Sleep Cycle is a bio-alarm clock and sleep tracker which uses your iPhone's accelerometer to monitor your movements through the night and wake you when its alarm will be least disruptive to your natural sleep cycle.
A bio-alarm is like the opposite of a snooze button. So instead of the scattershot approach of setting your traditional alarm for 6AM and hitting snooze until you absolutely must get out of bed at 6:30, you'll set Sleep Cycle for 6:30AM and count on your iPhone to decide when during the preceding thirty minutes you are already most alert and close to wakefulness anyway. As a result, you only have to wake once (per day, sorry) at a closer-to-ideal time, helping you to start the morning feeling more refreshed and less groggy.
If an ounce of prevention is worth a pound of cure, and an iPhone is nearly five ounces, then how many trips to the doctor can you avoid with new wellness tracking apps Body & Mind Connection for iPhone [App Store, $0.99] and iPad [App Store, $0.99] and Optimism [App Store, Free*]?
In both apps, you spend a short amount of time each day assigning number ratings to mood, amount of sleep and exercise, how healthily you ate, etc. The apps then help you establish relationships between lifestyle factors and various areas of well being, and ultimately help you reach your goals with their fancy progress-tracking charts.
