Facebook has launched what it calls the App Center, a "new place for people to find social apps." Obviously similar to mobile stores like Apple's App Store or Google's Play store, the App Center will aggregate canvas, mobile, and web apps on Facebook.
The social network says that, in the "coming weeks," people will be able to access the App Center on the web and in the iOS and Android Facebook apps.
Facebook hopes that the App Center will become the "central place to find great apps." They're currently encouraging all developers to create an app detail page, which is required for being listed in the App Center, and will become the new destination when non-users search for your app on Facebook.
