of fixing what’s actually bad with each model/version..Brenna LeighVersion: 2.3.1

Home Screen seems clutteredComing from the G6 app, the G7 Home Screen seems messy. Keep in mind: I check this 30x per day. The only info I want from it when I’m checking my blood sugar IS my blood sugar. So when there’s all kinds of additional info for my 14 day average and other things on there, it only gets in the way. Please, simplify the Home Screen. Additional info is cool and all, but put it on a second screen. Secondly, if I’m going low AND it’s at a fast pace, it’s wildly obnoxious to get a “low alert” and a “low glucose soon” alert to tell me I’ll be at 55 or less in a few minutes. Please don’t make me hit “ok” twice for anything. I cannot stress that enough. Give me the option to say “ok” to 2 warnings at the same time. Low blood sugars are frustrating, and I know when they’re happening. When I have to hit ok twice in the app the acknowledge that my blood sugar is low, and it makes a lot alarm both times, it drives me off the wall..Danger RicVersion: 2.2.0

Disappointed in SafetyI fully understand how to use the app, and how to make sure that alarms are not silenced. However, one of the key differences in this version of dexcom is that there is still no widget available to quickly view and display the blood sugar reading. Previously, there were more guidelines put in either via the FDA or dexcom itself, that you would not be silencing alarms, or able to quickly view blood sugar data unimpeded. In future updates it would GREATLY, improve the lifestyle and freedom of other diabetics to be able to quickly view their blood sugar without needing to unlock their device and separately open the Dexcom G7 app. This sounds minor, but it’s some thing that would greatly improve just the ability to access and peace of mind of the user. Just some thing that I have noticed in the few months that I’ve been using this system that would help tremendously as it is reductive..McNamara555Version: 1.11.0

Server crashed and erased all of my dataWhy, why would you make an app for a device tied to closed loop insulin delivery system that can just crash and then erase not only all of my data from last 5 months since I upgraded to the G7, but also the peace of mind I’m supposed to have having it tied to my Tandem pump. The app just stopped working. Then it forced me to sign in. Then it said I didn’t have an account which I have had for years. So I had to create a new account with the same info. Only to have to put a new sensor in (after just putting one in the day before). Again, this is tied to my insulin delivery system. I’m traveling. My wife can no longer get notifications. I have no alarms that I’m use to while sleeping in a hotel alone. Not to mention I have to have an additional sensor overnighted to a hotel now. Why would you just restart an app like that without warning people? What is wrong with you?.EcmprojectVersion: 2.1.1

GARBAGEThis app is terrible. I wish I had just stayed with the g6 or better yet, gone with a different company other than Dexcom. Very frequently since I started using the G7, I wake up thinking my sugar is fine, just to see that the app was malfunctioning again and not giving me any notifications. I make sure at night that all my settings are good, volume up, and then when I wake up, my sugar could have been 40, or 300, and the app has not notified me once throughout the night. Then, once I close and re open the app again, it starts giving me notifications. It happens way too frequently. My A1C has literally gone from 5.5 to 6.5 since I started using this terrible G7. Only good thing about it is the 25 minute start up, but I would much rather have stayed with the G6. The g7 app is so bad, and it doesn’t seem like Dexcom is doing anything to fix it. If I do not see an improvement with this app very soon I will certainly be switching to a different company. DO BETTER DEXCOM.JerrryyyyddVersion: 2.2.1

Only Works First 5 DaysAfter having a Freestyle Libre 3 for a while, my insurance stopped covering it and made me switch to the g7. Gave it a shot and have been on it for a month now, and every single time it has been the same. The first 4-5 days it works fairly well and the accuracy can sometimes be a little off, but usually isn’t too bad. However, on every single sensor I have used at this point, it stops working after day 4-5. Wildly inaccurate readings that jump all over the place. Caused me to give myself a bunch of correction insulin, only to find out by pricking my finger that I was actually already in range, and had just given myself a big dose of correction. Had to immediately scarf down food to avoid crashing. Will be immediately switching to a new sensor. Do NOT use these sensors. They only work 4-5 days when they are supposed to last 10, and can cause actual health emergencies from the wildly inaccurate readings. Cannot believe these are even on the market..ATPVersion: 1.11.0

Absolute garbage.This new G7 platform is the biggest piece of garbage Dexcom has ever created. It is astounding how often my sensor loses connection with my phone. I lose connection when I am at home and my phone is within 5 feet of me. I get intermittent connectivity when I go to the gym during off peak hours where it is not crowded at all. When it is super busy at the gym, I lose connection THE ENTIRE TWO HOURS I AM THERE. I lose connection when I go to a moderately crowded music event where people all are congregating in a similar area. For the amount that I pay for this product (which is a lot), I expect for it to work all the time, in every environment, regardless of how many other people are there using their Bluetooth devices. I am a very active individual that is always on the move and who requires having a stable connection at all times. The only redeeming quality that this product has is the short warm up period. If it weren’t for that, I would give this a zero..Alex CritchettVersion: 2.3.1

Glitches upon glitchesAs someone who works in wireless sales, I know my way around hardware and software. The Dexcom G7 app falls short in multiple ways, specifically connection issues and app glitches. I am sporadically losing signal on my iPhone 15 Pro and have called tech support at least 3 times to file tickets regarding my poor experiences. A new issue I have with G7 that just started today is the app immediately prompting me to log in (I never logged out) and then taking me to a dead link web page when I click log in. This is after todays sensor change and a network settings reset just for safe measure. I’m not sure why the Dexcom team can’t get it right after 7 iterations of CGM technology. I never had these issues with Freestyle Libre and if it wasn’t for American insurance and pharmaceutical companies jerking everyone around, I would still happily be using that system. Hopefully Dexcom gets it together..HeartbreaktoneVersion: 2.1.1

Unacceptable sound optionsThis is a pretty decent app, but it’s extremely difficult to live with. It completely takes away your ability to have a silent phone. You can set alerts to vibrate, and turn off your sound, but it will still sometimes override and blare alerts. You MAY NOT disable critical alerts, and you can’t use ‘silence all’ for more than 6 hours at a time - not even enough for single nights sleep (also, when silence all elapses it won’t revert to vibrate). One of two things are mandatory changes: - allow a true silent mode, indefinitely - disable critical alerts Put the user in charge, not beholden to some developers/product-managers/lawyers view of what should happen. Make me click through scary warnings, fine. But ultimately this is a currently a user-hostile app, only possible due to a desperate need for CGM data and people being locked into an option.ImnotyoursaleschannelVersion: 1.12.0

App creating incorrect sugar readingsI’ve been on dexcom g7 for about a month and half now and this is the first time I’ve had an issue. Throughout the night my sugars read high. So I changed my pump and the readings still continued to read high for another 4 hours. When I tested with a meter it said I was at 322 still high but better then 600+ my sugar then dropped to 112 which was still not accurate. This afternoon I was not feeling well again so I took my sugar on the meter my dexcom was reading 133 my sugar was 242. I’ve had to calibrate several times. The sensor is only a week and haven’t had issues till now. I never had issues with the G6 this needs to be fixed because incorrect readings that are connected to a pump to correct sugars can be extremely dangerous. Or cause death. Technology isn’t perfect but explain why the G6 never had reading issues where G7 does? This is saddening.McsnogiodVersion: 2.3.1

Buggy and unreliableWhile the G7 system has some user experience improvements like a faster start time and easier infusion, both the app and the sensor/receiver interface is horrible. I never once had issues with the g6 application, and the slight improvements in hardware do not make up for the poor software performance. The app works less than 1/2 the times I go to open it - most of the time it simply refuses to launch and I have to manually close then reopen the application several times before it ‘catches’. When I do get it open it takes up to 30 seconds for it to ‘update’ and show my current readings. Beyond this, my phone/receiver is constantly losing connection to the sensor despite being less than 20 inches away, while other Bluetooth devices run fine at 50ft+ Multiple issues need to be resolved for this system to be with continued use.BobbybobbibbVersion: 1.9.0

CalibrationThe Dexcom G7 continuous glucose monitoring (CGM) system offers significant improvements in sensor accuracy and user experience, but it still has some shortcomings. One key issue is occasional signal dropouts, where the device fails to send data to the connected smartphone or receiver, leading to potential gaps in glucose monitoring. These dropouts can be particularly concerning for users who rely on real-time alerts for low or high glucose levels. Another common complaint is the adhesive, which can fail prematurely, causing the sensor to dislodge before the intended wear period is over. Some users also note the calibration on the G7 not working properly sometimes a highest reading can cause the person to take more insulin when he really doesn’t need it, While the Dexcom G7 requires valuable improvements, these missing features and technical glitches need to be addressed to fully optimize the user experience..Aqftkn77ffVersion: 2.3.1

Problems Dexcom 7 reading incorrectI’ve had the Dexcom 7 now for several months and at the start it seem to be ok, but as far as providing a correct reading on my meter it didn’t it has been reading as much as 150 points and now after replace the current sensor it when to the extreme lower end of the scale as low as 47 which I knew wasn’t possible, if I were using Dexcom 7 to administer insulin I would be dead by now. It’s not dependable at all in my case. I calibrate the sensor all the time and it still isn't reliable. I at and end with this system I cannot depend on it at all. And one more thing the sensors are not holding on like they should or falling and have to replace them as directed by the meter. I’ve complained to my provider and to a representative from Dexcom and was told that it hasn’t been fully developed my reply was then why was it released for use. Bobby L.

G7 Apple Watch App is awfulThis latest update to the app does at least show your glucose value on the screen and if you press the button it shows you graph. The MAJOR problem is that you cannot see these values unless you allow notifications on your watch. This ultimately silences notifications on the phone. If you turn off notifications on the watch, you do not get and values, just the lines, and when you press the button it says Action Required. No Readings. Check G7 app on phone. You’re a 3 billion dollar company. Please hire some programmers to fix these basic issues. The latest update is also worthless when connected to your watch as you no longer get any alerts on your phone. The small vibrations that you receive on your watch is a waste of time. These will never alert you, or wake you up. My comments from my previous post are still valid. They need to hire some programmers who understand IOS..HannahF!1824Version: 2.3.1

Partially FunctionalGenerally the interface of the app is good, clear and straightforward, like the G6 app. My main concerns are: 1. The ability to dismiss the reminders that notifications are turned off. I use the Tandem X2 pump’s notification system as I prefer their sounds and options and I don’t want multiple instances of the same notification. The constant reminder every time I open the G7 app is annoying at best. I use the G7 app primarily for the watch complication, and I would prefer the option to disable these reminders if they’re enabled on another partner app. 2. The app freezes on the Connections page, so I cannot connect it to Apple Health or any other monitoring partner functionality. Currently it’s throwing a “Server Error” pop up when it feeezes, but even that can’t be dismissed or interacted with. This is a new development, but this desperately needs a fix..Katie KellertVersion: 1.12.0

New G7 is horrible and known issuesThe new G7s are known to have connectivity issues and readings that are way off. My son and I both wear one and his gives the most inaccurate readings where it says critical low around 50 but checking finger pricks with two different machines, his blood sugar is actually over 200. Mine has issues with staying connected to the Dexcom app and four nights now where I have been woke up between 2 and 4 AM because it goes off saying disconnected. I have changed the G7 out for a new one and still happens. My son’s doctor has said Dexcom knows there are issues and are sending out a new version of the G7 to try and correct the issues but are still allowing the faulty ones to be used so as to not lose money. You can tell the difference because the new G7s will have the numbers underlined on the box versus old ones that do not.

Better than G6 but still awfulTwo steps forward, one step back. G6 got one star, so I guess I’ll give this one two. The alerts seem to work ok for me, but I hate being unable to use an Airplay speaker without the risk of blowing the speaker out if my sugar goes low. I also wish there was a way to see my sugar without unlocking the phone. G6 had it in notification centre, G7 somehow does not. On the other hand, G7 has a nice widget (although it doesn’t update in real time)..KnattyVersion: 2.2.1

So many design flawsAlarms go off every few minutes even after you acknowledge them which is super disruptive. Calibration says to wait five minutes but jammed for days while readings are hugely inaccurate. Tried to reinstall the app to fix this but it wont let me login because I’m travelling and my residence doesn’t match my location (so diabetics aren’t supposed to travel? Who designed this…?). App on watch doesn’t display a reading unless you manually refresh it. The list goes on… When it works it’s great so forgive me for the complaining but for a redesign from G6 I feel like so many things just got worse :(.Kelsbg123Version: 2.2.0

This App forces me to cede control of my phone!I’m new to the app and system, and thought I’d give it a try. My problem with this app is that it forces me to cede control of my phone to Dexcom. It has a critical alert feature that plays sounds that I CANNOT TURN OFF! I cannot have my phone bleeping at me, when I’m in court proceedings, or when I’m in rehearsal or performance of the various classical musical groups I’m with!!! If I turn off the critical alerts, the app refuses to work! If I turn off notifications all together, the app stops working. I feel like I’m being held hostage by this app! Gross! I can feel my phone vibrating, I DO NOT need sound!! What about deaf users, huh? Get your effing act together, or there’ll be a class action lawsuit for taking control of people’s phones..JasonhyfrydolVersion: 1.11.0

Much worse than G6Addendum The Clarity app that comes with the G7 sensor is TERRIBLE My data has been stuck at the same values for a long time. And the results don’t make sense. PLEASE FIX While I wasn’t fond of the G6 sensor, bigger and crappy transmitter, the Clarity app was great. Lots of functions with great graphs and info. Now in the G7 app, Clarity is built in it and I only get my Glucose curve. Why do that?? Please combine the old G6 Clarity into the new G7 app, PLEASE!!! Also, I hate that I am constantly getting a Lost Sensor Contact message. Even when I’m very close to my phone. Thanks Addendum I am a physician, and I was so impressed with the Dexcom G6, that I switched to the G6, even though the Libre 2 lasted longer and didn’t have that annoying transmitter to apply. Why? CLARITY WAS WONDERFUL But alas, Dexcom Clarity with G7 is nothing like the old Clarity. I will continue with the G7 until I do a complete 90 days to see if the app improves. If it doesn’t improve, I’m back to Libre 2, maybe Libre 3 will become available Thanks.Dutch BobsterVersion: 2.1.1

Warning!!I had a couple of malfunctions when traveling, and in the past, I simply had to reinstall the app. When I tried this in Thailand, even though I was able to login with my password, it would not let me reinstall the app because my location did not match my residence!!.AceanandaVersion: 1.11.0

App lets product downDon’t reinstall the app if you’re out of your home country, even if tech support asks you to, because you’ll have to create a new account for whatever country GPS says you’re in - I live near a border and can see how big a mistake it is. I was without any readings for a day because I didn’t have time to get a new account - with a new email address, and now I’m getting readings in the wrong units because the foreign country it made me create an account for uses different units? The app has no way to switch. Contacting support or getting help through the app is terrible and their iOS devs decided to make it that way: it doesn’t use the apps’ account info, fill in contact info from keychain, or even sensor details it already knows: even searching for help in the G7 app will bring up G6 articles because the app sucks. Setting up the app can get stuck in parts of the unskipable intro because it doesn’t let you tap next, but tapping for the text version allowed me to scroll down and hit next. One day a few weeks after an iOS and app update the app decided my iPhone was broken out of jail and gave an error. It’s a stock phone and their developers are bad if they think a sandboxed app has any idea..NarrbcVersion: 1.11.0

Do not buyI highly recommend Libre.. this has caused me sleepless nights and ridiculous readings that are NOT at all accurate. The absolute worst BG reader. I’ve contacted them way too much for replacements for nothing to actually work..LT11999955Version: 2.5.0

Need more improvements2 star app for health related is pretty awful.JoecacsVersion: 2.5.0

Won’t connect with my iPhone 14I’m from Canada, travelling in Italy. I have no idea what the problem is, but I keep getting a sensor error message. Dexcom tech support didn’t get back to me. Agree with the other reviews, this app is abysmally poorly designed and Dexcom does not provide support..Juliana134Version: 2.5.0

Remove forced alarmsTried signing in with my old account, told me account doesn't exist. Tried making one with the same email, told me I need to sign in with this email. Tried resetting password, didn't let me because I wasn't signed in. Also not everyone wants alarms that cant be turned off, I think no one wants that. My phone rang during the exam because I couldn't turn off the notification and I almost got painted as a cheater..Shaquil O’nealVersion: 2.4.0

Fails to even openDexcom’s most recent update still will not launch or open on my iPhone 15 Pro Max. How embarrassing for Dexcom..Kahuna2Version: 2.4.0

InaccurateI love dexcom the sensor has made my diabetes experience a lot better but I’m writing this at midnight and my finger pricker says I’m 24.0 (CANADIAN) and my dexcom says I’m 3.3🤦🏻‍♂️.Ilovekickthebuddy1245Version: 2.4.0

Notification issueI am not getting notifications even with all my settings configured correctly. Whenever I close the app it says I will no longer be notified unless I keep it running in the background; but when it’s on in the background I am STILL NOT receiving notifications unless I open the app. All settings have been triple checked. So if my sugar is dangerously low and I can’t open the app I will not get a notification unless I physically check. Good work Dexcom..J3697Version: 2.4.0

Alerts problemG6 app was way better than G7 Alerts seems to be not working and the app won’t notify you as regularly as g6 when you are high or low..NB_200Version: 2.4.0

It’s better not updateAfter update to 2.4, the app doesn’t run in background. The reading stop and I have to close the app, open again and wait for a few minutes to get the reading again. Don’t know why they update the app.Frank@iPhoneVersion: 2.4.0

Forced critical alertsApp doesn’t work unless you enable critical alerts, forcing you to receive sound alerts. This along with the sensors only lasting 10 days, needing to scan QR codes and hold on to your applicator for the full cycle, and various other inconveniences within the app make the experience with the Dexcom G7 much worse than the Freestyle Libre 2..FaultyVaultyVersion: 2.3.1

Can’t use itKeeps saying I’m not in my country when trying to start up the app. Teq support was not helpful at all. Stuck without a Dexcom. Upgrade was a terrible idea. Super disappointing.Frustratedaf16524Version: 2.3.1

TerribleTerrible, support is usless, full of bugs, notifications are WAY to loud and it makes my phone run like absolut garbage, Dexcom you better fix this app.Creeperslaer747Version: 2.3.0

An unreliable failure and far from an upgradeI have so many problems with the g7 constant sensor failures, multiple times where the sensor just peels off, inaccurate readings, the list goes on and on, these devices are absolute garbage and my insurance only covers the g7, why would you create a new device only for it to be a downgrade in quality from the g6?, in my honest opinion the g7 needs to be taken off the market until it is fixed, has further testing done and is actually safe for diabetics to use, this device hardly gives me any peace of mind and causes me so much wasted time and stress dealing with sensor issues. Time for dexcom to get their act together..Idontcare11Version: 2.3.0

Step backwardsUpgraded from the G6. The G7 is great when it works, but it doesn’t work more often. Been a few months and haven’t had one sensor last the full 10 days. Have had to reinstall the app several times because calibration gets stuck, sensor fell of after taking a shower, have had to purchase 3rd party over patches, readings jump up and down within minutes, false highs, false lows, upper arm location is very difficult place as it keeps getting stuck in clothing or gets bumped (painful). I think the only reason to have it there is so it’s visible and good for marketing. The adhesive is so small that they had to add on over patch as a cover up, it still sucks..Salim MooraniVersion: 2.2.1

Failed sensors + false alarmsI’ve gone through 4 failed sensors that haven’t even lasted me at least more then 3 days!!! The false alarms at night especially are REALLY annoying and scary in a way. What I mean by scary is, one night my g7 was saying I was low, when really my actual sugar levels were high. If I had taken juice, my sugars would’ve spiked even HIGHER!!!!! I must say, the Dexcom g7 is much more comfortable on my arm, but that’s really the only pro I can name!!.G $/!!,$828’Version: 2.2.1

OppressiveYou know what’s great for helping to keep your endocrine system in good order and your blood sugar levels consistent? A good night’s sleep—which I haven’t gotten since switching from the Dexcom G6 to G7, thanks in full to the new G7 app. The app’s abuse of the notification system feels downright oppressive. It doesn’t matter how many times I calibrate the sensor, the app indicates false lows frequently overnight (my doctor says it’s an issue that Dexcom is familiar with and that their rep refers to them as “compression lows”). The app’s refusal to work unless “critical alerts” are enabled in iOS settings is myopic. Dexcom knows its results aren’t accurate. That’s why they state that the sensors are not a replacement for glucose tests. So why enforce critical alerts? I just want the CGM for general trend analysis to help me fine tune insulin delivery. The app, in it’s current incarnation and with its present level of accuracy is absolutely, by no means deserving of a critical alerts entitlement. This app never should have gotten through app review. The critical alerts are heart-stopping in their level of obnoxiousness and they’re impacting more than just me. My spouse flew out of bed ready to scoop up our kids up and flee from a fire at 4am when one went off the other night and then couldn’t fall back asleep thanks to the adrenaline rush that induced. My *actual* blood sugar level when I tested that night was 4.8, the night before when it went off it was 6.5, this morning when it woke me with a start at 4:10am it was a perfect 5.0. I’ve been woken by false alarms every night this week except the one night I had the foresight to revoke notification permissions for the the Dexcom app before heading to bed. I’ve tried to work around the issue and automate things with Focus Modes or the Apple Shortcuts app, but it’s futile. There’s no way to automate the silencing of critical alerts, no way to customize the sound or sound level, and the app refuses to function with them turned off—rendering the widgets useless and throwing up a big red screen obfuscating access to any of the app’s functionality until critical alerts are turned back on..Le CostarVersion: 2.2.1

Annoying alarmsThere is no way to put it in silence for more than 6 hours, so for me it’s not possible to sleep the entire night without 1 or 2 alarms going off. I’m so annoyed by this, and really tired… i understand why there is alarma, but please during the night I really don’t need it!.MuadrynaVersion: 2.2.0

Not compatible with my Apple Watch 3One of the best features of having a Dexcom was seeing the reading on my watch. Upgraded to G7 to find out it’s not compatible. My watch is fully functional and I have no other reason to spend hundreds on an upgrade. I see no reason it couldn’t have been compatible like the G6 app was. Frustrating to have to take a step back in my treatment!!!.Regina-PhalangeeVersion: 2.2.0

Pause notifications!Please allow me to have an option to silence notifications for a set time limit. If I wake up low, treat the low. Why do I have to listen to the alarm go off for the next hour and a half while I try and sleep. It’s to the point I need to shut off my phone to shut up the app..R0ssr0ss83Version: 2.2.0

Device great, App not greatA definite improvement from the G6 app, but still rather buggy. Has stopped syncing with Apple health, and Siri keeps running into a problem when ask for my glucose reading..AppleReviewer0102Version: 2.1.0

Stay on the G6 or don’t use Dexcom at all.I cannot properly express how much this thing SUCKS. Notifications do not work ( I literally have every single notification option turned on and my volume at 100 ), follow app doesn’t work properly with the G7, not to mention the actual sensor IS NOT WATER PROOF. Fell off after being exposed indirectly to water for 45 mins. Complete waste of time and money..PandaPuckPensVersion: 2.2.0

Pile of garbageLiterally the biggest downgrade of all time. G6 had its cons but was amazing and reliable. This piece of trash has no pros only cons. Firstly the never stable graph. Secondly the sensor failures, I get that you can have sensor failures but to have three THREE sensors fail in one week is absurd. If you are going to release a product that relies on someones life and saying its our fault please for the love of God do not Because this is getting to the point CRT.Manaking124Version: 2.1.1

Not goodI don’t think the app is great. Seems so flawed. One Minute my BG is 11.7 going up. The next by is 9.5 horizontal. That a huge difference especially when your correcting. I’m going back to the g6.ImhgvtdarhnhjVersion: 2.1.1

Not safeApp keeps losing signal. Receiver is better but this is my second sensor which has given me dramatically wrong readings. The 1st sensor was off by 4levels, and the one I have in now said that I was at 9 mmol when in fact I was at 19. I am going back to the much more safer dexcom g6.Hmd160463638Version: 2.1.1

NEEDS WORKThis app definitely needs to work out the bugs. Loosing signal all the time, alerts are delayed. I really hope the issues with travelling out of country have been worked out because that is crucial..JordelfVersion: 2.1.1

I have a headacheI haven’t even been able to set up the app yet. I made a mistake with my son’s username which I didn’t notice at first and so I tried to change it but I’m not allowed to apparently. I can’t just delete him as my dependent and start again either. This is a bad beginning to our journey with this device b.No puppy yet!Version: 2.1.1

Constant never-ending connection issuesI have an iPhone 13 in my pocket less than 2 feet away from my sensor 24/7 and have continued issues with connection about 10 times a day. This G7 product is basically useless as a CGM. I’m on MDI right now and would not trust this product to control a pump if I got one in the future. Absolutely horrible product, this should not be approved by Health Canada..Hvac driver mikeVersion: 2.1.0

Worse than the G6I can’t tell if it is the actual technology of the new sensor or simply the new G7 app, but I’ve used four of these new G7 sensors and the longest one has lasted me was 5 days (the lifetime of each sensor is supposedly 10 days). One of the sensors failed immediately following the warmup, so it had a total working time of 0 minutes. When the sensors do work, it is for the first day or two and then the readings lose accuracy very quickly. You will be getting urgent low alerts when your glucose levels are well above 6mmol/L, and the readings will jump around instead of a constant unbroken line. The only thing the G7 improves upon from the G6 is the application process, which is a bit simpler, and the warmup period has been reduced from 2 hours down to 30 minutes. Other than those two things, G7 is an overall downgrade from the G6..⬇️⬆️➡️⬆️⬇️⬅️Version: 2.1.0

Frustrating to get going and to keep goingI don’t know why they decided it was a good idea to have it keep prompting you about notifications being turned off. High and low alerts should be enough. Every time I open the app to update my meals and carbs I have to hit dismiss multiple times. Frustrating. I definitely prefer the other glucometer sensor over this one..Qub3dVersion: 1.12.0

Annoying and UnreliableWhere to even begin? First, the alerts are incredibly loud. Not everybody within 5 metres of me needs to hear them. Slightly alleviated with an Apple Watch, but only barely. Next, almost all of the alerts show up twice, for some utterly baffling reason, and whenever you open the app to log that you've decided to heed its warnings, you have to mash through multiple boxes telling you what you already know because of the alerts that split your ears and everyone around you know what a pitiable wretch you are. All of this would be just about excusable if the monitor itself was any good, and much of the time, it's entirely fine. However, I have been using this product for three months, and FOUR sensors out of the ten that I've used have failed on me, the latest two separated by only two days. That's a 60% grade, just barely above failing. I don't want to keep going back to the pharmacy and being woken up at 3 AM with the news that yet another of the products I trusted failed. My own pancreas has failed me; the least I could ask is for a product that helps me stay alive to not fail me too. Drastic improvements are in order..JoeBamaBamaVersion: 1.12.0
