ChatGPT app keeps crashing on startup

The ChatGPT mobile app crashes within seconds of opening, or gets stuck on the loading screen and then closes. This hits both iOS and Android users, often right after an update or when you haven't opened the app in weeks.

What's actually happening

App crashes on startup usually mean corrupted cache data, compatibility issues with your device's OS version, or authentication tokens that expired while the app was closed. The app tries to verify your session, can't reconcile the stored data with OpenAI's servers, and gives up by shutting down.

On iOS, you might see a brief flash of the chat interface before everything goes black. On Android, the app sometimes displays "ChatGPT has stopped" or just returns you to your home screen without any error message. Some users report the OpenAI logo appearing for 2-3 seconds before the crash — that's the authentication handshake failing.

If you recently updated the app or your phone's operating system, the crash often comes from incompatible cached data that the new version can't read. The app doesn't always clear old data during updates, so it chokes on outdated session information.

How to fix it

1. Force close and clear from memory

On iOS: Swipe up from the bottom (or double-click home button), find ChatGPT in the app switcher, swipe it upward to close completely. On Android: Open recent apps, swipe ChatGPT away or tap the X.

Wait 10 seconds, then reopen. If it still crashes, move to step 2.

2. Clear the app cache

On iOS, there's no built-in cache clear — you'll need to offload the app. Go to Settings → General → iPhone Storage → ChatGPT → Offload App. This removes the app but keeps your login data. Tap "Reinstall App" when it finishes.

On Android: Settings → Apps → ChatGPT → Storage → Clear Cache (not Clear Data yet). Try opening the app. If it crashes again, go back and tap Clear Data — this logs you out but usually fixes the crash.

3. Update or reinstall the app

Check the App Store (iOS) or Google Play (Android) for updates. If you're already on the latest version, delete the app completely and reinstall fresh. This forces a clean authentication flow when you log back in.

After reinstalling, don't restore from backup immediately if you're on iOS — set up as new first to rule out corrupted backup data.

4. Check your device compatibility

ChatGPT requires iOS 16.1 or later, and Android 8.0 or later. Go to Settings → General → About (iOS) or Settings → About Phone (Android) to check your version. If you're running an older OS, you'll need to update your phone or switch to the web version at chatgpt.com.

Some older devices (iPhone 7 and earlier, Android phones from 2017 or before) struggle even with OS updates installed. The app is resource-heavy and won't run smoothly on limited RAM.

If that doesn't work

The crash might be server-side. Check status.openai.com for outages — if "ChatGPT Mobile" shows degraded performance or an outage, you'll need to wait for OpenAI to fix it.

If the status page is green and you've tried everything above, you're likely hitting an account-specific issue. Contact OpenAI support through help.openai.com — include your device model, OS version, the exact moment the crash happens (loading screen, after login, when opening a chat), and whether you're on a free or paid plan. Response times run 24-48 hours for most issues, longer if there's an ongoing outage.

Some users find switching between accounts helps identify the problem — if you have access to a second ChatGPT account, try logging in with that. If the second account works, your original account might have corrupted conversation history that crashes the app when it tries to load.

Questions people actually ask

Q: Will I lose my chat history if I reinstall the app?

A: No. Your conversations are stored on OpenAI's servers, not your phone. You'll see everything again after logging back in, unless you've disabled chat history in your settings.

Q: The app worked fine yesterday — why is it suddenly crashing?

A: Usually an automatic app update that your phone installed overnight, or an expired authentication token. Try clearing cache first before a full reinstall.

Q: Can I use ChatGPT while this gets fixed?

A: Yes — go to chatgpt.com in your mobile browser. You'll have full access to all features except voice input, which requires the app. For more options, see how to fix ChatGPT not working.
