( CNN ) -- According to comScore 's new Mobile Metrix 2.0 report released Monday , Facebook 's mobile usage is on the rise . In fact , the report revealed that Facebook users spent more time accessing the social network on smartphones than on computers in March . Facebook users spent an average of 441 minutes — or 7 hours , 21 minutes — accessing the social network via smartphones during the month . By comparison , users spent 391 minutes — or 6 hours , 31 minutes — checking out Facebook on PCs . The comScore report also revealed that smartphone users spent more time on Facebook than on any other social media network , including Twitter , LinkedIn , Pinterest and Foursquare . In fact , Facebook is the second largest mobile property behind Google . The social network garners more than 78 million unique monthly smartphone visitors , 81 percent of which access Facebook through its mobile app . Besides showing that people spend a good chunk of time on Facebook , the data underscores the importance of a mobile strategy for the social network 's business success . Facebook currently makes little revenue from its mobile app — the app does n't include ads , and only started to include `` sponsored posts '' in users ' news feeds last March . Facebook admitted its mobile struggles in its recent IPO documents . `` If users increasingly access mobile products as a substitute for access through personal computers , and if we are unable to successfully implement monetization strategies for our mobile users , '' the company writes in its filing documents , `` our financial performance and ability to grow revenue would be negatively affected . '' In light of these stats , a Facebook smartphone makes all the more sense . The company could capitalize on its mobile leadership position . But because Facebook has not officially made any announcements about its hardware plans , it 's unclear when a Facebook phone will actually enter the market . In the meantime , we can hope that the company continues to update its mobile apps . Subscribe to WIRED magazine for less than $ 1 an issue and get a FREE GIFT ! Click here !
