ChatGPT App Surges 148% to 450M Users, Downloads Hit 900M in 2025

ChatGPT's mobile app exploded in 2025 with monthly active users jumping 148% to 450 million and total downloads climbing 112% to nearly 900 million across Android and iOS platforms.

⬤ Fresh numbers from Similarweb show ChatGPT absolutely crushed it on mobile in 2025. The data compares worldwide Android and iPhone metrics for the full year 2025 against 2024, and the growth is massive. OpenAI's flagship AI app saw huge jumps in both monthly active users and store downloads.

⬤ Monthly active users skyrocketed 148.3% year-over-year. ChatGPT went from roughly 170 million MAUs in 2024 to around 450 million in 2025—more than doubling its user base. That's not a fluke spike; it's sustained global expansion across mobile platforms.

OpenAI Launches ChatGPT App Store With Native Third-Party Integrations

OpenAI just dropped the ChatGPT App Store, giving users a one-stop shop to browse and install third-party apps that work directly inside ChatGPT without ever leaving the conversation.

⬤ Downloads tell the same story. Total installs across both app stores climbed 112.6% year-over-year, jumping from approximately 420 million in 2024 to nearly 900 million in 2025. This steady climb throughout the year shows genuine demand, not just hype-driven bursts.
