Sleep Cycle Alarm Clock (iPhone) is an alarm clock that analyzes your sleep patterns and wakes you in the lightest sleep phase - a natural way to wake up where you feel rested and relaxed. As you sleep you go through different phases that range from deep sleep to light sleep. The phase you are in when your alarm clock goes off is a critical factor regarding how tired you will feel when you wake up. 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.
