The mobile app is available on iOS and Android through their app stores.

  2. Search "ChatGPT" and install the official OpenAI app.

Syncing Chats Across Devices 

This part explains how your conversations stay available no matter which platform you use.

Chats sync automatically across web, desktop, and mobile as long as you're logged into the same account — no manual syncing needed.

Example: Start a chat on your phone during a commute, then continue it later on your laptop's desktop app — the full history carries over instantly.

Conclusion

Web works everywhere with no install, desktop adds speed and shortcuts for daily computer use, and mobile adds camera and voice access on the go. All three stay in sync automatically, so switching between them never loses your chat history.
