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 love my Move. I never have to worry about it falling off like I did with my old Fitbit. It syncs wonderfully with my calorie tracker app and the daily "Today I will..." challenges have helped me make positive changes in my daily habits. The sleep tracker is a nice feature too. I love it so much, a coworker and her partner each got one based on my recommendation and they both love it too!
