After that came a wide range of Google’s own apps, including Gmail, Maps, and Search. YouTube rounded out Google’s gaggle of apps dominating the top of the charts. As we reported previously, being able to control the user experience on those apps, as well as drive users to their services, is one of the main benefits to Google of creating the Android platform.
Angry Birds was the second most popular independent app, although the popular physics game scores better with 25-44 year olds then it does with the 18-24 year olds. The younger crowd prefers Pandora and Words with Friends to Angry Birds.
Gaming apps dominate across age groups, although music apps supplant some of that popularity among 18-24 yera olds. Other noteworthy trends include the Amazon AppStore, whose popularity increases the older a smartphone user is, and Advanced Task Killer, which seems to get less popular with the age of a user.
