Billed as the "un-alarm clock," LARK is a sleep system in which you program wake-up times into your iPhone, iPod Touch, or iPad, slip on the wireless wrist band and then hit the sack. When it's time to rise, the band wakes you with gentle vibrations. The best part? If you and your partner are on different schedules, it rouses only the person who needs to get up, as there's no audible alarm.
