> Could you do it with a licence-type scheme, similar the one the OS use with their new maps? Each map has a unique code revealed under a scratch panel, which is then used to allow access to the relevant download. Then it wouldn't matter what your selling system is.
As far as I can tell, this is a different system to the OS App which appears to be a subscription sevrice. A map download is different to an App with the extra functionality that an App offers.
Our understanding is that it isn't possible to have 'vouchers' or 'codes' for in-App purchases under the terms of the Apple App Store. We wanted to use the in-App purchase system to make the App more flexible for people when on the move so that they could buy crags without having to enter their card details all the time. Other Apps do use an ex-App system but with these you would need separate log-ins and have to enter your card details each time you bought a package. If you have Amazon Prime then you need to log into Amazon in order to buy a movie for example.
Also, scratch panels in each book are surprisingly expensive things to include which would almost certainly mean we had to put the price of the books up.
We are looking at options for improving our options for selling App packages since the Apple system is very restrictive but, as I said above, we do regard these as different products which are used in different ways and we currently have no plans to allow unrestricted free App access for book owners. The only exception might be if we can find a method of doing it for direct sales from the web site and then it would be likely be for special offers for limited periods only.
