Sleep Cycle Alarm Clock. iPhone & iPad. $.99. What if your alarm clock could read your sleep cycles and gently wake you when you were at your lightest sleep phase to make the process less jarring? That would be pretty space-age, wouldn’t it? Well, the future is now with Sleep Cycle Alarm Clock. The app uses the iPhone’s accelerometer to measure how much you move at any given phase. It will then wake you during a 30 minute time span ending in your set alarm time when you are at your lightest sleep phase. The app also analyzes your sleep over time and presents you with daily sleep data so you can monitor your own sleep patterns. While it isn’t effective for very heavy mattresses, like foam mattresses, as you need to place the phone under your mattress, users report that it performs quite well and accurately. If you suffer from alarm clock stupor, maybe it’s time to give Sleep Cycle Alarm Clock a try.
