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 cycles of sleep states. The first state in a sleep cycle is light sleep, followed by deep sleep and a dream state referred to as REM-sleep. A full sleep cycle lasts about 90 minutes and is normally repeated several times each night.
Sleep Cycle alarm clock
Your movements vary with each sleep phase. Sleep Cycle uses sound analysis to identify sleep states by tracking movements in bed. Sleep Cycle uses a wake up phase (30 minutes by default) that ends at your desired alarm time. During this phase Sleep Cycle will monitor signals from your body to wake you softly, when you are in the lightest possible sleep state.
