Lark Silent Alarm and Sleep Sensor
Use your iPhone, iPad, or iPod Touch with the Lark app and the company's Bluetooth wristband to be awakened almost silently. A sensor in the wristband analyzes sleep patterns. The Lark system may be a good choice if you don't want to wake a spouse or if you have difficulty hearing an alarm.
