The Sleep Cycle alarm clock is a bio-alarm clock that analyzes your sleep patterns and wakes you when you are in the lightest sleep phase.

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.

Sleep Cycle has become a huge success with a #1 paid app position in many countries, including Germany, Japan and Russia.

"It just works. Period. It does exactly what it advertises which is absolutely amazing."
- 5/5 star review at 148apps.com

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.
