Waking up easy is all about timing. Sleep Cycle alarm clock tracks your sleep patterns and wakes you up during light sleep. Waking up during light sleep feels like waking up naturally rested without an alarm clock.
While you sleep, you go through a cycle of sleep phases. The first phase is light sleep, followed by deep sleep. A full sleep cycle lasts about 90 minutes and is normally repeated several times each night.

Your movements vary with each sleep phase. Sleep Cycle uses sound analysis to identify sleep phases by tracking movements in bed. Sleep Cycle then wakes you up during your lightest sleep phase, using a predefined 30-minute alarm window.
