Sleep Cycle Alarm Clock
Sleep Cycle Alarm Clock is like the Rolls Royce of sleeping apps. Place your phone under your sheet at night before you go to bed, and Sleep Cycle will track your sleeping patterns and display them to you in a graph the next morning. In addition to tracking the time you spend asleep and awake during the night, Sleep Cycle will wake you in the morning at the time that you're in the lightest sleep, assuring that you wake up feeling more refreshed than ever.
