The iPhone as a Gaming Platform: Share of Top Apps By Category

As a follow-up to my recent post on the Top Grossing Apps list on iTunes, I examined three lists highlighted in the app store: the Top Paid, Top Free, and Top Grossing Apps. Believing that many users scan these lists, developers covet a spot on any of these Top 100 charts.

In my previous posts, I’ve highlighted that Games is the largest category, accounting for about 20% of unique apps. The graphs below show that the gaming category has a much larger share†† in each of the three Top 100 lists:


68% of the Top Paid, 67% of the Top Free, and 50% of the Top Grossing apps were Games. Other categories that had disproportionate share of apps in the Top 100 rankings include Social Networking, Photography, (and to a lesser extent) Sports, and Utilities.

In contrast, three of the five largest categories (Books, Travel, Education) were severely underrepresented in each of the U.S. iTunes Top 100 Charts.

(†) Size of a category is measured in terms of unique apps.

(††) Data for this post was from the two weeks ending 10/4/2009. I consider an app as being in the Top 100, if it was listed among the most popular (free, paid or grossing) apps, sometime during those two weeks.
