Nearly 40% Of Facebook Users Are Mobile App Users

According to new data from Benedict Evans for Enders Analysis, the number of monthly active users of Facebook’s mobile apps recently passed the 300 million mark. This is primarily due to heavy use of the iOS and Android apps, but it also takes into account apps that run on BlackBerry, Symbian, Windows Phone, iPad and feature phones.

That number equates to roughly 40% of Facebook’s currently disclosed 800 million active users.

What’s interesting is that Facebook announced in September that over 350 million active users access Facebook through their mobile devices – a number that includes mobile web users as well as users of its mobile apps. Explains Evans, you can track the number of app users by going to the Facebook Page for each app then adding them up. (Alternately, one could use a service like AppData to do something similar).

At the time that Facebook announced 350 million mobile users, there were 250 million mobile app users, he says. That means that over the past few months, Facebook has seen another 50 million+ become active app users. Impressive.

Evans’ findings also back up TechCrunch writer Josh Constine’s earlier report that Android has finally surpassed iPhone in terms of daily active users. But on a weekly and monthly basis, iPhone and iPod Touch are still coming out ahead. In fact, in terms of monthly active users, over 100 million are using iPhone/iPods, says Evans. (The iPad is broken out separately).

BlackBerry devices and feature phones are still somewhat holding their own, while Symbian and the practically insignificant contributions from Windows Phone trail the number of iPad users whether you’re looking at daily, weekly or monthly active user counts.

One thing we don’t know – and can’t know, unless Facebook itself reported it – is how many users only access Facebook on their mobile phone, never visiting the desktop site. Evans estimates that number is high, but it’s impossible to tell using currently published data.
