Facebook still the King of social apps when it comes to mobile viewing

While Facebook continues to dominate iOS and Android, on account of time spent by users on mobile devices, its lead has reportedly declined.

According to new data from app analytics service Flurry, the average US user spent an average of 2 hours and 42 minutes per day on mobile devices during the first three months of this year.

According to Mashable, Facebook and Instagram, which it acquired in 2012, accounted for 17 percent of that time, putting Facebook in the lead in the mobile space, but its share of time spent went down from 18 percent a year earlier.

Meanwhile, the amount of time spent on social apps in general ticked up year-over year from 24 percent to 28 percent, suggesting users are spending more time in other social apps, the report added.
