Sleep Time+ Cycle Alarm Clock App Comments & Reviews
Sleep Time+ Cycle Alarm Clock Positive Reviews
Great app!A few things that would improve it greatly: 1) Most important for me would be the ability to change the alarm time mid-session without turning the alarm off! I find it very useful to plan my sleep in multiples of 45 minutes, so if I wake up and by the time I go back to sleep there’s only 30’ left, it would help to be able to add another 15’ or even an hour! 2) It would be nice to be able to edit-say double tap or tap and hold an area on the chart and correct it-like when i forget to tutn it off. There coild be something diff colors) that shows it was edited to preserve integrity. 3) Also if I go back to bed so there are 2 separate sessions for the same night it would be great if they would display stacked. Thanks for a super app!.Version: 5.168
Best sleep alarm everI’ve used this app for around seven years now and it’s the only alarm that I’ll wake up to. I love it because it starts low and gradually gets louder. I hate being woken up by typical alarms that just go right off at full volume. I’ve used this app with the phone laying on my bed (as it suggests for the best reading) and ok my night stand. When on my bed I can accurately tell when I move or wake up or when I’m still and sound asleep. It’s very accurate. I’ve since moved to placing it on my night stand instead because I no longer need to see all the extra data. Instead I now only use it as an alarm and sleep time tracker (to see how long I sleep each night). This is my favorite sleep app and I doubt I’ll ever use another one..Version: 5.28
Works great!!I read previous reviews of this application, and I do not agree. The application does not assess what is going on for you during your sleep cycle. That part is up to you. All the app does is to provide you with the necessary information so that you can assess your sleeping patterns, cycle and how you feel in the morning. With that being said, the application delivers everything that the publisher states it will. I would recommend this to anyone who wishes to assess their sleep cycles as to maybe why in the morning they wake up, and they don't feel all that well. Or they wake up and they feel great, and this way they can reassess what and how well they slept so that they can get another great night of sleep. Worth every penny..Version: 5.28
Better sleep how many stars do that?I read a few reviews and from what I gathered there were bad reviews they were rebutting. I stopped reading. I'm not going to waste my time reading negatives about a great program. Frankly I don't care what it does for anyone else as long as there are enough happy users to keep them in business. I wake up refreshed no matter how little or how much time I have to sleep. I can't explain how the system works, but it does. Not once in awhile, but every time. Don't be fooled by buffoons who have another mission. Good sleep combined with nutrition and exercise is more valuable than the vast majority seems to realize. Earl Brown.Version: 5.28
Latest Bug Fix is BuggyIn the latest update, you re-introduced the issue I have had where I pick up my phone in the morning, my iPhone 6 Plus screen is black and unresponsive. It seems that the screen and it’s touch features are the only thing that is turned off, as I can still say “hey Siri“ and she responds. Also, a knew bug introduced is that the Insights icon in the lower left corner will only close the app off the screen, and I can never get to the insights page with this update. When I double tap my home button, the app is still running and I can bring it back up. All the other icons are functioning normally. Yes, I know I have a “older“ phone, but I really do not want to give Apple $1,000 at this time in my life..Version: 5.150
Love it on my iPhone, but would love an Apple Watch appI have been using this app for a couple years now and it's great. I would say my quality of sleep has improved and I can tell how my nights of sleep affect my waking hours and productivity. Now I have an Apple Watch that would be perfect for this app but there's no companion for it. I don't mind continuing to use the app on my phone but I feel the company is missing out on other aspects that can be monitored like heart rate and more accurate movement tracking. Please develop an Apple Watch companion!.Version: 5.28
Wake up refreshed and on time, every time.I have always struggled with waking up. I have often had two or three alarms in my room to insure I get up on time. I can sleep through a radio or a buzzer going full blast for the full hour that the alarm is sounding and actually will incorporate that sound into my dreaming. With this app, it knows when I am close to waking up and it gently nudges me to wake up fully. I would have never believed it, but it works..Version: 5.28
Great app with a bug …I’ve been using this app for several years. It’s great. When my phone is face down and the app is tracking my sleep, the screen turns off like it’s supposed to. But if I’m listening to music and increase the volume or skip the track, the screen turns on and won’t turn off again until I pick up the phone and put it back down. I’ve had many nights when this has run the battery all the way down. Please fix if possible. Thanks!.Version: 5.168
Can't turn off alarmI've been using this app for years as my alarm and to help gauge the quality of sleep I get. A new "feature" has occurred. After doing a "snooze", If I happen to double tap the home key to go check my calendar before resting a bit longer until the next snooze, if you double tap to go back, the alarm tab is a blank white screen. When the alarm goes off there are no buttons to press. The only way to turn the alarm off is to close the app and lose that night's data. Pretty lame to have an alarm clock that you can't turn off..Version: 5.146
Money Hungry UpdateI’m sorry but updating this app really screwed me over. I paid for this bs. And now you’re wanting me to pay monthly to use the basic features I had since I paid for this app? You can’t use most of the features you use to now so you basically just scammed me. This isn’t what I paid for and I will be looking into getting refunded cause this was wrongfully done by a money hungry company😤..Version: 5.168
Used to love itI’ve had the free version of this app for about 2 years, and I used to really love it but recently it’s not been tracking my sleep correctly. I started getting insomnia 3 months ago and it hardly ever recognizes the 3-5 times I wake up. I’ll even actually get out bed or play on my phone and it’ll tell me I didn’t wake up at all. Nothing’s changed in how I’ve been using it so I’m not really sure why it’s not analyzing all of this. I keep it somewhat near me on my bed like it says to. I do love the alarm in the morning though, it’s made waking up less stressful..Version: 5.144
Paid for AdsI paid for this App a long time ago and a while back started getting ads for the premium service... after I already paid to get rid of ads. Well, I’m annoyed with the push for premium almost every night I launch the app. I paid already, for the 4 pack I believe... why update and require more money? Besides paying to get rid of ads, but still getting ads, the app works as expected and interestingly accurate. I know when I wake up in the middle of the night, it actually has the time recorded..Version: 5.168
Getting health conscious!I wasn’t really into “healthy lifestyle” until there was a company program that we actually get paid staying fit. And part of that “staying fit” are ways to improve sleep and being productive and staying healthy. This was app is the accredited app for our program. At first I don’t get it but eventually the program started changing how I view “building a healthy lifestyle”..Version: 5.168
Love this App!I’ve been using this for at least a year now. A very reliable alarm and I feel it’s pretty accurate recording the quality of my sleep. I did try to use a song from my library as the alarm once and I could not hear it when it went off...thus, I was late to work. So I just use the alarm sounds they provide and I’ve never had a problem. Great app!.Version: 5.148
Not a morning personI am NOT a morning person. I have been using this app about two months. The first morning that I was gently woken up by the subtle sounds, I hopped out of bed, made my coffee and was kind to others (not normal for me!) it has been a continuous happy journey. This app has changed my morning life and I am so grateful. I feel more rested and aware of the things that affect my sleep..Version: 5.28
Helpful and informativeI use this app every night in addition to my Fitbit sleep log. The two sets of data consistently match up, so I'm assuming it is fairly accurate. The app has locked up on me once so I always set my regular alarm to go off at a slightly later time for back up. With the app running overnight your automatic iOS updates will not install..Version: 5.28
Sleep dream!The Sleep Time app has been so worth the little bit of money I paid for it. I am a poor sleeper and I can tell from the analysis how frequently I am disturbed by children or dogs or life. I would do better to get eight hours of sleep a night, but, I'm so busy. I like the gentle wake-up best. So much better than a traditional alarm on the nightstand..Version: 5.28
Features Slowly Locked Behind Pay WallI got this app years ago and have greatly enjoyed its tracking features and alarm style. However, overtime more and more of the original features of the app are locked behind a paid subscription service. I paid for this app to begin with so the original features of it should be locked behind a pay wall. Soon you’ll just have to out right have a subscription to use the app even..Version: 5.168
I do like Sleep Time a lot, butThe visual is great, and I really like the sleep and wake cycle. What I don't like is the advertising and constant trying to get me to sign up for something when I enjoyed it so much for all these years. I'm willing to pay a little bit for the privilege but just cut the crap on the site. The old simple easy sleep site graphic and interaction was much simpler and more helpful. If you'll let me have that old one back I'll happily pay you!.Version: 5.28
Useful and seems accurate*** edited to 3 stars, down from 5. I paid for the app a year ago and it has now gone to subscription. I still use it, but I am dissatisfied with the current user interface and lowered access to my stats. It has a couple good white noise tracks and does what it says when I comes to the alarm system. When I pay for an app, I do not want it to go to subscription to get what I thought I paid for..Version: 5.28
Sleep LabI am addicted to this app. Wish it displayed current temperature but otherwise, works well. Like most others, can't really verify the data, but it seems reasonable enough, plus, never jolted out of bed. I always feel like I wake up more naturally. I feel like I can get a better estimate of how much I sleep every night..Version: 5.28
AwesomeBeen using this app for years at this point and it’s great and honestly if “math” is too hard for you maybe you need more than an alarm. Try the lite version which I did use before finally upgrading months later. I even switched phones and it saved all my data pretty sick alarm app..Version: 5.28
Great Sleep App!! But...Does tell me how I have slept and the alarm sound choices are better than they were. But...has some bugs. Often it won't let me turn it off with the hold bar at bottom for two seconds. Also it affects the controls of other apps while it is running..Version: 5.28
Long timeI started using this app in April of 2014 and have used it almost every weeknight since then. I love the way it wakes me up. I wish I had a way to export all of the data over to my health app though. It only goes back so far..Version: 5.416
Been waking up to sleep time for yearsI love this product. Easy to use. Intuitive. The window of when it can wake you up when you’re sleeping the lightest before the alarm time is great to keep you waking up and ready to go!.Version: 5.146
Ch-ch-changingI’ve been using this app for years. I loved the variety of sound that helped me fall asleep, and the gentle alarm that woke me up in the morning. I loved flipping my phone over on my bed for a few minutes of snoozing. However, more and more features are becoming “premium” or paid features. Soundscapes that I’ve used for years will now cost me a premium cost? Buh bye, Sleep Time. I’ll miss you..Version: 5.164
Good potential, some issuesThe soundscape doesn't work consistently and trying to shut it off often launches the in-app purchase screen. It can be a battery hog and crashes about once a week. I like the wake up and record keeping but it would be nice if you could see how much longer you have to sleep as well as what time you'll wake up..Version: 5.28
Nice app, but...I really loved this app and was happy to download it again when I got my new iPhone, but I was really disappointed to learn that they changed it to only people who were paying a membership fee could listen to their own music to wake up. I got the paid version of the app when I had my iPod touch specifically so I could wake up to my own music..Version: 5.28
Best app yetI love this app I have a lot of sleep problems and have to take a lot of medication at night and this app is handy for tracking my sleep. I let my dr review it every month to see how I'm doing. He is even impressed with this app and the heart rate app..Version: 5.28
Pretty GreatThis is one of the best alarm clocks I've used on my phone. I love how it shows the type of sleep received throughout the night. There have been a few times that it freezes and doesn’t record my sleep. I wish it would provide tips for sleep improvement..Version: 5.146
Great until the deafening ads pop upI have been using Sleep Time+ and Azumio's suite of fitness trackers for years, but when a loud advertisement jolted my partner awake last night while I was setting the alarm, I have decided to delete the app and switch to another tracker / smart alarm app. (Subscribing with a recurring payment just to remove the ads is not worth it.).Version: 5.28
Amazing sleep appI feel 10x more refreshed waking up with this alarm instead of abruptly with another.. I can see how well I've been sleeping at night and what times I hit the REM cycle. I seriously recommend purchasing this app..Version: 5.28
Needs fixedWorked well but now most nights I set the sleep and when I wake up and go to end the sleep tracking it will be off. I use this to track healthy habits for work and since this happens so frequently I am missing out on points which lead to money that I get to use toward my insurance premiums..Version: 5.160
Great AppI have been using this for quite some time. It always reliable. I have never had any issues with this app. I will continue using it and I recommend to everyone..Version: 5.28
