Dexcom G7 Customer Service

I’ve been reading other reviews about problems that I’m (thankfully) not experiencing. The G7 is my first cgm and I’ve been using it for about 6 weeks. In that time, I’ve had it lose the connection a couple of times but otherwise it’s been solid. Far fewer problems staying connected than, say, my AirPods. Zero problems with the app crashing or sending incorrect alerts. The biggest issue I’m seeing is inconsistent readings between sensors which is obviously a problem. In terms of usability, I agree with many suggestions that others have made. The fact that I can’t click the graph to see the reading at a point in time is egregious. (It’s possible to get the number but not easy or obvious.) same goes for being limited to the last 24 hours. The Clarity functionality should be integrated and I should be informed about trends without having to piece it together myself. It’s odd that all of the logged events appear below the chart if you rotate the phone to landscape but not in portrait orientation. I get that there may not always be room to show everything, but there are plenty of established patterns for condensing markers to fit the available space. That I can only enter total carbs for a meal makes no sense. Not even a label so I know what I ate? I’ve been entering food as Notes so I have control over what gets logged. While G7 is not perfect and acknowledging that I haven’t used G6 as a point of comparison, please don’t let the reviews discourage you from getting a cgm. This one or another. It’s a complete game changer compared to doing finger sticks.

I love my Dexcom. I don’t like the suggestion of arms as the only location for sensor placement. Hopefully it is just a suggestion and there’s no reason you can’t use the abdomen. Honestly it’s just a failure of Dexcom to not do studies on abdomen placement. My current issue is my iPhone is alerting twice for low bs and stuff. It’s as though my h6 is still active and both g6 and g7 are alarming one after the other. I got a new phone so I deleted Dexcom all the way, searched to see if any other Dexcom programs were on my phone (no) then reinstalled Dexcom and it’s still happening. Also still having very random sensor failures and, even though they will replace them, it is more problematic to have them fail day 2 of a 15 day sensor period. Also no one tells you they can fail at a super high blood glucose. Mine read 350 when it was really 600- yes my family had been checking it as I was admitted for keto acidosis (thank u Jardiance.) Before you berate me for poor glucose control, I had normal blood glucose with two Dr appointments. All lab tests were normal, but something was gravely wrong with me. Supposedly rare, so they don’t warn about euglycemic ketoacidosis. 350 bs came later when my body finally collapsed. Acidosis kills off sensors?

It helped me improve my sleep pattern . Waking up at 3am had something to do with hypoglycemia. I was first upset when the phone woke me up when my glucose fell under 70. But now I think it helped me realize I needed some behavioral changes and that I actually have some control of the app alert . By keeping notifications on, turning sound alerts to silent I can view the alerts on my screen as banners and it is much less annoying. But I also started to eat light healthier snack ( night time digestive) before bed and it improved my sleep patterns. So thank you. Maybe app could help users to feel more accepting of the app by suggesting banner alerts and give options to people suggesting use banner alerts instead of sounding scary night time notifications. Rudely awakened has something to do with why this app get such low review rating. An addition: annoying critical alert comes on when the web is unstable too often/ all night long, please make that also an optional banner notification. Unstable network should not be reason for waking users up, upsetting our whole night of rest.

Long time user of FS Libre. Hated that one. Love the Dexcom G7 because I don’t have to scan anything! I never have to calibrate it either. I’ve checked and continue to after putting in a new sensor and it’s always within 3-5 points of finger sticks! The alarm functions are great too! I’ve had 3 occasions where the critical low has gone off due to my forgetting to eat. When I got cortisone shots in my knee I set the high alarm to 180 so I know when glucose is getting high. Allows me to continue getting injections when I need to and not worry about cortisone raising me into the 400’s! Life saver for me. I bought a receiver because my ins insisted. Never used it as the iPhone app works seamlessly even with all the updates Apple puts up. The sensor is easy to put on. Only one issue with the overpatch and that was user error. I put it on upside down the second time. So I didn’t wear the overpatch for that 10 days and the sensor was fine. The tape on the sensor holds great! Very easy to pair the sensor! Tip: Go to settings, Bluetooth, and remove the old sensor before pairing the new one. You also should choose stop sensor or replace (I forget which it’s called) so that your phone knows to forget the last sensor. Honestly, I seldom use the clarity part. I don’t log my meal carbs. I count my carbs but really after 40 plus years as a diabetic it’s second nature to know my carb count and how much to inject. I do note my meds though. Insulins of course. Oral meds including vitamins just go down as meds. Ozempic as Oz. Records the time for me which is the same all the time. Not sure what I’m forgetting but love the Dexcom G7! Anyone who is having issues is probably overthinking or its user error. This device is perfection! Use with confidence! Make the best choice! It’s right here!

I have used the Dexcom CGM off and on (depending on insurance coverage) for the past 6-7 years. I love everything about the Dexcom, including the quick response when submitting a sensor failure report. I love the ability to set different alarm parameters for daytime as well as nighttime, including my preferred threshold for high or low glucose levels. The main issue I have with the current Dexcom app system is that even though I have the alerts set with snooze on for 1 hour, I will receive alerts every 5 minutes for up to 30 minutes at various times day and night. It’s happened while driving, while in meetings, and at night when I’m trying to sleep. I’ve attempted to reset my alert settings, but I still have the same issue. This has occurred with many sensors over the past several months. I am unsure of what to on my end or if this is an app issue. Other than the above issue, I highly recommend the Dexcom CGM. I would rate it a 4.5 but I can’t rate half stars. 😆

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!

In reading other reviews, I have no doubt that some people experience issues. But the app has worked wonderfully for me and for other family members using the G7. 1. I find it more accurate than the G6. 2. The short 30 minute warmup is a great improvement. 3. Being able to put it somewhere other than the abdomen is an advantage for me. As I read some of the complaints, I cannot help thinking that “the app ALREADY does that”. But not in the rued of everyone else. Here’s my situation, and I know that not everyone of in the same situation: 1. I use a phone that is identified as compatible. 2. I keep phone (an iPhone) updated to the latest version. The only time I have needed to wait to install an app update has been the annual full version update and I waited for the OK from Dexcom. 3. Yes, I live in the United States. It sounds like Dexcom can and should do better for people in other’s countries. 4. I have used the available options in the Alerts to customize the frequency, sound, Andrew volume of apps. Some Alerts even give the option of limiting the setting of a phone that is set on vibrate. 5. I have used the already available option to set up a second profile — which is highly customizable, and which allows setting the time in which it is functioning. Although I use this at night I see no reason that it could not be set for work hours with softer or silenced alerts. NO app can have all the features that individuals think should be present. The G7 has a clearly stated purpose and it is not an all- inclusive diabetes management tool.

I appreciate the reviews and improvement suggestions for the app. However, as someone who was diagnosed with diabetes within the last 6 months and who has only been on a cgm for 3 weeks, I’m gearing my comments towards those who are trying to decide whether they can afford the sensors even with insurance. It caught my 2 dangerously high readings after eating meals I knew weren’t great but had convinced myself were okay. This last week, it caught multiple dangerously low readings both every night and every day. Those seem to be due to interactions between 2 drugs that don’t usually cause problems together. If I had been using a finger stick, I don’t think I would have been aware there was a very serious problem. In fact, my levels might have looked great at the time I tested. So, yes, I would say the sensors and app are necessary for true diabetes management and safety-at least at first.

I like the Dexcom G7 app overall. I’ve been using Dexcom apps since the first one in the G5. This one does what it says it will do. It’s a pretty simple app overall. But there are a couple annoyances I have. First is that Dexcom removed one of my favorite features from the G6 app, which was the ability to put your phone in landscape mode to see a landscape graph of your blood sugars over various time ranges that you can click, and then DRAG YOUR FINGER along the graph to see a close-up reading of your blood sugar at that time. This was very useful and allowed you to tell exactly what number you hit and when. Now, it’s just a chart that you can’t interact with. And second, no matter what I try, I cannot seem to get “direct to watch” to work. Maybe it’s a skill issue, but I have the newest generation Apple Watch and am following all the instructions, and it simply does not work. Other than those annoyances, this is a pretty good app.

Love the Dexcom G7 and the convenience the device and app offer, over finger pricks! Been using Dexcom for over a year and the biggest complaint would be towards the alert features. Why do the notifications trigger the absolute loudest and most obnoxious alerts, when I’m using my phone and can see the notifications?! Let me customize alerts different when my phone is locked versus unlocked maybe. I also dread when my Apple watch is charging and my sugar is low or high, the alert tones man, THE ALERTS! They’re so repetitive, let me acknowledge it and then not alert again for 5 mins, rather than rapid fire ALERTS. Getting readings directly to my watch is amazing, fairly new feature - when it actually connects. Update - thank you developers for the tips on alert setup. Having to acknowledge them in the app is the key. Which is inconvenient, acknowledging from a notification would be paramount.

Le Dexcom g 7 est efficace. Le logiciel est facile à comprendre et à régler. J’ai hâte au G8 qui sera plus petit et qui offrira 14 jrs au lieu de 10 jrs de fonctionnement.

Works good, setup is easy, but there are a couple of things that could be better. First off, why no dark mode? For people with poor eyesight, white letters on black is much easier to see. Second, why not show the +/- change since the last reading? That info is vital in trending and much more accurate than an arrow that often points the opposite direction to what your previous reading actually was. Thank you.

Have been using this for about a week. I don’t understand the bad reviews it’s been great so far

The 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?

This 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.

Recently 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.

I 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!

The 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.

I’ve been using the Libre 3 for six months and tried this Dexcom G7 . I have a mixed comparison review. What I liked: it seems more accurate once it calibrated over three days. The score more closely resembles my blood monitor by about 12 points. The Libre sensed wildly high glucose spikes causing a lot of worry and stress. When the Dexcom was so much lower overall , I purchased a blood monitor (I’m only monitoring for information and diabetes prevention due to family history, not actual diabetes). The blood monitor verified the more neutral glucose variations of the Dexcom. What I don’t like: 1. I really dislike the app’s history graph. It goes all the way up to 400 and my zone segment is minuscule, making it impossible to know what my numbers were other than the one real time number I see at the moment. Why do they not allow this to be adjusted? Why do they not put any numbers or lines in the zone? Why can’t I adjust my zone preferences? 2. I lose about 2 to 3 days with ridiculously low readings with each new sensor application. This causes alarms going off every five minutes to the point where I have to turn off my phone. I am unable to turn off the critical alarms. Since the sensors are only good for ten days, this means I lose about 30% of my sensor time per month. Not acceptable! 3. As mentioned before, I cannot turn off critical alarms so I have to turn off my phone every night. When I sleep on my side, the sensor reads much lower than it should, alarms waking me up all night. 4. Only reads every five minutes. The Libre reads every one minute. That’s a long time to wait if you have a concern and are staring at your phone. 5. Seems to drain my battery faster than the Libre even though it reads less often. 6. Price is higher.

Overall, I’m grateful that the technology exists…but the app experience can be greatly improved. 1. If I go low, I get two notifications within seconds of each other. 2. After about the 6th day, the readings become spotty every single time…several hours of no readings, then it comes on again just before it’s long enough to say it failed. 3. Several times it’s been wildly inaccurate…I mean over 100 off and heading in the wrong direction. 4. Lastly, when it fails and I to submit the complaint through the contact us…why is my info not recorded just from being linked to my account? I shouldn’t have to retype my name, my email, my phone, my birthday every single time…it should just be linked to my account. No one else could be using my Dexcom that’s hooked up to me, so there’s no reason for that. The only possible explanation is that they want to make the complaint process difficult so people are too annoyed to do it, so Dexcom won’t have to send you a free one when their device failed. If that is the reason, it’s a pretty bad look for them. Some of these things are hard to improve with the technology and accuracy, I get that…but the notifications and complaint process should be fixed immediately.

Do 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.

The Dexcom G7 iOS app crashes every night. Not most nights; every night. Reboot, reinstall, etc does not fix it. The reason for the crash? A runaway loop that the devs can easily hunt down if they bothered looking at crash logs. Nighttime is when this app is needed the most to avoid critical lows. Unfortunately this app simply is not trustworthy nor reliable. If it can’t stay running overnight, what’s the point in hoping that Dexcom will maybe someday fix this? It hasn’t gone without crashing overnight for over a full calendar year. I’m done being patient, Dexcom. Your software affects peoples’ lives and your lack of attention to stability and reliability is astounding. I’ve used the G5, G6 and now G7. The theme of unreliability and the disconnect between end users and the company’s executives has been the common thread throughout each of these products. None of us use your products because we enjoy the dilemma of trying to find a truck big enough to haul profits to the bank. We use your products in order to live our lives. The fact that I’m staring at daily crash logs and can point my finger at “this is what’s causing my G7 app to crash” tells me several things about Dexcom, none of which are positive. I don’t expect a fix or a response, and I’m done being patient. I’m done with Dexcom.

I've been a user of dexcom products since the G5 days. I can confidently say that out of all the systems G6 has been the most pleasant for me. The pros of the G7: It's comfortable and small. The grace period on the system is nice, and the 30 minute startup period is awesome. The cons: I have found that most of the time it just frustrates me. The constant alarms with false lows are horrible, (I used to barely ever have to calibrate my G6) and when i do calibrate the G7 it doesn't take. It most often shows false lows in the middle of the night while I'm asleep and I find that it's hard to sleep peacefully with alarms blaring off. I thought I could chalk it up to false lows due to pressure from laying on the device but my doctor told me that the design of the new sensor should reduce that problem. I also dislike that I have to re enter my codes into my pump every time, I wish there was a way to have them sync up easier like when my transmitter would automatically start the session on my pump. Overall I'm finding the transition to using this new device difficult, annoying, and definitely not easier than the previous system. I wish I could continue using the G6.

The signal loss notifications, and really the notifications in general have gotten entirely out of hand as of late. The ones that are critical lows/highs or rapid falling or rapid rising: those I understand… but they do not need to be back to back every 2 minutes.. it already told me I’m 78… I don’t need to hear it immediately again or 2 minutes later every 2 minutes.. like please, at least have a way to shut off the incessant alerts if we wish to do so. Not just turn off all notifications.. also, the main reason I’m annoyed is again, the signal loss alert that goes off constantly. Also!!! Before recently, the critical notifications would make noise but not interrupt actions on the phone, now all the notifications, critical or otherwise, interrupt all actions on the phone. Annoying, unnecessary. Please, this is making my life harder not easier. I’m aware that was long winded, but I wanted to make sure I covered all my bases. The app was great before, now I literally hate it. It would’ve been so much more productive to improve reading accuracy or signal stability when Bluetooth hasn’t been deliberately turned off. Thank you.

It 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!!!!!

This app is lacking in useful features and feels weirdly laid out. I feel like I had much better access to useful information using the Freestyle Libre sensors and app. The biggest annoyance, to me, compared to Libre is, when you log a meal or snack or insulin on the Dexcom app, it *does not* add an icon on your glucose graph/timeline to help identify when you ate or took insulin. This no-brainer feature was available on the Libre app though, and was obviously very useful to easily correlate when you are with the effect it had on your glucose. You can find this info on Dexcom, it’s just not simple. On top of that, Dexcom just updated the app and now the home screen only displays your glucose number and the graph. Whereas before there was much more info at a glance. Now you need to switch to different tabs in the app to get the same information you used to get at a glance on the first screen. It’s as though they’re trying to get their app engagement numbers to increase by making you hunt for info, instead of making the app useful. I can’t wait until I have health insurance that covers Freestyle Libre.

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!

When blood sugars are high or low, the app will notify you over and over again until you silence it. You’re only alllwed to silence it for 6 hours at a time, which is ridiculous. The notifications lag your phone, pause any media temporarily, and you can’t turn them off no matter what you do! The app will stop working completely if you silence the notifications or turn them off with Apple settings. App is also poorly coded. Every time your sugar is high or low, in the app it will have a pop up in app stating it’s low or high, when clicking over to the other tab to go mute it, it’ll pop up again and bring you back to the main menu, making me need to spam tap the notification tab until it stops needing to notify me (usually after 2-3 “ok’s”). Actually almost curbed my car once cause it was interrupting my phone call and I had to get it off, takes so long to get to the screen to turn them off cause of this. Considering the fact that anyone who uses this app has to use it for the rest of their lives, and every single day, we should have FULL ACCESS to notification customization (mute FOREVER, Turn off notifications TOTALLY, dark mode, etc).

I never write reviews for apps but I’m making a special case because oh my god this app is insufferable. I moved from the G6 app and this one is so much worse. The UI is completely broken, buttons break constantly, but the kicker is how it handles alarms. When you clear alarms, every time there is about a 60% chance that it just does not recognize you cleared the alarm, and will continue to scream at you every 5 minutes even though you have recognized and cleared the notification. On top of that, unlike the G6, the G7 very often ignores the “silent notification” rule. In case you are not aware, the G6 app would give you a silent heads-up about an alarm, then if you do not clear it, it will give you a full alarm with sound 5 minutes later. This app will very often just ignore the silent alarm and go full DEFCON 1 on you and just freak out immediately. The amount of times this has happened in the middle of a class or test is ridiculous, and completely embarassing when everyone turns their heads to figure out where the full volume alarm came from. How this app got cleared past QA is beyond me. Dexcom, do better. Your G6 app worked 500 times better than this.

I was recently switched to the G7 from the Freestyle Libre and let me tell you that the Freestyle is superior in almost every way. The only advantage to the Dexcom is price. I don’t like that the Dexcom is only 10 days vs 14 for the Freestyle. I get warnings about it not finding my sensor even though I’m a couple of feet away from my phone. But other times I’m across the house and there are no alerts when I get back to my phone. The app isn’t as good either. It gives you a 12 hour “grace period” to put on a new sensor. If you forget when the time limit is up it blasts you with a loud alarm. You can only cancel it for 5 minutes and then it goes off again. WHEN I CANCEL AN ALARM I EXPECT IT TO STAY CANCELLED. One morning I just wound up deleting the app to get it to stop. The Freestyle gives you a count down to the number of days left and on the last day it tells you exactly how many hours you have left. I know what’s going on and how to manage my diabetes I don’t need this app forcing itself on me. It needs more settings so I can set it up the way I want. All things being equal I would absolutely recommend the Freestyle over the Dexcom. Even with the higher price I may still go back.

This is a very good app for tracking sugar but it needs significant improvement in the way alarms are tracked. High alarm goes off, okay fine, acknowledge alarm, take insulin. 2 min later high alarm goes off again with the same sugar reading, acknowledge again. Process will continue non stop with nearly identical sugar readings. Yes I know I'm having high sugar, even the modern fast acting insulins take some time to work. There really needs to be a way to say okay, I've recognized the alert, I've done what my doctor told me, please tell me if it’s not working in like 30 minutes. If not it just becomes an annoyance. The other night I had it go off every few minutes for an hour straight because of a 263 sugar. Because of the danger of going low at night, I take less insulin in these cases and I've been diabetic for so long that my sensitivity is not what it used to be. Telling me over and over again literally minutes apart the same thing is not helpful. I love not having to stick myself but the never ending alarms are driving me nuts especially when they occur within minutes of each other. If it’s low that's one thing but highs are different for my body.

As a type, one diabetic new the new CGM is really bad. It barely works falls off all the time and does not work overall if we’re being $150 it does not work. It is not worth it. I mean it’s cool that the warm-up time is only 25 minutes, but I’d rather be at two hours and work like I don’t know why it doesn’t work and it really makes me mad because they said it was supposed to be like the best one when I think it’s worse they never work. One of the times it didn’t work it didn’t read for a straight hour then when it finally did, it just said low and I’ve had this problem multiple times or just straight up doesn’t work and won’t give me anything like fix this, please I wanna switch back to the G7 but the app is really good. It’s a nice format and I feel like I can access everything easily but the G6 does not work well. And a couple of times. It said I was like 160 but I was really 45. So I went really high and didn’t know and when I finally checked myself, I was 400. I was just like how do you read that far off and the reviews on this are way lower than the Dexcom G6 like isn’t that crazy? You guys worked Thomas for a very long time and the older one is better. like what happened this is outrageous.

I’m a type 2 diabetic. As I do need to use the Dexcom because it’s not predictable, I also don’t need it on 24/7 either. And I absolutely hate the changes you have made recently! When I take it off because I can’t do what you say we can by going swimming and stuff when it’s on, it falls off immediately and doesn’t stay on. So when my 10 day sessions end, I like to leave my Dexcom off for a few hours to maybe a whole day so I can get in the pool and enjoy myself. But now that you’ve made these changes and it alerts constantly that terrible unsilencable noise I can’t do that anymore. I have to completely delete the app between every session now because it won’t stop doing this terrible noise over and over until it gets its way and I put it back on. Do you not get how frustrating that is that I have to completely delete the app now and then go through the entire set up every single time I want to put one back on! I really wish that you gave us the option to silence it completely when we want to go without one without having to completely delete it every time. You have no idea how angry this has made me! Almost makes me not want to use this stupid device anymore!

I 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.

I love this app so I can see my blood sugar in real time. It has helped me control my blood sugar so much more. Not sure exactly why that is but I guess seeing it all the time makes me aware of it. The main problem I’m having and keep having is in the app. It says that notifications aren’t allowed and I need to allow the notifications or I won’t receive anymore notifications. That could to very bad consequences if I’m not notified whether I’m having a low or a high. The thing is that I NEVER turned them off. Evidently it’s a bug or a glitch of some sort. The only way to get my notifications back on is to either power my phone off and back on. In the event that it doesn’t fix it then I have to uninstall the app and reinstall the app. But I don’t like doing that because it messes with the numbers that it uses to come to the average blood sugar levels. Although, I have been told that all the info is still there but located in my apple health or clarity. Please help me fix this issue. I’m so frustrated….

Fairly solid when it first launched, I didn’t notice too many issues. But firstly, it constantly loses connection to the Dexcom, especially when you’re walking an extended period of time (which is likely just their trash Bluetooth, albeit this happens with every sensor I’ve ever used- at least the G7), thankfully the omnipod app will give an alert if it hasn’t received readings for AN HOUR (kill me)…the Dexcom seemingly doesn’t alert you, which is an oxymoron in itself. Secondly, whatever the latest release is seems to backlog every time you have a rate of change(?). Which is extremely annoying to get push notifications for…if my phone isn’t vibrating every few minutes 3-4x in a short time span, when I unlock my phone I get banner notifications repeatedly until it’s shown me each change its detected and logged (this won’t happen if you turn all but critical alerts on which is fine, but as a software dev it’s quite irritating from a UX standpoint). Overall it does what it needs to do, the algorithm doing autocorrecting really needs some work so it’s more proactive than reactive though.

I switched over from the G6 to G7. So far the worst mistake of my diabetes journey. The thing usually gets torn off after 1-3 days due to the device being a cakewalk to rip off from the sticker. Along with this, the Dexcom itself has a rubber-like material which generates friction, making it make doing something as simple as turning over in bed a hazard since the thing is very likely to get torn off. (true story for me unfortunately, it was 4am and I was not happy.) You would think that the G7 would be better due to it being newer, so the technology is better, but don't let that fool you. The G7 also has issues with connecting to my pump (Omnipod 5, which is G7 compatible) The only Hail Mary this thing has is the readings seem to be more accurate than my G6. It is also not so irritating on the skin, at least for me. Both of the mentioned things are useless though when the entire thing is dangling from your arm because you accidentally bumped it into a doorframe. Unless this somehow sounds better than what you currently have, I strongly recommend you do not get this. If the G7 is your only option, I am so sorry and I hope that they become better over time.

I have been a diabetic for over a decade, and have yet to come into contact with a platform more annoying and uncustomizable than recent iterations of Dexcom apps, and more recently, the Dexcom G7 app. Personally, I absolutely HATE notification sounds. Anything that gives off random sounds for information that could easily be communicated through a vibration is hair wringingly annoying to me. In the middle of the day, when I can feel how low I am, an alarm that notifies everyone within a fifty foot radius that I am a diabetic and low is just not ok. When I am asleep, that is a different story. However, these unmutable, maximum volume “critical alerts” for when my blood sugar is 55-60 is, in my opinion, unnacceptable. You cannot turn these notifications off without the app proceeding to not work. Its a different story when my blood sugar is <50. Thats much more urgent. But these ear piercing and ANNOYING alarms play all the time and without cease. I need to be able to turn these alarms off, as it treats a minor low as if its the worst thing that could happen to me while Im already trying to take care of it. Whats worse is that the G7 constantly pegs me as being much lower than I actually am. Not sure why, but fingerpricks tend to have my blood sugar 20-30 units higher than the G7 has me at. So not only do these alarms constantly go off, but they are wrong more than half the time. Heaven forbid I am taking an exam or something and this alarm goes off in the middle of it for a blood sugar reading of 60. Yes, you can silence it for 6 hours, but shortly thereafter, these awful alarms can continue. 6 hours is not enough for me. Make the critical alerts actually critical, not mundane and regular.

If I had to see the history of my previous readings from previous day, I cannot do so in the app. I can only get 24 hour view. For reports I have to go to another app which generates a pdf. I want an interactive app where I can go to Friday of last week and see how my glucose reading was at a specific time. Not a report. Very non-intuitive interface. Why would I generate a reports in pdf? Great for sharing to medical professional but I want an interactive experience where I want to find how the food I ate last week impacted without running a report in a different app. The app requirement team seem to be a porting team that ported old functionality to an app! Essentially converted a desktop application to a mobile app. Need to improve this to be one app which can store the data in my cloud or in device. Not an intuitive design at all. The one star is for the existing graph. But for rest of the interface I would give a negative five star. Needs a complete revamp. Libre app has all these features and I can go back and forth in time seamlessly. Summary, History, Reports all in a single app. I wish the Dexcom team, esp their designers spend a week on Libre and see what is missed in this app.

I never update my apps unless i really need to and a few days ago the dexcom app suddenly said it wasn't compatible with my phone anymore so i panicked and updated it thinking it would fix the issue (it didn't and it fixed itself a couple hours later somehow). anyways i absolutely should NOT have updated the app or i at least should have looked at the recent reviews first. there is a very important issue going on in the updated version that no one seems to care enough to fix. the app won't stop crashing!!!! when i close the app manually i get a notification telling me to open it because i won't get readings otherwise, but the app keeps crashing on its own in the background now and i have no idea because i'm not getting these notifications! i keep going hours on end without any readings which is very concerning! if it were any other app having bugs like this it wouldn't be such a big deal but people literally rely on this for their lives for god's sake!! i constantly go low in the night while i'm asleep and yet i woke up this morning to an hour and a half of no readings because this useless app decided to close itself for funzies while i was sleeping. when do you plan on fixing this detrimental problem??? it's apparently been ongoing since JANUARY and there has been no effort to solve the issue. just replying to reviews telling them to contact support but when you actually try there's no way to type out the issue you're even having so it's pointless. not to mention it's an app issue in the first place so what would patient support even do? i am so upset that i updated the app right before i have multiple vacations where i'll be far away from home and my mother will be worrying constantly because it's going to keep losing signal. fix your app. people could die.

* update: I have been using G7 and there are some features I really like but I still get the lost signal alerts even when my phone is on my physical person. I think the range is more like 6-10 ft. Not 20. At least 4 of the 9 sensors I got with my last refill failed or didn’t stick. They do not last 10 days and this is a costly product. I have gotten over-patches and they help but then you have this disgusting tape visible all over the back of your arm. Please fix these issues because this product is essential for me to maintain healthy blood sugar with minimal medication. Very disappointed that after using G6 for many months successfully on my abdomen they introduce an “upgraded” product and don’t even disclose that you can no longer install it on your abdomen. It’s literally nowhere in the paperwork. It doesn’t even say don’t install on abdomen. However, if you do install on your abdomen it voids the warranty and “may not work properly.” This is fine for new customers but completely disregards existing clients that are transitioning from G6 to G7. I don’t like to have a medical device showing on my arm where I have to explain what it is every 5 minutes. Or if I’m at an event and wearing a nice outfit but have this device on my arm. So now I’m stuck with all this product and I either have to use it on my abdomen and void the warranty or I have to have it on my arm. Update: I just went ahead and used the G7 and I am having the same issue with frequent loss of signal as reported in other reviews. Early this morning I got a lost signal alert while I was still sleeping in bed and my phone was right next to me on my bedside table. I am also getting the alerts multiple times a day even when I am in the same room as my cel phone.

I have been using Dexcom for the better part of half of my diabetic life. In the past couple of years, it hasn’t failed me, neither the device or the app. However, recently it has been awful. In the morning, I will look at my blood sugars and see what they were through the night. It seems to work just fine. Because of how my day to day goes, I’ll usually turn notifications off midday as to not disturb anyone around me. After I do that, I don’t get any notifications at all. That should be a good thing, but it’s not. It won’t even alert me if my blood sugar is going high or if I am low. I have to go in to the app to find out that it has “lost signal”. Every single time? Something is wrong with the app. It may be because I still have the iPhone 8 and it’s losing compatibility, but as a diabetic this is dangerous and horrible for my a1c. Granted, I should be more on top of it, but that’s what these apps are supposed to help with, not hinder. If someone can walk me through how to fix this, or tell me if it’s my doing that is messing with this, that would be much appreciated. For now, I’m going to have to stick with a different app for readings.

I 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.

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. Thus, submission is impossible from my iPhone 14Pro with latest iOS.

The 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.

Just switched from G6, which wasn’t phenomenal, but the G7 iPhone app is AWFUL!! It alarms EVERY THREE MINUTES if my BG is low or high. I click OK, but it goes off again. While treating a low, I don’t need critical alerts going off every 3 minutes!!!! I had to turn off the rising high, high, and I’m about to turn off the falling lows, and lows. But then what’s the point????!!!!!!! Horrible app developers!!!!!!!! F rating!!! You have GOT to fix this!! There’s a snooze for 30 minutes option for a reason…I need time for treatment to WORK before you remind me again. Critical alerts also should be able to be silenced no matter what (like I get to say, yes acknowledging, but I need 20 minutes… or 30… or whatever). As an adult living life, you’ve added stress (yes, alarms are STRESS) to things that can literally wait a few freaking minutes. Have you heard of ALARM FATIGUE??!! Maybe you have, but until I get to take over YOUR phone and alarm whenever I feel like OVER and OVER at ear-piercing pitches, you are just a poor excuse of an app developer who doesn’t understand people with disabilities trying to LIVE. Please respond when you’ve fixed this critical error.

I 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.

Tracks glucose well, notifies you if you go too low, but does a LOUSY job of keeping your recordings of insulin use. My endocrinologist thought I was not taking insulin as I should, and I had AND HAD RECORDED IT IN THE APP AT THE TIME. Next time I looked, those most recent entries had DISAPPEARED, and I have had to reenter them from memory. This is NOT a new problem; I have used the app faithfully for at least a year. It happens irregularly but about DAILY. Also, I no longer record anything in its Notes, which I had tried putting additional useful data in for my endocrinologist, because 100% of that data disappears. It’s kept me alive with timely notifications (and I can and do occasionally drop 100 points in 5 minutes, which is how often the app checks your blood glucose), so I have to be careful not to go too low when I’m asleep. This does work to a degree, but is a VERY FLAWED solution. I am alive because I have been alert enough to get up and get sugar into me immediately after low glucose alerts down into the MID 40’s at times between 0300 and 0600 when I’m asleep. USE WITH CAUTION.

I love Dexcom but not the G7! Since upgrading from G6 to G7, I can NEVER make a full sensor last the 10 days. I am an iPhone 16 user with Omnipod 5. I delete old sensors before the new sensor, I do not have the low power battery on, I have the G7 set up for when a Focus is on, my phone and my Omnipod receiver are ALWAYS next to me (within the 20 ft range) and I continually receive brief sensor or wait 3 hours alerts. I just don’t understand. I had very few issues with G6. I like the G7 better because the sensor is smaller and lasts longer. I really wish we could also just use our phone as well to do the Bolus or correction so I only had to carry 1 thing. Dexcom and Omnipod need to collaborate better and Dexcom needs to get their sensor issue fixed for the G7. Every time I talk to Dexcom the standard answer is, it’s something with my blue tooth or they don’t have that many calls of people having problems. I know that to be false because many blogs have numerous people that have the same issue. Please get this problem fixed. The numbers are becoming unreliable.

First off, I must say I love Dexcom as a product for T1D. It’s so beneficial to have my blood sugar on my phone and watch and be able to share data with other people. However… I recently upgraded from the G6 to the G7, and have noticed that the app will sound off twice for a low alert (once for the actual low alert) (and then a second time for the “55 within 20 minutes” alert). This is an atrocious change from the G6 app, which would only give one alert for each low reading. With the G6, if I was slowly going low it would give me the regular low alert, but if I was falling quickly towards 55 then it would give me that alert instead. This was great, because I knew just by the sound what I needed to do. Now I get both alarms every 5 minutes when I’m low, and there’s no need for this. It just means I’m constantly listening to 2 alarms every 5 minutes when I’m low. It also means I can’t just use the sounds of the alarm to understand my levels and actually have to go and check how fast I’m falling to verify what the response should be. Personally, I feel like the G6 model of only one alert for each reading is needed, and it actually was more useful since it gave me better audio information because I could listen to which alarm went off and know what to do. Hopefully this gets fixed soon because it’s a huge pain point with this new app and actually deteriorates the value of having different alarms for different fall rates. Separately, the widget functionality for the G7 is significantly worse than it was for the G6. The widget never shows real time data and usually only shows data up to 20 minutes previous. To view the most recent data points requires actually going into the app. Obviously this isn’t a major, major concern and is just a ‘nice to have’ item, but why even have the widget if it doesn’t show current readings? It’s basically useless for quickly checking your levels.

Dexcom 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.

I’ve used Dexcom for over 15 years and loved how each model was an improvement, until the G7. The G7 is absolutely terrible. The blood sugar readings are incorrect so often and at times up too 100+ points off, so it’s very dangerous. The app itself, even though it has potential, is always giving me a np readings alert when it is actually working! I’ve gotten almost 10 this morning already. Sometimes there aren’t any readings even when my phone is only one or two feet away from the sensor? I pretty much demanded to my doctor to go back to the G6 because I’ve had zero confidence in the G7 for quite some time. I thought after all this time that the G7 has been out, they would have corrected the multiple issues. To Dexcom, shame on you for putting people’s lives at risk and not for acting in a quick manner to correct all the issues of the G7 all together. Many years of gaining and having trust to have it lost because the company doesn’t seem to care, especially after the several years the G7 has been out.

The watch complication disappears from my watch with every new sensor and requires a bunch of hoop jumping to re appear. Recently the iPhone app has been incredibly laggy, taking more than 30 seconds to load even though I never exit out of the app unless it crashes. Notifies way too much even if you acknowledge a low/high reading in app, but then sometimes doesn’t notify at all for lows or highs even though I don’t have any settings on that would change how alerts appear at certain times. Buggy and inconsistent with Clarity connection and sharing with doctors office. When adding a calibration, it will kick you out and bump back to the reading screen with a delayed “alert” that you are high or low that you need to “ok” before you can go back and calibrate (even when that low:high alert is inaccurate, but it interrupts you putting in a calibration to let you know the incorrect reading you already saw when you opened the app). We pay so much for this tech and deal with so much hassle with the sensors having errors or failures, and this app is an insult to users.

Beware, reinstalling will wipe your 3, 7, 14, 30 and 90 day previous data and you will not have this available untill you reach thise milestones. Dexcom does not seem to thouroghly test this software or updates. There are many loose ends you will discover through use. I wish G7 software was made by Apple or Tesla engineers, but it is not.

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.

This is a much better all round product than the G6. Set up is fast. Apple Watch talks to it without the phone present. I find it to be generally more accurate than the G6. My only complaint is the transmitter is very weak. It has a much shorter range. Loses touch constantly if you sleep on it and even when it’s it inches away. I lost contact twice while typing this and sitting on the couch with my phone inches from the transmitter. It really is pretty bad. Hopefully they fix the transmitter issue. If they do it’s 5 stars for me.

The iOS app on iPhone is decent, but no end of problems when trying to use with iPhone app. Have tried reinstalling app on phone, removing & re-pairing, rebooting watch. Just useless.

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!!

Don’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.

Sensors are great; but app is a poor accessible app with many issues!

I don’t know what kind of update they did, but now anytime my blood sugar is even a little bit high. It’s popping up as a notification that’s a critical alert when it never did that before. When I try and put it on silent mode for a while it doesn’t actually go on silent mode, it keeps giving me notifications. Like I get it my blood sugar is not in target even the fastest acting insulin needs time to work.

Having the G7 constantly send notifications defeats the purpose of CGM. Had to silence. Getting an unnecessary notification every 2 min - unacceptable! Please fix this app.

Yall what is with this critical alert thing in the update??? for super low lows yes keeping and same with super high but when my blood sugar is 10.1 why am i getting a critical alert??? quality of life with that is 0 when my phone sounds like a fire alarm, worst update of my entire life

Come on dexcom, this is embarrassing how antiquated the app is. There are so many obvious updates that need to happen that I could spend 20 minutes listing them all.

Unfortunately, the direct to watch feature no longer works. It’s the only reason I bought an Apple Watch. What a waste.

Addendum 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

So many people have been complaining about the continuous spinning wheel when attempting to log in. How many months must we wait until it gets fixed. Come on! Get on with it!

Latest update has caused high glucose warnings to become “critical” with no way to change it back. This causes all media or phone call audio to suddenly and without warning BLARE AT THE HIGHEST POSSIBLE VOLUME IN YOUR EARS OR FOR EVERYONE ELSE WITHIN EARSHOT. This is completely unacceptable that a company this big can’t properly beta test updates before unleashing them on customers.

A really clunky app wrapped up in an iPhone app. To me this is some legacy app that has been popped inside iPhone app ecosystem. There’s nothing native about it. This app is designed just for people with diabetes, not people tracking health metrics and what foods cause what. The on boarding is really bad. It has an embedded capture spam solving puzzle. The charge is very basic. You can’t interact with the chart you can’t do thumb zoom go back in time or anything else.

The app is fine and helpful. But it forces me to activate notifications and critical notifications to work. I don’t want this! I am an adult and can deal with my blood sugar. The worst thing is being blipped at continuously with no way to turn this off. Remove mandatory notifications and you get my 5 stars

If I wanted to make diabetes management intentionally more difficult, I’d make an app exactly like this one and have healthcare providers push my subpar product. It’s sad that this is what we are stuck with in 2026. The app is glitchy and inconsistent, and the watch is even worse. I had really hoped to be able to leave the Dexcom receiver behind, but it is the only thing that reliably connects and alerts with the unreliable G7 sensors.

Not very good ,buggy with apple watch

I was really hoping this device would help me monitor my glucose more confidently, but the readings have been very inaccurate. For example, my fasting blood sugar was around 90 mg/dL, but the G7 was showing 127 mg/dL. Later, when my blood sugar was around 100 mg/dL, the G7 showed 75 mg/dL. I calibrated it multiple times, and it only seems accurate for a few minutes, then it goes back to giving wrong readings again. This is very frustrating and stressful, especially because glucose readings are important and people rely on this device to make health decisions. After using it today, I feel very disappointed and honestly cannot trust the readings. I expected much better accuracy from a device like this. I would not recommend relying only on this device without confirming with a finger-prick glucose meter.

30 min warmup and grace period is great, but there’s lots of bugs. I usually only get 8.5-9 days out of it before it starts crapping out. A low alert will almost always go off again a few seconds after fully dismissing it. If you get a high notification and you’re listening to Spotify it’ll switch Spotify to a random song. This is unbelievably aggravating. Happens often, maybe 85-90% of the time.

Dexcom G7 Review I’ve been very disappointed with the Dexcom G7. Over a 48-hour period, I compared readings between the Dexcom G7 and my Contour Next fingerstick meter, and the difference was extremely large—at times up to 423 points apart. Both readings were taken at the same time, and in my experience the Contour Next consistently showed lower and more believable results. I did some research afterward and found that fingerstick meters like the Contour Next are generally considered more accurate for blood glucose readings than CGMs, which measure interstitial fluid instead of blood. Because of this, CGM systems often require confirmation with fingersticks, especially when readings seem off. However, I expected the Dexcom G7 to be much more reliable given that it is a newer continuous glucose monitor that updates every five minutes. Instead, I found it to be inconsistent and not reflective of my actual blood glucose levels. Overall, I’m disappointed with the accuracy and reliability of the Dexcom G7. Based on my experience, I will continue relying on my Contour Next meter and will not be continuing with the Dexcom system.

The app gets stuck on the loading screen and I’m on the newest iPhone

Please fix the alert system. It has not been designed for adults at all. If a child is using it, the alert system makes sense. But for normal functioning adults, it is just plain irritating. There is no way to permanently silence it. If you sleep on your sensor, the compression causes a low which triggers the alarm. This alarm wakes me up for a false low. It also chirps when you are already aware of the low. The noise can be rather irritating when heard multiple times back to back. Great product, poor app design.

Latest update made all alerts critical for some reason. Go with Libre as these alerts will drive you nuts. Want to listen to music but your blood sugar is slightly high? It will interrupt it. Have your phone on do not disturb at night and above your limit? ALERT Only way to bypass is to set your limits way high completing defeating the purpose.

For context I’m a type 2 diabetic who is safe to not monitor for a short time (not having a Dexcom on the weekend really won’t even impact my health). It allows me to adjust all other setting except the one to tell me to change sensor. I have gotten multiple alerts in the past hour (change sensor in an hour, change sensor in 45 minutes, change sensor in 30 minutes, so on) and they will not quite. I have tried desperately to get it to stop as it is super overwhelming and super annoying. It took until I started actually crying because I couldn’t do a single thing without an emergency notification that rang through every silence I tried for me too look it up and find it’s impossible to actually turn it off. Before this I’d had tonnes of issues with my Dexcom dying and the alerts going off horribly (being in class and my phone going off every ten minutes telling me to put in a Dexcom I physically don’t have with me) I wouldn’t use this app if my health didn’t depend on it, and it’s genuinely getting bad enough I’m debating not using a sensor. Please for the love of god change the notification so I don’t have to make the choice between being the healthiest I can be and physically not being able to do anything without being screamed at. This doesn’t promote health, for me all it’s promoted is negligence regarding my own disability.

Looses signal no history of why your getting alerts terrible graphs

It genuinely boggles my mind how they decide to format and run this app. Each update only makes things worse. In what world would moving the “trend” data from the home page to a different page and leaving a blank space in its place be helpful in any way to anyone? I could give SO many more specific examples but it’d definitely be a waste of my time and frustration because there’s always been reviews here spelling out what users actually want and they’ve just been ignored.

I recently updated the app and now it is constantly sending me loud "urgent" alerts about every 10 minutes as if my glucose was criticaly low but it is perfectly fine. Thankfully I can mute the alerts but they still interupt calls, music and videos. It has been doing that for over a week now

The notifications should only be for low blood sugar levels and very high blood sugar levels or at least let us mute or have it on vibrate instead I don’t need the alerts forcing me to tell everyone that I have diabetes. 😒

Tell me why Dexcom feels the need to alert me of my high blood sugar when I’m 15.0 for 20 minutes and not at my set high bg I take good care of my bg and keep an eye on it well, but I’m human and don’t check my bg every 5 minutes, And I shouldn’t have to as I have a Dexcom that knows I have a high bg but won’t give me my alarms

Crashes when I try to log in to my daughters account but not when i log into my personal account connected to hers

This latest forced priority notification update is driving me insane, I understand if you were a type two diabetic, but as a type one diabetic on an insulin pump, these notifications are more frequent more annoying, and without the ability to turn them off, make me want to switch my sensor brand?

This app is super buggy. Absolute trash for a medical device application. Im often unable to pair my sensors with the app. Its got so bad i now use my insulin pump as my main CGM screen. Dexcom needs to fire a ton of people for this failure of an app.

I’ve been on the phone at least once a week since NOVEMBER with these people regarding the g7. If it’s not a brief sensor issue code it fails on me for no reason. The app just screams at me for no apparent reason with their critical alert function. Why do you people insist on putting these products out if they are built faulty??

App crashes while launching. What a joke app

Low alert is not working even after update. It sometimes sounds d only when I am using the phone. Alerts are brief. We want long loud alerts for lows.

MY BLOOD SUGAR GOES FROM 9.9 to “HIGH” in 6 hours with no warning overnight. THIS APP IS GOING TO KILL YOU IF YOU RELY ON IT. It’s simply amazing how your blood sugar can go from 4.0 to 8.0 in 15 minutes and this stupid app is not programmed to flag that????

This was a really good app from my experience but it just doesn’t work after the new update on March 24, 2026. It just freezes and it hard to keep track of my sugars and insulin.

Impossible de me connecter depuis 2 semaines. Problèmes de serveur encore.

Can’t click the graph in landscape view to see the glucose reading at a point in time like before. Why was this feature removed from the app? Dragging your finger across the graph to see the exact time and glucose value was really useful for spotting exactly when a drop or spike happened, especially when you’re trying to fine-tune pump settings

New app layout is worse in every way. Most importantly, no alarm sounds. I have them set to vibrate during the day however it’s critical at night. This is pathetic and I’m definitely considering switching brands

The sensor and app both work fine. I’m legit scared I’m going to get into a car accident because of the alarm. It will go off loudly while driving and you can’t stop it unless you unlock your phone, go into the app, and press ok. All while driving!!! Many rural roads don’t have places to pull over to do this and this thing is dangerous! I can’t find a way to turn it off without stopping my readings. I also don’t get to sleep anymore because the alarm wakes me up 3-4 times a night telling me my sugar is low. If I eat sugar and also if I don’t, the alarm will go off again within an hour. Every night. This needs to be solved before someone dies in a car accident.

As long as you upgrade your device!!!!! Think it’s time to swap brands when a holes decide your life is less valuable then upgrading to the newest device! GFY dexcom jerks This morning my sugar is dangerously low, 3.1 alarm is going off, it wakes me 6 or 10 times so I check to see what it is. It displays perfectly EVERY TIME but have to dismiss the warning asking me to log in because I’ve been logged out! If I die today it’s quite likely the fault of dexcom!!! App was working perfectly except it would ask me to log in each time I opened the app! I finally looked up my password and logged in to get away from the annoying GD thing and a minute later SUDDENLY it will no longer work with this device!!!!! No warning, not after so many days… just done! ALL BECASE I LOGGED IN!!!! Even though it’s been working just fine for the past few months except that annoying BS about logging in kept popping up. So don’t tell me it WON’T work because it does, just fine! it’s just that you can’t steal personal information as easy as the new devices or something creepy along those lines BECAUSE IT WORKS!! Now I have NO devices that can read my sensor!! Again… at a time it is dangerously low! With NO warnings! Again, if I go into a coma it’s the fault of dexcom. Hope someone has your life in their hands and decides instantly they need you to upgrade your phone or die! EFF ALL YOU dexcom slimes! Once my sensors are gone, so am I!

Critical alerts not sounding!!! 3rd time I’ve woken up myself below 3.5 and my Dexcom alerts didn’t go off. iPhone volume on max and silent mode turned off. What is going on? Not even my high alerts working

If you have the chance to use a G6 instead of G7, take it. Ignoring the benefits of a more secure sensor that won’t fall off as easily, the new app is terrible for keeping track of your blood sugar. Its alarms are either broken or poorly configured. With G6, the alarms were almost annoyingly persistent but they kept you updated. They went through silence settings on your phone and would replay often. G7 claims to do the same but somehow the developers must have messed up the app. Despite going into settings to make sure that dexcom notifications bypass do not disturb and making sure that they have a 15 minute interval between them and experimenting with alert settings to try and fix it, I once had a period of two hours of no alarm. I felt terrible out of nowhere and checked my dexcom only to see my blood sugar had made it to 21 over the past hour and a half without a single alert. Do not trust this app with your health, you are probably better off with an older model or even a libre which you have to scan, because at least those function as expected or don’t trick you into a false sense of security claiming they will send an alarm as soon as you’re high.

Don’t rely on this app the alert you to blood sugar emergencies. Alerts no longer work with the new update and Dexcom tech-support refuses to acknowledge the issue. Use a third-party app for alerts.
