Sleep Cycle Calculator (Pro)
The ad-free paid edition of the sleep phase calculator, using your phone's native alarm.
About Sleep Cycle Calculator (Pro)
Sleep Cycle Calculator (Pro) is the paid, completely ad-free edition of the sleep phase calculator. It works out when to go to bed if you need to be up at a specific time, or when to wake if you are going to sleep now.
It deliberately uses your Android device's built-in alarm rather than running its own timer, so it does not sit in the background draining battery.
