I don't understand the down voting. I guess it is shooting the messenger for his recommendation to use "shitty micro payments". But what is the problem with this recommendation? It is just the truth, anything else doesn't work, apart of some statistical irrelevant corner cases.
I didn't downvote, but it might have been the mention of using Enterprise Distribution to get around "what Apple & Google allows". Enterprise distribution isn't meant to be used that way and has the potential to get your developer account closed & blacklisted by Apple if they find out. Even worse, Apple may revoke your developer certificate so that even the software installed on user devices stops working:
I don't use it to get around anything, we have in-house iphone and ipad apps that Apple would never allow in the store because they are used to collect leads at our various physical properties. We are well within our terms of our Enterprise account.
