The FitBit Ultra is a unique wireless gadget that clips on your belt and keeps you on track for your fitness goals. The device syncs wirelessly with your laptop everyday and tracks the number of steps taken, miles walked, stairs climbed and calories burned.
Another cool feature is that it tracks your sleep. How many hours you slept, how many times you wanke up...etc. Take a look at Eric Chilton's review.
The FitBit Ultra runs about $100.
