Version 1.5 of the application (also available for iPod touch) brings play, pause, rewind and fast-forward controls, as well as access to the four coloured buttons.
The free update also adds the Quickplay mobile dashboard functionality seen in the Windows Phone version.
This allows users to start games or entertainment apps - iPlayer, YouTube etc - or discover new content directly from the handset.
iPad update, Android debut
Alongside the iOS enhancements comes the first iteration for Android phones. However, that app doesn't bring the Quickplay or remote control options.
The Xbox app team has had a busy time of it in recent weeks having launched the AirPlay-like SmartGlass application at E3 2012.
