The rankings and awards are fun, but thats really the only positive thing I can say about it. There are much better fitness apps out there.
As for rewards, they arent passively earned with your acheivements. You earn points, and then you have to claim each individual award, a process that can take several minutes after your workout. The prizes take so many points and the claiming takes so much time that it probably the least productive use of your time when it comes to money saving... you could get more return for your time by washing and reusing sandwich bags.
