Origin

Origin is the social network used for EA games, such as The Simpsons: Tapped Out. Currently, iOS and Android devices support Origin. Android users could use Origin from April 2013 onwards. When visiting friends using Origin, they would appear in Alphabetical order prior to the release of the Whacking Day 2013 Event in April 2013. This was partially due to the fact that players with a username beginning with 'y' or 'z' did not get visited often as they were always at the end of the list. In the Valentine's Day 2014 Event it reverted to alphabetical.

Wikipedia Description
Origin (formerly EA Store) is a digital distribution, digital rights management system from Electronic Arts that allows users to purchase games on the internet for PC and mobile platforms, and download them with the Origin client (formerly EA Download Manager, EA Downloader and EA Link). Origin for Mac has been available since February 8, 2013.

Origin features social features like profile management, networking with friends with chat and direct game joining along with an in-game overlay, streaming via TwitchTV and sharing of game library and community integration with networking sites like Facebook, Xbox Live, PlayStation Network, and Nintendo Network. Electronic Arts has stated that it wanted Origin to match Valve's Steam service, Origin's leading competitor, by the end of March 2012, by adding cloud game saves, auto-patching, achievements and rewards, and cross-platform releases.
