Three companies successfully combined their creative talents to produce a unique sleep timer application for the iPhone. Power ZZZ 1.0.1 lets you get that much-needed power nap in on your schedule. It features a built-in sensor that recognizes when you have fallen asleep and allows you to sleep the exact amount of time you wish. Fall asleep to soothing sounds and wake-up to upbeat tunes or if you wish, use the conventional alarm. The app has 18 ambient Sound/Music selections to choose from.
