I recently bought a fitbit, their online dashboard is pretty similar and you get access without a monthly fee. I'm pretty sure you can sign up and try it without getting a fitbit tracker, but the tracker is pretty nifty and it lights up the dashboard with all your info.

I have an aria, not a fitbit, and it's pretty cool. I really really really want integration with mint.com though, then you'd be able to track the fitness goals vs money spent, and come up with an optimized plan for everything.

I've been using mine for two months and I love it. They have an data API http://dev.fitbit.com/ and said they may open a hardware one too.

I got a flex a month ago and I love it! I don't use the silent alarm feature, because I'm a light sleeper and I wake up when I wake up. The food log is a feature that I thought I won't use, but I am. Wish I also had a heart monitor.

Does the vibrate wake up feature work well? Do you feel you are able to wake easier? That is pretty much the only feature I care about.
