State of AI Apps Report 2025

The analysis quantifies the rapid expansion of generative‑AI applications in the first half of 2025, documenting 1.6 billion downloads and $1.2 billion in in‑app‑purchase revenue. This represents a 67 percent increase in downloads and a 200 percent jump in revenue compared with the second half of 2024, indicating a pronounced acceleration in user adoption and monetisation. Engagement metrics rose in tandem, underscoring the sector’s heightened activity during this period.

User demographics reveal a pronounced male and youth bias: roughly 60 percent of users are male and nearly 70 percent are under 35. While flagship services such as ChatGPT and Google Gemini attract comparatively balanced audiences and exhibit strong cross‑app overlap, niche offerings—including Grok and DeepSeek—tend to cluster with privacy‑focused, crypto‑trading, and gaming user personas. This segmentation highlights divergent appeal across the generative‑AI landscape.

Advertising investment intensified, with OpenAI’s major campaign propelling it into the top‑ten spenders in key markets such as the United States, India and South Korea. AI‑driven ad creatives increasingly employ light‑hearted, animal‑centric visuals while emphasizing concrete everyday utilities, exemplified by Google Gemini’s car‑warning guidance and Microsoft Copilot’s quiz‑making and recipe‑generation tools. Spend estimates, tracked across U.S. platforms including Reddit, LinkedIn, TikTok and YouTube, illustrate the breadth of digital‑advertising channels leveraged.

Overall, the findings portray a sector experiencing explosive growth, a skewed yet evolving user base, and a surge in AI‑powered marketing activity across major global markets during H1 2025.
