Upon opening the app Im faced with a "purchase" button at the bottom of each page. So am I purchasing the book or some head? Ha! This would have been 5 stars had you just put the price of the book upfront on the app, instead of trying to slide it on in there. #1 factor in any good sex: building trust. Your app fails to build trust with that sneaky purchase button....over $1.99? Why not just charge it upfront for the app?
