An iPhone app for insomniacs - Sleep Cycle alarm clock

If you've ever woken up to a blaring alarm only to feel like you just went to bed five minutes ago, you're not alone. The problem, if Sleep Cycle alarm clock is to be believed, is that you're getting woken up at the wrong time in your sleep cycle, when you're in a deep, restful slumber. Sleep Cycle alarm clock uses your iPhone accelerometer to judge when you're ready to be woken up and as a result, you'll feel better rested. Jay Goldman explains.
