"Our analysis shows that, for the first time ever, daily time spent in mobile apps surpasses desktop and mobile web consumption. This stat is even more remarkable if you consider that it took less than three years for native mobile apps to achieve this level of usage, driven primarily by the popularity of iOS and Android platforms. Let’s take a look at the numbers.
Flurry found that the average user now spends 9% more time using mobile apps than the Internet. This was not the case just 12 months ago. Last year, the average user spent just under 43 minutes a day using mobile applications versus an average 64 minutes using the Internet. Growing at 91% over the last year, users now spend over 81 minutes on mobile applications per day. This growth has come primarily from more sessions per user, per day rather than a large growth in average session lengths. Time spent on the Internet has grown at a much slower rate, 16% over the last year, with users now spending 74 minutes on the Internet a day."

Note on methodology:
"In this report, Flurry compares how daily interactive consumption has changed over the last 12 months between the web (both desktop and mobile web) and mobile native apps. For Internet consumption, we built a model using publicly available data from comScore and Alexa. For mobile application usage, we used Flurry Analytics data, now exceeding 500 million aggregated, anonymous use sessions per day across more than 85,000 applications. We estimate this accounts for approximately one third of all mobile application activity, which we scaled-up accordingly for this analysis.
