【實用健康app】SleepyTimer Bedtime Calculator|最夯免費app-綠色工廠好玩App

Getting a good nights rest isn't always about quantity but quality. This app will help you by setting alarms for when you should head to sleep and wake up in order to wake up after REM sleep. A full REM cycle is typically 90 minutes of sleep and ideally we should sleep for about 5-6 rem cycles. SleepyTimer is a bedtime/sleep calculator, sleep alarm, or whatever you prefer to call it.
