ChatGPT app keeps crashing on startup

The ChatGPT mobile app opens for a split second, shows the logo, then immediately closes. This crash-on-startup issue affects both iOS and Android users, often after an app update or when switching between accounts.

What's actually happening

When the ChatGPT app crashes before reaching the login screen or chat interface, you're dealing with one of three core problems: corrupted cache data, insufficient storage space, or a conflict between your installed app version and your device's operating system.

The most common trigger is a failed update that left partial files on your device. When you tap the app icon, it tries to load these incomplete resources, can't reconcile them, and immediately terminates. You'll see the ChatGPT splash screen for 1-2 seconds maximum before returning to your home screen—no error message, no warning.

On iOS, this often happens after updating to a new version while connected to unreliable WiFi. The download completes, but verification fails silently. On Android, the problem frequently follows a forced app closure while ChatGPT was processing a large response or uploading a file. The app writes corrupted state data that blocks subsequent launches.

How to fix it

1. Force close and restart

On iPhone: Swipe up from the bottom (or double-click Home button on older models), swipe ChatGPT off screen. Wait 10 seconds. Relaunch.

On Android: Go to Settings → Apps → ChatGPT → Force Stop. Tap "Clear Cache" (not Clear Data yet). Relaunch.

If it crashes again immediately, continue to step 2.

2. Clear all app data

On iPhone: Go to Settings → General → iPhone Storage → ChatGPT → Delete App. This removes everything. Reinstall from the App Store. Sign back in.

On Android: Settings → Apps → ChatGPT → Storage → Clear Data. This resets the app to factory state without uninstalling. Relaunch and sign in.

Warning: This erases your custom instructions and any unsaved conversation drafts. Your chat history remains in your OpenAI account and reappears after login.

3. Check storage space

The app needs at least 500MB free to operate properly. On iPhone, check Settings → General → iPhone Storage. If you're under 1GB free, delete unused apps or old photos. On Android, Settings → Storage shows available space. Clear system cache from that same menu.

4. Update your operating system

The current ChatGPT app requires iOS 16.1 or Android 8.0 minimum. Older OS versions cause instant crashes because the app uses APIs those systems don't support. Update through Settings → General → Software Update (iOS) or Settings → System → System Update (Android).

5. Reinstall from scratch

If clearing data didn't help, completely uninstall the app. On iPhone, hold the app icon until the menu appears, select "Remove App", confirm "Delete App". On Android, Settings → Apps → ChatGPT → Uninstall. Restart your phone—this matters because it clears RAM and background processes. Then download fresh from the App Store or Play Store.

If that doesn't work

Your account may have a server-side issue preventing app authentication. Try logging in through chatgpt.com on your mobile browser. If that works but the app still crashes, contact OpenAI support with these details:

  • Your exact device model and OS version
  • The app version number (visible in your app store listing)
  • Whether you're on a Plus, Team, or Enterprise plan
  • Screenshot of Settings → Apps → ChatGPT showing storage used

OpenAI's mobile team typically responds in 2-4 business days. They can check server logs that show authentication failures invisible to you. If this crash affects multiple users on the same app version, they may release a hotfix within 24 hours.

Meanwhile, use the web interface at chatgpt.com—it has identical functionality except voice mode and iOS shortcuts. If you experience repeated login issues even on the web, your account may require additional verification.

Questions people actually ask

Q: Will I lose my conversations if I reinstall the app?

A: No. Your chat history lives on OpenAI's servers, not your phone. After reinstalling and logging in, all conversations reappear immediately.

Q: Why does it only crash when switching between work and personal accounts?

A: The app caches authentication tokens for multiple accounts. If one token expires or becomes corrupted, it crashes when trying to load that account. Clearing app data resets all tokens and forces fresh login.

Q: The app worked yesterday—what changed?

A: Auto-updates. Both iOS and Android can update apps overnight. Check your app store's update history to confirm. A buggy release can cause widespread crashes until OpenAI patches it.

What to remember

  • Force close and clear cache first—fixes 60% of startup crashes without losing data
  • Free up at least 1GB storage space before reinstalling
  • Update your OS if you're more than one major version behind
  • Your conversations are server-stored—reinstalling is safe
  • If crashes persist after reinstalling, report the specific issue with device details to OpenAI support
