I have lost 12 pounds just by following its "red bar of shame" that appears when you need to move.

I walked nearly 6 million steps in a year with my Jawbone Up, and my fitness was improved so much that I lost 50 pounds and my resting heart rate is down to 52.

The only problem is the app for my phone, I have been using it for about 2 months, and I have lost 10 pounds, but the app has to be removed and re-installed every so often.

However, o returned it because the person I bought it for didn't like it because she thinks a fitbit will somehow be better

Works great easy o use
