Facebook just announced the App Center, a place for discovering and installing social apps/games that tie into Facebook’s developer platform. Apps offered in the App Center will be available on the web and mobile, including Android and iOS devices.
If you think Facebook is trying to take on Apple and Google’s storefronts directly, fret not. The App Center will be part of the official Facebook application and send mobile users to their respective storefronts, whether it be Apple’s App Store or Google Play.
