Regrettably, Azumio pays very little attention to this app and it hasn’t been updated in a while. [edit 06/02/26]: Azumio completely broke the tag functionality with the latest update. Let’s hope they get it fixed. There is no way to get the sleep data out of the app that I’ve found, even with the Premium version. Supposedly it syncs with the iOS health app but the Health app finds no Sleep Time data to sync so 🤷‍♂️. Also, it’s extremely buggy. Crashes a lot when trying to update tags, etc. I would move to a different sleep tracking app if I could get the data out of this one. ### 3/5 — Buggy but usable *2025-03-06, version 5.416* I’ve been using this app since 2012 so I have amassed lots of data over the years.

After many, many years of using this app, which I have to date found excellent, this loss of function is REALLY annoying. Please can it be fixed? ### 3/5 — No more heart rate function *2023-09-08, version 5.416* I used the heart rate function every morning. Following the last update it’s gone. Very disappointing. ### 4/5 — Good but needs updating *2023-01-31, version 5.168* It’s been years since anything has been done to this app. It’s generally solid but has a few bugs. Does a decent job of tracking your movements during the night. Has “insights” to review your sleep history. Has an alarm that will wake you when it’s best for your to wake based upon your sleep cycle. Bugs: -No method to edit tags -No way to filter tags without crashing the app -Sometimes the app can’t be taken out of the sleep tracking mode ### 4/5 — Great app with a bug … *2022-09-17, version 5.168* 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! ### 3/5 — Often hasn't record when I wake up *2022-01-04, version 5.168* I'm very good at turning off alarms, and sleeping through them... (this ap doesn't really go out of its way to wake me in a light sleep mode...) and when I eventually wake up, all the data is lost, and it's not on any more. Happens more than 50% of the time Just recently jumped from 100mg to 160... I have no space left Would not have updated if I'd realised. And that's not including my data. Over 200mg now... disappointing ### 3/5 — Needs up-date *2021-05-13, version 5.168* I like what the app can do. What it says is that is is good for sleep problems. I haven’t found an app that notices when the phone is still to note how long it was still and ask it it was charging, away from patron or was it a sleep attack (an unintentional nap caused by narcolepsy). The app description sub-title says something about naps - you can’t read the rest of the description. This app also hasn’t been up-dated in over two years. I’m not willing to buy a subscription when there’s no consistent checking for up dates. Also, when it says in app purchases, it needs to be clarified what the other charges get you, maybe $1.99 gets you Ad-free? $4.99 gets you what? I get that $9.99 is for the monthly subscription & the $29.99 is for the yearly subscription. But why are both of those amounts on their twice? I just need a little more help. The app is very good though. ### 1/5 — Needs work! *2020-08-22, version 5.168* I just bought the app 2 days ago so I could link it to my employers health tracker for health and wellness incentives. It worked the first night and no it won’t open at all. I click on the app the starting page pops up and then disappears. This is why I tend to stick to free apps with good reviews, thankfully I’m only out $1.99 bit very frustrating! ### 3/5 — ログイン後に利用できない *2020-08-06* いつも利用させていただき、睡眠の質が知れて重宝しております。 本日、端末を変えてからFacebookでログインをしました。 アプリを開いても、タイトル画面が一瞬表示されるだけで、アプリ自体が閉じてしまいます。 魅力的なアプリなだけあり、今後の活躍にも期待しております。 いち早くの改善をお待ちしております！ ### 3/5 — Paid for Ads *2020-08-06, version 5.168* I 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. ### 1/5 — Won’t open! *2020-05-27, version 5.168* I paid for this app and it won’t open. ### 1/5 — 돈 아깝네요 2500원 하루 쓰고 지웁니다 개 그지 같네쇼 *2020-04-03* 재곧네 ### 1/5 — Full Crap *2020-03-21, version 5.168* Inaccurate. Doesn’t even show full report. ## Most critical reviews (10 lowest-rated) ### 1/5 — Обычный будильник *2026-08-12* В своё время убрали измерение пульса ### 1/5 — Used to love it *2026-06-17, version 5.454* I used this app for the past 3+ years without issue, open the app and use. Now with the most recent update, it now requires an email. No thanks, so long. ### 1/5 — Akku Verbrauch *2024-08-19* Seit einer Weile zieht die App nachts sooo viel Akku, dass mein Handy Akku verliert anstatt sich aufzuladen. Batterie Einstellungen bestätigen dass es an dieser App liegt. ### 1/5 — Misleading Description *2023-03-30, version 5.168* One needs to pay to download the app to just get the alarm feature. Even the alarm feature is as basic as Apple Clock with no option to select the alarm sound. All the highlighted major features are hidden behind another subscription. Why do someone need to pay to download a basic alarm clock? ### 1/5 — Paid for the app, and it wanted me to pay an annaul subscription *2023-01-08, version 5.168* I paid to download this app, and as soon as I downloaded it, I was prompted to pay for premium for £25 a year to unlock most of the app. Useless app and I’m awaiting my refund. ### 1/5 — Kostet mehr als angezeigt *2022-01-05* Funktioniert nur mit Premium Update!! Dazu muss Mail Adresse angegeben werden! ### 1/5 — Awful app *2021-10-24, version 5.168* App is not worth (even $2) after switching to iPhone from android I have been very happy. But something like a simple alarm that will override the phone volume is an issue… #EpicFail ### 1/5 — App keeps crashing *2021-07-21, version 5.168* Crashing and not saving data from overnight. ### 1/5 — Don’t work with iPhone 11 *2021-01-07* it was the best, today they don’t update or support it, lamentable ### 1/5 — Unethical *2020-08-23, version 5.168* I paid already. ## Most praised reviews (10 highest-rated) ### 5/5 — This Sleep App *2025-04-04, version 5.416* Helps me to know how much sleep I’m actually getting. I do love the soundscapes to help me fall asleep. Makes it easier. ### 5/5 — Great sleep health app *2023-10-07, version 5.416* This app has helped improve my sleep more than any other sleep app ### 5/5 — Long time *2023-09-11, version 5.416* I 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. ### 5/5 — 환불 요청 *2021-02-21* 환불 요청 드립니다. ### 5/5 — Getting health conscious! *2020-04-26, version 5.168* 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”. ### 5/5 — App does not open! Needs iOS 13 update! *2019-10-26, version 5.168* It’s been a year since this app was updated. ### 5/5 — Great *2019-10-01, version 5.168* Excellent app! Works as advertised . ### 5/5 — 睡眠の意識向上に *2019-04-30* 生活の質を高めるにはまず睡眠から。その意識付けができるアプリだと思います。必要なのはアプリを起動する習慣つけですか😅 ### 5/5 — Money Hungry Update *2019-04-24, version 5.168* I’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😤. ### 5/5 — Nie wieder ohne *2019-03-18* Hat mir sehr geholfen mein snooze problem in den Griff zu kriegen. Nutze die App seit über 5 Jahren! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
