EA Battlelog is a lot like Call of Duty Elite, allowing you to view your progress through a mobile device.
EA Battlelog does default for the PC version, so looking at your console stats is a little awkward.
EA Battlelog is designed to be a social application, but it is missing a lot of functions. The app is great to look at your own information and you are able to look at other players' stats and give “Hooah!” to others, which is the equivalent of a “Like.”
The app is informational and serves as a hub for updates but you cannot directly affect your game on any platform. EA Battlelog would have been great when the game was first released but there has been so much time since the release and subsequent patches that it may not be as important for most players.
EA Battlelog is a good info app, but it does not do much else.
