Now why would you want to punch your friends? Seems counterproductive in maintaining friendships. Punch Your Friends is a fun app to clobber some of your friends and enemies. Even your boss. Another useless app making a splash for a week or two. It’s free. If I had to pay for this I think Phillip Kaplan would be punch worthy.
Take pictures of your friends and then “virtually” punch them by tapping the screen. Fun sounds and bruising effects. Email the final, altered photo to share it with your friends.
