ChatGPT’s mobile app, once the fastest-growing AI-powered application worldwide, is now experiencing a noticeable slowdown in download growth and daily active usage, according to recent data from app intelligence firm Apptopia. After an unprecedented surge in early 2023 and 2024, the global percentage increase in new downloads has been tapering off since April 2025. More strikingly, daily active users (DAUs) have leveled out in recent weeks, suggesting the app’s user acquisition pace has peaked.
Despite the slowing percentage growth, ChatGPT’s mobile app continues to see millions of downloads daily, indicating that the total number of users is still expanding but at a reduced momentum. Apptopia’s figures reveal that downloads are projected to fall 8.1% month-over-month in October 2025, compared to previous months’ gains. This stagnation may be attributed to intensified competition among AI chat apps and changes to the underlying AI model affecting user engagement.
Further insights from the US market reveal significant declines in how users interact with ChatGPT’s mobile app. The average time spent per daily active user dropped 22.5% since July 2025. Sessions per user also decreased by 20.7%, indicating that even loyal users now spend less time and open the app less frequently throughout the day. However, user churn has stabilized, showing that the app retains its core audience even as casual users become less engaged.
ChatGPT’s initial explosive growth broke records, reaching over 1 million users just five days after its November 2022 launch and hitting 100 million monthly active users within two months. By mid-2025, the app boasted between 700 and 800 million weekly users worldwide, solidifying its status as a dominant AI platform. However, as growth matures and the AI app market saturates, maintaining user interest and expanding usage remain critical challenges.
Industry experts suggest that rising competition from new AI-powered chat applications and diversified user needs could be contributing to the slowing growth. Additionally, evolving AI models could impact user experience and expectations, requiring continuous innovation from OpenAI to keep ChatGPT relevant. Meanwhile, the broadening use cases of AI, beyond productivity to lifestyle and entertainment, indicate shifting user behavior patterns that may require App updates and feature expansions.
In response, OpenAI has been actively rolling out updates and introducing integrations with other services through its new apps SDK, aiming to expand ChatGPT’s utility. While growth slows, the app’s substantial user base and heavy daily traffic provide a solid foundation for future development. It remains to be seen how OpenAI will counteract these trends with new features and engagement strategies to reignite download growth and user activity.
Key Takeaways:
- ChatGPT mobile app’s download growth has slowed down considerably since April 2025.
