Facebook has announced that its App Center is now live in the US, Australia, Canada, India, Ireland, New Zealand, South Africa and the UK.
"People in these countries will now see the App Center bookmark on the left side of their home page on Facebook.com and in the Facebook apps for iPhone, iPad, and Android," Facebook said in a statement.
It is also available via facebook.com/appcenter.
Given that about 80 per cent of active Facebook users each month are located outside the US, the social network said App Center will roll out to additional countries in the coming weeks. That includes Brazil, France, Germany, Russia, Spain, Taiwan and Turkey.
Facebook unveiled its App Center in early June with 600 social apps, including Nike+ GPS, Ubisoft Ghost Recon Commander, Stitcher Radio, Draw Something and Pinterest. At the time, Facebook announced plans for a phased rollout, beginning in the US.
The company pointed to game developer Kixeye, which saw a boost in installs and found that App Center traffic produces better than average revenue per user for its games War Commander and Battle Pirates. Disney's Marvel: Avengers Alliance also found that App Center users are more engaged than those who download from other stores, Facebook said.
Facebook is now accepting submissions for translated apps. Those who want to have their apps included in the rollout to new countries must submit by 13 July. More details are available on Facebook's blog.
Facebook encouraged international submissions and pointed out that some of its most popular apps and games, like Diamond Dash, Angry Birds Friends and Spotify, have been built by non-US developers.
In related news, the Wall Street Journal reported that a new mobile ad effort from Facebook will be based on the apps used by its members. Facebook will track the usage of apps accessed via Facebook Connect - like Yelp or Amazon - and target apps based on that usage, the Journal said. Facebook has not yet decided whether to target based on activity within an app.
