The number of active users who access Facebook every month via a mobile application has just passed 300 million, according to Benedict Evans from research company Enders Analysis.
He notes that Facebook announced 350 million mobile users in total a few months ago, from an overall total of 800 million users. At that point, Benedict says there were around 250 million monthly active users of mobile apps, which meant 70% of mobile users were accessing Facebook via apps.
Around half of all Apple iOS and Android users are thought to have installed the Facebook app, along with 70% of active BlackBerry users.
