Mobile App Revenue – iOS and Android (Broad Overview)

Although iOS has a smaller market share in comparison to Android, the former has led the way in revenue generation for app publishers. The main reason for this is that iPhone is widely popular and prevalent in high-income regions like North America, the UK, and Japan. Several pieces of research have indicated that people in these regions spend more on apps. 

Also, there are various app categories and genres on the App Store that drives consumer spending. However, gaming stands out as the biggest source of app revenue for Apple’s App Store

Talking about Google Play Store, the largest markets for this app store include India, South America, and Southeast Asia. All these regions typically generate less revenue per user. Also, the majority of the apps on the Play Store are free. The platform generates maximum revenue from games and in-app payments.

The Google Play Store is banned in China. But several third-party Android app stores operate in the country, amassing approximately $8 billion in revenue each year.
