Some new numbers from Flurry Analytics. The data used was gathered by Flurry between January-March 2014.
From a Flurry Blog Post:
Time spent on a mobile device by the average US consumer has risen to 2 hrs and 42 minutes per day from 2 hrs and 38 minutes per day in March of 2013. Apps continued to cement their lead, and commanded 86% of the average US mobile consumer’s time, or 2 hrs and 19 minutes per day. Time spent on the mobile web [accessing content using a web browser] continued to decline and averaged just 14% of the US mobile consumer’s time, or 22 minutes per day.
Comparing them to last year, gaming apps maintained their leadership position at 32% of time spent. Social and messaging applications, including Facebook, increased share from 24% to 28%. Entertainement (including YouTube) and Utility applications maintained their positions at 8% each, while productivity apps saw their share double from 2% to 4% of the overall time spent.
Both Google and Facebook have very well established franchises on mobile, but the market is still very fragmented. In fact, Google and Facebook combined probably command less than 25% of the total time spent by the average US mobile consumer.
