The free version is a 2-day demo app

Those in-app purchases over on the left of the iTunes page aren’t optional - the app gives you days 1 and 2 of a 12-week program; everything else requires payment to unlock. I’m used to apps like RunKeeper, where the free version is actually useful. I’ll try this for a couple days, but… I dunno.
