U.S. iPhone users spent an average of $35 on apps (mostly games) in 2015

Last year, iPhone users spent an average of $35 on apps—both premium downloads and in-app-purchases—per active iPhone in the U.S., according to Sensor Tower Store Intelligence, which provides web-based analysis of downloads and revenue estimates for millions of app and thousands of publishers. These stats are approximately 110 million iPhones that were active in the U.S. during this period.

The figures in this report are based on estimate of 110 million active iPhone devices in the United States for calendar year 2015 (January 1 through December 31), as calculated by Sensor Tower using estimates from Consumer Intelligence Research Partners (CIRP) and additional panel-based sources. iPhone app download and revenue estimates for the corresponding period were produced by Sensor Tower’s Store Intelligence platform.

As the U.S. App Store’s largest category by revenue, it’s not surprising that Games comprised the majority of per-device spending during the first three quarters of last year, according to Sensor Tower Store Intelligence. On average, games accounted for approximately $25 of the $35 spent across the 110 million iPhones active in the U.S. during 2015. Second-place Music accounted for $3.40, or less than one sixth of Games.

Looking at app installs, the Games category was dominant here as well, with 10.5 apps downloaded on average per active iPhone in the U.S. That was more than two times the average number of apps downloaded for Photo & Video, the second-most-downloaded category with 3.4 per device.
