I usually look at apps to see if they say in app purchases so I can decide if I want to download. I was under the impression this was fully functioning but this app only gets you to 20 push-ups. If you want more functionality you have to buy the Pro version. Just be up front with the fact that you are looking for payment and dont hide it behind a limited free app. I hate that. If they had been more straightforward I might have purchased it, now I am just going to delete it.
