Sport, friends, one goal. Proofit uses the power of the group to help you keep the pace, whether you want to lose weight, build muscle or just stay in shape. Create a circle with your friends and set a weekly activity goal together. Prove every workout with a photo, whatever your sport. The week only counts once everyone has hit the goal. Every completed week grows your circle’s streak. If someone drops out, everyone starts over from zero! Watch your friends’ stories, react, comment, and send a wizz to the ones lagging behind. Every week, the last one gets a forfeit: they buy the croissants, or whatever else the circle decides. Feeling lazy? Use an excuse to save the streak. Your circle will definitely roast you for it. Unlock badges together. Get started with your friends. Now go prove it! Terms of use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
