Misfit Flash. (Or the more expensive but nicer-looking Misfit Shine.)
Kind of off topic, but I was considering abandoning my Fitbit due to the lack of integration, then my puppy chewed it and destroyed it. I called the company and gave them my sob story. The person on the phone offered to send me a new one for free, even though it was my fault it got destroyed. Great customer service, and this made my decision to stick with Fitbit. It integrates well with MFP anyway, which is way less buggy then the Heath app integration so far.
Did I read somewhere that the Pebble Smart Watch now supports their app? If so does anyone have any experience with it? Will it track my steps in the background?
