Facebook platform sent 160M users to mobile apps in April

Facebook says it sent more than 160 million visitors to Facebook-integrated mobile apps last month, according to a post on the company’s developer blog.

Native mobile games like Zynga’s “With Friends” titles, popular apps from Spotify, Pinterest and now Viddy and Socialcam are among those that benefit from Facebook’s mobile discovery channels. The social network’s mobile platform also helps web apps like the Washington Post Social Reader, Flixter and BranchOut.

Visitors from Facebook accounted for 1.1 billion visits to iOS and HTML5 apps, meaning an average of more than 6 visits per user. These numbers are up from February when Facebook said it drove 60 million users to mobile apps an average of about five times per month. Next month is likely to be much higher since the social network began supporting mobile discovery for native Android apps last week.

Facebook says iOS video sharing app Viddy now has more than 16 million registered users, in part because of Open Graph integration that shares user activity between the mobile and desktop versions. Because of similar functionality, networking web app BranchOut has seen more than 18 million people come in from the social network in the past 28 days. Facebook also highlighted movie review and info mobile web app, Flixster, which has seen a tenfold increase in the number of visitors from Facebook in the past four weeks. These visitors generated a total of 15 million visits in the same period.

Facebook also made a point in its blog post that seven of the top 10 grossing iOS apps and six of the top 10 grossing Android apps integrate with Facebook through single sign-on or Open Graph.

Facebook’s mobile platform allows HTML5 and native iOS and Android apps to get distribution through News Feed, bookmarks and requests. When users navigate to mobile app links from Facebook, the appropriate native app will open on a user’s device or lead to a download page if the user doesn’t have it yet. Developers also have the option to integrate Facebook Open Graph, which lets games automatically publish stories about user activity, including reaching a new high score, leveling up, earning an achievement or surpassing another friend playing the game. These stories are distributed through mobile Timeline and News Feed and can drive traffic back to a mobile game.

Facebook has more than 500 million monthly active users accessing the site through mobile devices, according the company’s updated filing for an initial public offering. The social network does not offer a breakdown of how many of those mobile users are using iOS or Android devices that can access these apps.
