iPhone owners in the United States spent an average of $40 on apps last year, reports analytics firm Sensor Tower. That number includes both premium and in-app purchases, and it represents a $5 increase from 2015.
Unsurprisingly, most of that money is going to games. Sensor Tower says more than 80% of US App Store revenue in 2016 came from games, and it shows on the device level—users spent an average of $27 on games.
