You can slide backwards ### 5/5 — love *2023-01-10, version 2.0* ive recommend so many people this app and it works so well for me! i love the layout and backgrounds, but i wish there could be an option to change the time it takes to go to sleep, since some people take shorter or longer. ### 5/5 — 非常喜欢，非常好用🙏❤️ *2022-10-11, version 2.0* 对生活帮助很大，而且非常简单易用 ### 5/5 — Taller aspect ratio? *2022-06-27, version 2.0* This app is fantastic and I really appreciate the lack of ads and micro transactions. I do wish that I could donate something to help update the app for the latest iPhones and their taller screens though. ### 5/5 — Works for me *2021-12-31* I now wake up and get going with relative ease. I’m not dragging, groggy, or grumpy. (I even love the colors and images used in the app.) The only change I’d love to see… The ability to set an alarm by tapping one of the recommended wake up times. Thank you for this beautiful tool. ### 5/5 — Its great *2021-08-02, version 2.0* I’ve been using this app for a couple months now and it’s really helped me. It helps a good estimate so I can be ready for the next morning there is nothing I have to complain about this app. ### 5/5 — Cool, simple, but needs to be updated! *2021-07-27, version 2.0* I love this app - I’m being picky, but would enjoy if it could be updated to take up the entire screen on newer iPhones. ### 4/5 — Please make into a widget *2021-03-13, version 2.0* Like, great app it’s literally gaven me better sleep. But, if there was a widget that allowed me to see the times that I would need to go to sleep in if I went to sleep now, it would make my life just that extra bit more ### 5/5 — This app has changed my life *2020-09-30, version 2.0* I have been using this for about four years. It’s one of the simplest apps/interfaces that I use, but it’s changed my life more than maybe any other program—When I use it I really don’t feel groggy anymore!! ### 5/5 — First night *2020-08-03, version 2.0* Trying this app for the first time after seeing the web app (sleepyti.me)featured in a 5 am routine YouTube video. I’m pretty pumped to see how this works out! I believe the creator mentioned how he thought of this idea and I agree with them! I also wondered why I would be tired even when I got more sleep. If this app or website works then I will be beyond thankful! Loving all the positive reviews! ### 3/5 — Allow it to make an alarm based on the sleep time *2020-05-24, version 2.0* Why would you not incorporate an alarm function??????? ### 5/5 — Please update it! *2020-04-02, version 2.0* I love this app, the calculator is not working correctly :( ### 4/5 — 7 days per week, 365 *2020-01-27, version 2.0* I’ve used this app daily for several years now. Would love an updated UI, but it definitely gets the job done! ### 5/5 — I use it every single night *2019-11-25* It may seem like such a basic app but i literally use it every night without thinking and it takes the guessing out of when you should wake up or go to sleep. If you’re know about the 90 minute sleep cycles then I recommend this app! ### 5/5 — Purely awesome!!! *2019-10-16, version 2.0* This app helps me to wake up with more energy than ever. The user interface is super simple and easy to use!!! ### 5/5 — The app helps me catch ma Zzz's bruh *2019-09-03, version 2.0* I'm telling you guys this all is literally a LEGEND. Never lacked on me not once. Literally slept at 10:40 and woke up around 4:44/4:54 a.m this morning💪🏽. The EARLY bird surely gets the worm❗️ ### 5/5 — Amazing app! Please keep it free and Ad free *2019-08-28, version 2.0* Great app! Just hope it stays free and ad-free 👍🏽 ## Most critical reviews (10 lowest-rated) ### 1/5 — Stopped working *2020-06-07, version 2.0* The calculator for picking the rise/bed time doesn't work anymore, it just says 12:00 am for all cycles. I love this app, but fix this. It suddenly just stopped working ### 1/5 — Mystified *2019-12-03, version 2.0* I don’t get the point of this. No countdown timer, no alarm, just tells you what time to go to bed. Better suited as a webpage than an app. ### 1/5 — doesn’t work *2019-05-23, version 2.0* The option to calculate what time you should go to bed doesn’t work, just shows up as 12:00am no matter what time you choose ### 1/5 — last updated 4 years ago??? whatt *2019-05-22, version 2.0* why? ### 1/5 — Rubbish *2018-10-14, version 2.0* I’ve read the other reviews and the company haven’t solved a problem from 3 years ago that I’m still having. Would rate 0 if I could. ### 1/5 — Love the website version but the app isn't working *2016-11-30, version 2.0* No matter what time I put as the wake time, it shows 12am as the time I should fall asleep for every cycle. I use the desktop site all the time and the app is beautifully designed but this version is not working correctly. ### 1/5 — Null options *2014-11-13, version 1.2* When you set a rise time to determine when to go to bed, all of the results are 00:00. Deleting the app until this is fixed. ### 2/5 — Buggy! *2021-03-27, version 2.0* Pick a time still not working... ### 2/5 — It's not sleepyti.me *2016-03-01, version 2.0* Not as good as the original sleepyti.me (sleep cycle times don't match up) and pick a time doesn't work. It's worth paying $1 for the original I guess. ### 2/5 — Fix the 'pick a time' option!! *2015-06-10, version 2.0* I love this app and use it every night, but the most recent update has caused the 'Pick a Time' option to stop working. I enter the time I want to wake up, and instead of showing the right times to go to bed it only displays "12:00 AM" for all the options. Please fix this!!! One of the best and most useful apps out there. ## Most praised reviews (10 highest-rated) ### 5/5 — Literally the best app ever *2026-07-21, version 2.0* You have saved my life so many times I love you dev. This app is perfect in every single way. A gift to humanity. ### 5/5 — Very good! Especially if you have trouble getting up in the morning. *2025-05-19, version 2.0* I don’t sleep enough hours all the time and half my struggle is just waking up and not feeling awful and unrested. This app really helps me wake up within a good time frame where I at least don’t feel like a brain fogged zombie. ### 5/5 — widget feature *2024-12-15, version 2.0* I love that this app is ad-free. I think it would be even BETTER if it could become a widget ### 5/5 — perfect *2024-07-29, version 2.0* this app is just perfect. no ads. no paywall. just a simple app, providing a simple purpose, but creating such a positive impact. I just love it. not too many like this one these days ### 5/5 — I love this app so much *2024-06-21, version 2.0* I just wanted to leave a review bc y’all are underrated. No ads or paywalls and I use this app once a day everyday usually and it’s a life saver. I have an absolutely unhinged sleeping schedule and with this app it lets me know the optimal times i should be sleeping. Like for example if i’ve been up all night but i need to get up tmr at 7, i might wake up feeling more refreshed if i wake up at like 6:47 opposed to 7 as you might think. Or on the other hand it’s easy for setting a bed time, and even if i know i can’t get my full 6 sleep cycles i know the next best time. And the pick a time feature lets you chose rise time and bed time. It’s just so simple and i’ve been using this for like atleast a year i wanna say. probably longer. I just want the devolved of this app to know your a godsend . It’s simple and effective ### 5/5 — This simplifies setting my alarm. *2024-05-19, version 2.0* I have insomnia. Before bed every night, i would calculate how many sleep cycles I could complete before waking up for work. Too much math, honestly. The U.I is simple but I appreciate its functionality. I use it every night, this is an amazing app ### 5/5 — Really useful *2024-01-31, version 2.0* Help me to manage my sleep and wake up rested. ### 5/5 — This app has been a life saver. *2024-01-23, version 2.0* This app has been such an incredible resource to my partner and me for many years. We are both neurodivergent and struggle with getting enough sleep as well as managing our bedtimes. Sleepytime helps us know when to lie down for bed so that we experience full sleep cycles and don't set our alarms to wake us up in the middle of a sleep cycle, potentially during deep sleep. Waking from a deep sleep will cause grogginess and that can negatively impact someone's entire day! This app has helped mitigate a lot of the problems we had for years with waking up- the foggy heads, super groggy feelings, etc. ### 5/5 — Does the job very well *2023-08-29, version 2.0* It helped me wake up feeling fulfilled and energized after studying until 2 am when I had school at 5:30. I don’t know how it managed to do this, but it did. So I had to drop a positive review to this app to let other people know as well for sure. ### 5/5 — Ol’e reliable *2023-07-23, version 2.0* Always works. Simple and pleasing UI. Nothing to complain about. 10/10. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
