Online magazine store, Zinio, has pushed an update for its app on iOS today that adds the ability to purchase magazines using one’s iTunes account from within the app. Prior to the update Zinio users were redirected to a Zinio web page to log in and confirm the purchase. With this update, Zinio now falls in line with Apple’s subscription policy for books, magazines and newspapers publishers/retailers that makes it mandatory for them to enable in-app purchases if they offer a link to redirect users to their own sites for transactions. Recently Kindle, Kobo and WSJ updated their respective apps and removed links to their site rather than bowing to Apple’s policy. Zinio’s global executive vice president and chief marketing officer, Jeanniey Mullen, has confirmed to us that magazines bought using an iTunes account will be accessible on non-iOS devices provided one uses the same Zinio credentials on both the devices.
