although i did not like it for iPhone and i did order it for that purpose
but it's not because of the Gaming Controller, it's from Apple side (their high standards leads to less compatibility) it works with some games on iPhone5 "not all games" also it does not work on iPhone main screen.
i tried it on Note2 it's more practical as it works on the main window and it has more than mode for android.
it seems much more fun with androind devices.
in conclusion, this controller is one of a kind but for Apple it's not that much of a use.
