‘ComScore: Facebook Is Now the Most Used Mobile App in US’ – ‘Mashable’

Seth Fiegerman says, “Facebook is the most popular mobile app in the U.S. in terms of unique users — at least for now.

The signature Facebook app passed Google Maps in October of last year to become the most used mobile app in the U.S. and held onto the top spot through the end of the year, according to data released Wednesday by comScore Mobile Metrix.

Facebook’s app enjoyed strong growth in 2012 with 85.5 million monthly unique users in the U.S. in December across iOS, Android and RIM’s mobile platforms, up from just under 65 million in March, when comScore first started tracking mobile app data”.
