Lark

From a Stanford grad who decided to get in bed with a handful of expert sleepers (Kevin Bacon?), Lark is a silent alarm clock outta Palo Alto that syncs any alarm-equipped Apple product (iPad, iPod Touch, iPhone, etc.) with a watch-like, pillow-soft wristband that tracks your sleeping patterns and gently wakes you using a built-in vibrator, and no, that's not the joke.
