Since you move differently in bed during the different phases, Sleep Cycle uses the accelerometer in your iPhone to monitor your movement to determine which sleep phase you are in. Waking up in the lightest sleep phase feels like waking without an alarm clock – it is a natural way to wake up where you feel rested and relaxed. See how it works

Good news: Sleep Cycle alarm clock for Android is here!
