Wakemate

WakeMate makes personalized alarm clocks that sync with both a user's body and their cell phone, enabling the iPhone alarm system to sound at the end of a REM cycle. The application/ wristband system also provides a full sleep analysis on their Analytics Platform. The WakeMate uses a science called actigraphy to analyze your sleep. Actigraphy uses an actigraph (the WakeMate unit) placed on a subject's wrist to monitor the motion. The motion data is then analyzed to determine sleep patterns and circadian rhythms of the subject. WakeMate was funded by the startup incubator Y Combinator.
