Description

Want to wake up refreshed? Every time you sleep, you enter into a series of REM sleep cycles that last for around 90 minutes, and waking up during one of the cycles will make you feel groggy and exhausted.

SleepyTime is an app designed to help you wake up in-between sleep cycles and allows you to start the day with a clear mind.
