Microsoft promised that Xbox SmartGlass would be cross platform, and they have delivered faster than I think anyone suspected.
The Xbox SmartGlass app is now available for free for Android and seems to be getting pretty good reviews.
The description reads as below.
Use Xbox SmartGlass to enhance your entertainment on Xbox 360.
Xbox SmartGlass 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. Interact with your favorite TV shows, movies, music, sports, and games, and bring remote control to a whole new level.
You can also connect with your Xbox friends, track and compare your achievements, and change up your 3D avatar.
The app can be found in the Google Play store here.
