The company shared most of the details about how the store will work during a May press announcement, but to review: it’ll be one central store for finding any app across web, iOS, Android, mobile web, etc. (Credit: Facebook) 
 
 Facebook's App Center has arrived, and it's got more than 600 apps in tow, including big hitters like Pinterest, Draw Something, Nike+, Path, and Ghost Recon.  Facebook has launched an app store, similar to that for the Apple iPhone, in a bid to turn the social network into a key entertainment platform online. You’ll only see high quality apps in the App Center, based on user ratings and engagement. Each person will have a personalized experience in the App Center, with recommendations based on the apps they and their friends use, whether that be games or fashion, food, fitness, travel, or other lifestyle apps. If you'd like, you can also play it right then and there (if it's a Web app) or send an iTunes or Google Play link to your mobile device (for mobile apps). Case in point, I was able to send a Pinterest app link to my Android phone, when in fact, Pinterest is only available on iOS. If you can't find App Center yet (it is gradually rolling out to users over the next few weeks), you can go to facebook.com/appcenter on your desktop browser or m.facebook.com/appcenter on your mobile device to try it now.
– The App Center Facebook announced last month is open for business. The phased rollout will ultimately give all its US users access to 600 apps, like Pinterest and Draw Something, reports TechCrunch. Unlike Apple's App Store and Google Play, though, Facebook's App Center is more of a discovery hub, taking users to Apple or Google or elsewhere to download the apps. And, of course, Facebook's App Center puts the emphasis on sharing, recommending apps based on what your friends are using. Some early reaction: "In a sense, it’s a defining moment in the world of apps," writes Mike Isaac at All Things D. "Unlike the Google Play app repository or Apple's App Store, Facebook’s App Center relies in part on social discovery. And it’s in line with Facebook’s overall philosophy: Everything should be social." While noting the App Center should spur Facebook users to spend more time using the social network, "the focus on mobile apps is likely to attract criticism from those who see them as harmful to the future of the open web," notes Josh Halliday for the Guardian. "Conceptually, App Center seems like a winner to me," writes Jaymar Cabebe at CNet. "I found its recommendations helpful and the Friends' apps list very interesting, to say the least. On the other hand, the interface still has some kinks to work out, especially on mobile devices."
