Update: Thanks to everyone for weighing in about the infographic. The data used was given to us on an exclusive basis from analytics firm Flurry. Indeed, three-quarters of the apps in the App Store are “paid apps,” which was used to calculate the average app price and the subsequent revenue figures in the previous version. However, only one-quarter of the apps actually downloaded are “paid apps,” so the average price per transaction (paid + free downloads) is actually much lower than the average app price in the store. The graphic has been updated to reflect this price. Also, some of the averages in the Flurry data were calculated using projected user numbers from the first quarter 2010; that has been corrected to reflect only data up to the end of the year.

For clarification purposes, here is the math:

According to Flurry, Average listed price of a paid app: $3.63

74% of apps listed in the app store are paid. Average listed price of an app (including free): 3.63 x .74 = 2.70 (with rounding)

Only 1/4 of downloaded apps are paid. Average price paid for  an app (including free): 3.63 X .25 = .91
