The XBox Live app for iOS still doesn’t work on my devices. But, the Xbox Companion app for Windows Phone finally became available (after the iOS version) and does work.
And, it does a lot more than the iOS version. The Xbox app for iOS deals with messages, shows achievements and manages the avatar. The Windows Phone version requires that the Xbox be on at the same time and can be used as a adjunct limited controller. You can, for example, navigate around the Xbox and launch a game. Once in the game (Fusion:Origins in my case), the controller function did not work or did not have enough buttons (no “Start” for example) to be useful. It can also provide details about games, music, TV shows and movies playing on the Xbox.
