Jawbone UP MOVE Activity Tracker: Track the number of steps you take throughout the day, your caloric intake, and even sleep habits. Along with providing information, your tracker — which can be clipped onto clothing or placed in a pocket — will relay suggestions via the free app on how to improve your health.
I had an UP24 for about a year before switching to the Move. What I love most is how compact it is--I wear it clipped to the middle of my bra and you cannot see it. Plus I can continue to use the Jawbone software, and the Move has fewer connecting issues than the UP24 does. There is no "soft reset" needed, ever, which is great. I won't go back to a wrist-worn tracker.
