Good overall. Needs a few tweaks.

#1. Fitbit needs to make the ability to undo a friend request. Its too easy to accidentally request others, I was trying to scroll through the list and I bumped it and it sent a friend request I didnt intend to send, and there is no way to rescind it. Now I look creepy.
The rest of the app seems fairly polished. Good iPhone integration and feedback/motivation to keep moving.
