Do you feel tired all the time and just can't figure out why or perhaps you've just always been curious at how well you sleep?  Well one of the many uses of the current fitness tracker devices is sleep tracking.  Don the device before heading to bed and it will give you information about how much you tossed and turned and if you ever woke up in the middle of the night.  Pretty interesting stuff.  In the past when I reviewed the Fitbit devices, this was the single most fascinating aspect of the wearables to me.  I guess I just always wondered what I was doing all those hours while I was off in never, never land.
