Microsoft principal program manager Rosa Thomas has announced in a presentation at Build that the Xbox SmartGlass app has been downloaded 17 million times since it was released in October 2012. Smartglass is currently available for Windows Phone, Android and iOS.
Rosa added that 89 percent of users returned to the app within a week of downloading it. Users spent on average 16 minutes per application when using SmartGlass.
Very few Xbox 360 games take advantage of SmartGlass, but more games on the Xbox One will have features dedicated to SmartGlass. The app is also able to control the console's music player and is able to be used as a keyboard.
