It acts as a companion app for Xbox video game consoles, providing access to Xbox network community features, remote control, as well as second screen functionality (formerly branded as SmartGlass) with selected games, applications, and content.

Through the app, users can access their activity feed, Xbox Live friends and messages, manage their party, watch saved Game DVR clips, browse OneGuide, and view their achievements.

Microsoft demonstrated use cases for the new app within both games and entertainment, including a minimap for Ascend: New Gods, a second screen experience for School of Rock with supplemental content, and Game of Thrones (with interactive maps and family tree diagrams).

This follows a U.S. court ruling that prevents Google from requiring its Play Billing system, enhancing choice for developers.

Additionally, Microsoft is developing a browser-based Xbox mobile store, initially focusing on first-party games and later including deals and in-game items.
