People Are Spending 3X More Time on ChatGPT App

The usage of ChatGPT’s mobile app has tripled since its launch and is now reaching around 20 minutes per day, according to data shared by investor Olivia Moore on X (formerly Twitter). The post included a screenshot from analytics firm Sensor Tower, showing a sharp rise in average time spent on the app.
OpenAI’s president and co-founder Greg Brockman shared this post by stating, “ChatGPT is becoming an increasingly important and useful part of people’s daily lives.” However, if we look closely, this is not an overnight rise. The company has been working to make its mobile app more intuitive by launching new features and capabilities time and again.
For example, recently, OpenAI rolled out GPT-4.1 to all ChatGPT Plus users, even to mobile users. GPT-4.1 comes with improved capabilities like code generation and instruction following, which may be contributing to longer and more frequent user sessions.
Along with the model upgrade, the company has delivered several mobile-specific improvements aimed at usability and performance. It includes:
- On Android, the app now supports larger in-line generated images by default, improving visual output. The keyboard in Temporary Chat mode has also been revamped to be more private and easier to use.
- On iOS, the update improved how users can interact with messages; long-press actions now allow quick copying and editing. Table copying has been made more seamless, and streaming of complex conversations, like nested blockquotes, is faster.
So, the 3x jump in engagement clearly signals growing traction for ChatGPT on mobile, a platform where usage behavior often differs from the desktop. How long this engagement continues to climb remains to be seen, but for now, mobile is proving to be a key part of ChatGPT’s growth story.
But it’s not just OpenAI focusing on mobile. Google recently launched a mobile app for its AI note-taking and research tool, NotebookLM, and also added the Gemini Live feature to its Gemini app. This shows that more people are using AI tools on their phones, and companies are responding to that growing demand.
