According to Flurry Analytics, overall app use in 2013 posted 115% year-over-year growth. (In this context, we define app use as a consumer launching an app and recording what Flurry defines as a session.)
Every single app category has shown growth over the last twelve months. In the chart below, we have focused on the categories of interest to most. Utilities and Productivity apps posted 150% growth in use year-over year, as smartphones and tablets became personal computers and productivity apps, such as Evernote and Quip, gained sophistication and adoption. Even Gaming, which was feared to reach saturation levels in 2013, posted 66% year-over-year growth in use.
