With only 600 apps, the App Center is a brief listing of apps that utilize Facebook’s infrastructure in some way. Facebook will offer personalized recommendations, presumably based on its social knowledge of each user. App Center will be featured prominently in the mobile on iOS and Android, Facebook’s full dekstop site, and on Facebook’s mobile site.
Facebook is adding a top-level “App Center” link to the lefthand sidebar of every desktop Facebook page. Once there, users can browse for apps in categories or search and after finding an app, they will get the standard screenshots and descriptions. From the desktop, one can click a “Send to mobile” button to get a link for installation as well.
