Mobile analytics firm Flurry has processed data from more than 6bn app sessions on 500m smartphones and tablets in September 2012 to produce some research on how people are using these devices. It makes for interesting reading, with tablet owners skewing older and wealthier than smartphone owners, and an identifiable spike in usage in the evenings for tablets. Flurry also compares app usage by category, noting that games account for 67% of time spent using tablets, versus 39% for smartphones. Social networking is the second most popular category for both with 10% and 24% respectively. And music? Well, that falls into the ‘Other’ category that accounts for 11% of smartphone app usage and 7% for tablets. There are caveats here though: Flurry only tracks usage of apps that use its analytics tools, which means Facebook and Twitter aren’t included in the social networking data. Meanwhile, it’s unclear whether major music services like Pandora and Spotify are included, but Apple and Google’s native music apps certainly aren’t.
