This is how workout apps should be. One time purchase, no recurring fees, and no annoying trainer in the background. I know some people enjoy a trainer but I just don't. This game is amazing, and with the new ability to make custom songs by just moving to the beat and it maps it all for you it is even cooler. Highly recommend this one. It would be a 5 but it does feel a tiny bit unpolished in some spots, but not enough to pass on it!
