From Nielsen:
When looking at U.S. smartphone users, women win the battle of the sexes in terms of time spent on media via apps and the mobile Web. In fact, while all smartphone users spent 89 percent of their mobile media time in Q4 2013 using mobile apps, women spent nearly an hour-and-a-half more than men using mobile apps.
