TikTok was the top grossing app worldwide for the fourth year in a row and generated more than $3 billion in-app, the only app on the market to reach that milestone.
It is a major feat for the video sharing app, which has continued growing its revenue and users despite the imminent threat of sale for its US division. About 40 percent of TikTok’s total in-app revenue came from the United States, with Germany and Japan the app’s second and third largest markets for in-app purchases, according to data from AppMagic.

Even though TikTok gets all the glory for being the top grossing app, it will have a formidable opponent in the future in ChatGPT, which increased its in-app revenues by 515 percent in 2025 to $2.3 billion. It was the third most grossing app worldwide in 2025.
Google One, the company’s cloud storage app, had another year of strong in-app revenue growth, going from $1.7 billion in 2024 to $2.6 billion in 2025. It was the top grossing Google Play app by a decent margin, earning almost all of its revenue from that platform. It was also the top grossing app in the United States, with $1.5 billion coming from that country.
In terms of games, Honor of Kings was once again the top grossing game worldwide, even though it is only available in China. The League of Legends clone developed by Tencent has been the top grossing game for four years now, but in-app revenues have declined from $1.8 billion in 2024 to $1.6 billion in 2025.
Games in general had lower in-app revenues than the previous year, highlighting a shift in user spend from games to apps. Several major apps such as YouTube, Tinder, Duolingo and CapCut increased their in-app revenues in 2025.
