Trying to get the word out about this awesome iPad app for Halo 4. The app gives a breakdown of every game you've played (or anyone else you want to follow) and shows you every weapon kill you get along w/ your medals and basic K/D, assists, betrayals, etc, tap on any weapon or medal to get a full description and a bunch of other cool features. All for free and no need to login to an Xbox Live account!
The app actually gets the stats before you exit black screen on the Xbox! While you are in black screen (right after a game ends), pull to refresh the app :)
