TikTok, including its Chinese counterpart Douyin, in 2024 became the first non-game app to reach $6 billion in in-app purchase revenue in a year, according to a new report from app intelligence provider Sensor Tower. With its $6 billion in IAP revenue, TikTok generated more than double the revenue from any other app or game in 2024. By downloads, however, TikTok was only No. 2 in Q4 2024, with Instagram at No. 1.
