This aap does the job. ### 4/5 — Planning sleep *2018-10-11* Straight forward uncomplicated app which helps me plan my sleep so that I wake refreshed. Has he worked well for me. ### 4/5 — good but should have a reminder for wake up *2018-05-18, version 2.0.1* pleaseeeee ### 4/5 — Has been updated for IOS11 *2018-03-06, version 2.0.1* Functionality is there now, although the splash screens display for nearly 5 seconds every time the app is opened. ### 5/5 — Fairly simple app. *2017-08-14, version 1.1* Works well and very informative. ### 5/5 — Great *2016-04-05* It helps me know when to settle down into bed, especially if I have and activity of some sort in the morning. ### 5/5 — Perfect *2014-12-22, version 1.1* Very simple ### 5/5 — Nice, simple, with reminders *2014-11-16, version 1.1* I like this app. It is very simple and easy to use. It will add a reminder to tell you when to go to bed. I like the color scheme a lot. It also includes the date when selecting a time which can be very helpful. There are no customization options for time to fall asleep or number of cycles to display, although I don't think they are needed. It uses 15 min as the time needed to fall asleep which results in nice round numbers in 15 min intervals. It shows 6 cycles that are colored very nicely with 5 to 6 cycles both being green, although it doesn't list the number of cycles next to the times and doesn't list the total sleep time. The input dial hasn't been updated for the new iOS but still looks good with the rest of the app design. Overall I really like this app the best out of all the other similar types of sleep calculators. ### 5/5 — hi *2014-07-03, version 1.1* I'm just being nice so you will have a 5 star app ### 4/5 — Great app *2013-08-24, version 1.1* Great app, I've been using this every night for a long time to figure out when I should wake up. Love the new design, but I miss the sleep tips, I was hoping that with the new design there would be more sleep tips. Also I'm not sure if the new design does this as well but I like how to previous design highlights the most optimal times to wake up. Looking forward to updates ! ### 5/5 — Great app! *2013-08-23, version 1.0.1* Helpful for getting a good night's sleep! ## Most critical reviews (10 lowest-rated) ### 1/5 — It’ll save information from your phone *2022-07-12, version 2.0.1* When you enter the app and you have copied text in your clipboard, this app saves that information without asking. Messed up ### 1/5 — Can’t set my wake up time *2020-08-30, version 2.0.1* unfortunately I can’t get this app to set my wake up time so I can figure out the best time to go to bed. I have tried and tried and have just concluded that my energy and time should go to getting another app that actually works. ### 1/5 — Not working out *2020-04-02, version 2.0.1* Unfortunately, it doesn’t work.😩 Every time I try to use the when to go to bed function and try to edit the time it doesn’t update and the banner stays up and won’t go away. If it does update the time it stays up and Can’t see the rest of the go to bed by a certain times ### 1/5 — Overpriced *2019-11-26, version 2.0.1* Subscribe What? Everything’s subscription these days. 40 bucks for a year??? Go subscribe a friend for a year plan, man. Miss the good old days when apps were $0.9~9.9 ### 1/5 — Not what I was expecting but it’s ok *2018-01-08, version 2.0.1* It’s a very nice app very simple too but it’s not what I was expecting I was expecting something that would tell me if I go to bed at a time then I will wake up at this certain time. ### 1/5 — Needs bugs sorted. *2017-11-04* The if I go to bed now option doesn't automatically refresh unless you restart phone:( ### 1/5 — Excellent app, but needs to be updated for iOS 11 *2017-09-21, version 1.1* I love this app but I just updated to iOS 11 now I cannot use it. ### 1/5 — Average so far *2013-05-12, version 1.0.1* App crashes once opened. ### 2/5 — Glitchy :( *2017-11-05, version 2.0.0* I've been using this app quite a bit for about a year to get an idea of when I should go to bed to get a good amount of sleep. The new update is certainly a step in the right direction as it had been quite a while since since any form of update had hit this app. However, new strides often don't come without their faults. The issue I have this nee update is it can be glitchy when inputting a time to wake to get the suggested wake up times. I will enter 9:00 AM and tap out of the selection box to have the list update. Instead, it will set whatever time I put behind by one hour, in this case it will say 8:00 AM, which is incredibly frustrating. **Developer response:** Thanks for pointing that out! Sorry about that. Should be fixed in the new version, check it out! ### 2/5 — Update please *2017-10-12, version 1.1* Love this app and used to use it every night. However, since I updated my phone the app won’t open so I can’t use it. ## Most praised reviews (10 highest-rated) ### 5/5 — I use this every night for years *2026-03-27, version 2.0.1* Shows different times based on sleep cycles.
