In reply to dereke12000:

I'll reply to this question, as it has been asked been asked by several people, and feel qualified to do so (I have developed and published several apps, both for myself and 3rd parties):
Apple does not allow any in-app purchases that are not routed via their app store. They used to allow it, but they changed the rules a few years ago. For an example of how this effects you as a user, just download the Kindle app for your iPhone/iPad: it will sync all your purchases, but if you want to buy a new book you are routed to the Amazon
web-page. You cannot directly buy in-app.
Apple does allow syncing of purchases made outside the app-store. You can buy a book at the Amazon web site (via your browser), and then associate a Kindle app (whether on ipad, android or whatever) with your amazon account, and it will download all your purchases.
In the Rockfax scenario, a putative setup might be that you would buy an e-guide at Rockfax.com, download the app for free then link your device to your rockfax account, which would then download the data that you have bought.
In fairness to Alan and Rockfax, there are good reasons why you might not want to do this:
- the stats for people buying IAP directly via the app-store are considerably higher than those for buying on an external web-store. Amazon get away with it because they are pretty much the reference for e-books, and already have a very established web store.
- technically it is marginally more difficult to do as it requires a slightly different mix of skills. (though given the technical ambition of the rest of the app, I don't see how this should be an issue).
Hope that helps
(Congrats BTW to the rockfax team for the app, I'll definitely be getting it once its out - and I look forward to being able to sync between my iPad and Galaxy S3 in the future!).
