About this app

The app calculates the best times for you to sleep and the best times for you to wake up! It is based on sleep cycles of 90 minutes and calculates backwards. Waking up during a sleep cycle can make you feel tired, but waking after a cycle can make you feel more refreshed!

The SET ALARM permission is needed for the app to open your alarm application if you wish to set an alarm with a given time.

Really neat app. It's incredibly simple, but it gives me the only information I need. I like that it accounts for the time it takes to fall asleep in addition to calculating sleep cycles and that you can customize this duration. Plus, it sets automatic timers if you click on a specific time. So convenient!

I've used this app for years on several devices. A LIFEsaver for an insomniac like me. Many sounds to pick from and it works flawlessly. It didn't force me to rate or even ask. No ads or intrusions at all, no weird permissions and no glitches. It's lightweight and you only download the sounds you like. Great app. Great job. ThanX!

best app ever. no ads, no forcing you to rate (I searched it up just so I can rate this) and very accurate. I also just realized that you can click on the time and it will automatically set an alarm. I've been using this for over a year now and I've only realized that now XD. I found out about this on tumblr and used the site online and at one point I decided to check if there was an offline app of this and sure enough there is. I love the simplicity. I absolutely love this. Highly recommended.
