    Does it measure your heart rate? I'm curious to know how it knows you're sleeping!

    The sleep feature is actually pretty handy. Since it measures movement on more than one axis, you can solve those mysteries of why you feel like crap the next day. It requires wearing it on the wrist you use less, and I feel it's pretty accurate. Usually on days when I feel terrible, the FitBit says I woke up 6 times or more the night before.
