The Call of Duty Elite App for both iOS and Android got a big update this week to support Call of Duty: Black Ops 2. You can use the app to check your career stats and recent match performances, edit your classes, and search for and apply to Clans.
You can also use it to stream Call of Duty Elite TV, access multiplayer guides, and track challenges. The iOS app is universal and compatible with all iDevices running iOS 5.0 or greater; however, the App does not have iPhone 5 screen support at this time.
Download the App Here for iOS and Android.
