A couple of things for people considering this app:
1) The moves/workouts are difficult and not customizable. If this is a problem for you start with a different app and consider working up to this one.
2) Its not child friendly. At all. Dont get it for your children. Its an app for adults who dont mind profanity.
3) You have to move the phone in between exercises, depending on where the moves are being done. You are given enough time to do this.
4) Reps arent counted perfectly. Thats because the app uses the technology it has available. i.e. The little camera on your phone. It is far from perfect technology.
If these things do not pose a problem to you, then this is a great, 5 star app! Its fun, its effective, it gets you up off your butt while engaging your imagination with a story that makes you feel like a hero! I am really enjoying it and plan to continue my superhero training for a long time!
