I just made a free iOS app (no in-apps) to follow how many push-ups your friends are doing. The app automatically create a monthly leaderboard powered by the number of push-ups made. It aimed to encourage improvement through competition.

My goal is not to promote it, it is simply to get your feedback about the app! The app is named PUWF - Push-ups With Friends and you can download it here: https://itunes.apple.com/us/app/puwf-push-ups-with-friends/id955478124?mt=8

I would really love to hear your feedback about that.

Thanks!
