Popular App Store tracking website AppShopper’s iOS app has been pulled from the App Store following a violation of the recently added rule that says developers shouldn’t duplicate App Store functionality.
The violated rule, which forbids developers from cloning App Store functionality, was added back in September. It says:
2.25 Apps that display Apps other than your own for purchase or promotion in a manner similar to or confusing with the App Store will be rejected
As of now, there are a number of similar tracking apps (AppZapp, Appsfire) live on the App Store, but they could be taken down as well if they don’t offer “significant alternate functionality,” as noted by The Next Web.
