SmartGlass is a multi-platform companion application for the Xbox 360.
Developed by Microsoft, and shown off at E3 2012, the SmartGlass app is available for Windows 8, Windows Phone 8, Windows Phone 7, Android and will soon be available for iOS devices (October 2012).
The SmartGlass app lets your phone work with your Xbox 360 console to bring rich, interactive experiences and unique content about what you’re watching or playing, right to the device that’s already in your hand. It provides options to interact with TV shows, movies, music, sports, and games.
Your Xbox friends are also available through the companion app.
