ChatGPT app keeps crashing on startup

You open the ChatGPT app and it crashes within seconds — a black screen, a freeze, or straight back to your home screen. This happens most often after iOS/Android updates, when your device is low on storage, or when the app's cache gets corrupted.

What's actually happening

The ChatGPT mobile app typically crashes on startup for three reasons: corrupted cached data inside the app, conflicts with your operating system version, or insufficient device resources. When you see the OpenAI logo flash and then disappear, that's usually cached data telling the app to load a state that no longer exists. If the app freezes on a white or black screen for 10+ seconds before closing, you're looking at a memory issue — your device can't allocate enough RAM to initialise the app properly.

Less commonly, crashes happen because your iOS or Android version is too old. OpenAI regularly drops support for older OS versions without announcing it prominently. If you're running iOS 15.0 or Android 10 and the app worked yesterday but crashes today, an automatic app update probably raised the minimum requirements.

Account-level issues rarely cause startup crashes. If you were banned or had payment problems, you'd get past the splash screen and see an error message. Pure startup crashes are almost always device-side problems.

How to fix it

1. Force-close and restart the app

Double-tap your home button (iPhone) or open recent apps (Android), swipe up on ChatGPT to fully close it, then wait 10 seconds before reopening. This clears the active session from memory. If it crashes again immediately, move to step 2.

2. Clear the app's cache

On iPhone: Settings → General → iPhone Storage → ChatGPT → Offload App (not Delete App). This removes the app but keeps your documents and data. Tap Reinstall App. Your login session stays intact.

On Android: Settings → Apps → ChatGPT → Storage → Clear Cache (not Clear Data yet). Reopen the app. If it still crashes, go back and tap Clear Data — this logs you out but forces a complete reset.

3. Check for app updates

Open the App Store or Google Play, search for ChatGPT, and tap Update if available. OpenAI pushes crash fixes within 24-48 hours of widespread reports. If you see "Open" instead of "Update", you're already on the latest version.

4. Verify your OS version

iPhone: Settings → General → About → iOS Version. You need iOS 16.1 or later as of January 2025.

Android: Settings → About Phone → Android Version. You need Android 11 or later.

If you're below those versions, update your OS through Settings → Software Update. If your device can't update that far (iPhone 7 and older, most Android phones from 2018 or earlier), the mobile app won't work. Use ChatGPT through your browser at chatgpt.com instead.

5. Free up storage space

The ChatGPT app needs at least 2GB of free space to function properly. Check Settings → General → iPhone Storage or Settings → Storage on Android. If you're under 2GB free, delete old photos, apps you don't use, or move files to cloud storage. Then restart your device and try the app again.

If that doesn't work

Delete the ChatGPT app completely (press and hold the icon, tap Remove App, confirm Delete). Restart your phone. Reinstall from the App Store or Google Play. This takes 3-5 minutes and forces the app to rebuild all configuration files from scratch.

Still crashing? The issue is likely on OpenAI's side. Check the OpenAI Status page at status.openai.com — if you see red indicators next to "ChatGPT Mobile App", they're already working on it. Outages affecting mobile apps usually resolve within 2-4 hours.

For persistent crashes after trying everything above, contact OpenAI support through help.openai.com/messages. Include your exact device model, OS version, and when the crashes started. Attach a screen recording if possible. Response times run 2-5 business days, but they prioritise widespread crash reports.

Questions people actually ask

Q: Will reinstalling delete my chat history?

A: No. Your conversations live on OpenAI's servers, tied to your account. Once you log back in after reinstalling, everything reappears.

Q: The app crashes only when I open a specific chat — why?

A: That chat contains content the current app version can't render — usually a malformed code block or corrupted image. Open ChatGPT on desktop at chatgpt.com, delete that conversation, then try the app again.

Q: Does ChatGPT Plus help with crashes?

A: No. Subscription status doesn't affect app stability. Free and Plus users run identical app code.

What to remember

  • Force-close the app and clear cache before reinstalling — saves your login session
  • You need iOS 16.1+ or Android 11+ as of early 2025
  • Keep at least 2GB of free storage space on your device
  • Chat history survives reinstalls — it's stored on OpenAI's servers, not locally
  • Check status.openai.com during widespread crashes — they usually resolve in hours, not days
