We've built an app and are currently managing subscriptions via the website and with credit card.
Our business model requires the user to buy a base subscription then pay additional smaller subscription cost per user.
In exploring in-app purchases, I see that "In-App Purchase items cannot be shared across applications".
We currently have an iPad app that acts as a window to our existing web service and we're developing an iphone app with a different view into our service.
If someone uses in-app purchase to pay for a base subscription on the iPad, will we be in violation if we let their login work on the iphone app also?
Thanks.
