I am in no way averse to paying for an app or making in-app purchases, but the "details"on this app makes no reference to any "in-app-purchases" that may be required. So I download and open the app which gives access to two basic workouts and prominently features a "get the full version" button. Furthermore, there is no indication what the full version costs. Seems a bit "bait and switch" to me. Download at your own peril, I'll be deleting this on principle.
No doubt this is the best application i've ever seen!!! At the gym or at home this is a must have!
