Hello guys, I looked but couldn't find an answer to the following question.. I have a product that is sold on a independently on my website. I would like to allow Iphone users to enjoy my service abilities, and therefore, I need to have a small application installed on the users device. My question is: Do I have to charge solely through the Appstore? Or can I allow the app to be downloaded free and the credits can be purchased on my site, or through the appstore? I need to have the app installed, in order to make a better service, so working without an app is not an option. Thanks for anybody who helps!!
