ChatGPT app keeps crashing on startup
Your ChatGPT mobile app won't get past the loading screen, or it crashes within seconds of opening. This hits both iPhone and Android users, usually after an update or when your device is low on storage.
ChatGPT app keeps crashing on startup
Your ChatGPT mobile app won't get past the loading screen, or it crashes within seconds of opening. This hits both iPhone and Android users, usually after an update or when your device is low on storage.
What's actually happening
When the ChatGPT app crashes on startup, you're typically dealing with corrupted cache files, insufficient storage space, or a conflict between the app version and your operating system. The app tries to load your conversation history and user settings, but something in that process fails — so it shuts down before you even see the interface.
On iPhone, you might see a brief flash of the ChatGPT logo before the app closes and dumps you back to your home screen. Android users often get a "ChatGPT has stopped" error dialog, or the app just freezes on a white screen. Neither gives you any useful error code.
This happens most often right after OpenAI pushes an update, or when your device has less than 1GB of free storage. Your conversation history cache can also become corrupted if the app was force-closed during a sync, leaving damaged files that break the startup sequence.
How to fix it
1. Force close and restart the app
iPhone: Swipe up from the bottom (or double-click home button on older models), find ChatGPT in your app switcher, swipe it up to close. Wait 10 seconds, then reopen.
Android: Go to Settings → Apps → ChatGPT → Force stop. Wait 10 seconds, then reopen.
If it still crashes, move to step 2.
2. Clear the app cache and data
iPhone: You can't clear cache directly — skip to step 3.
Android: Settings → Apps → ChatGPT → Storage → Clear cache. Try opening the app. If it still crashes, tap Clear data (this logs you out but often fixes corrupted files).
3. Check your storage space
iPhone: Settings → General → iPhone Storage. You need at least 1GB free.
Android: Settings → Storage. You need at least 1GB free.
Delete old photos, apps you don't use, or offload data to free up space. The ChatGPT app needs room to decompress updates and cache conversations.
4. Update or reinstall the app
Check your app store for updates. If you're already on the latest version, delete the app completely and reinstall it fresh. This wipes corrupted files that survive a simple update.
iPhone: Press and hold the ChatGPT icon → Remove App → Delete App. Reinstall from the App Store.
Android: Settings → Apps → ChatGPT → Uninstall. Reinstall from Google Play.
You'll need to log back in to ChatGPT after reinstalling, so make sure you remember your credentials.
5. Update your operating system
Old iOS or Android versions sometimes conflict with newer app builds.
iPhone: Settings → General → Software Update.
Android: Settings → System → System update.
Install any available updates, restart your phone, then try ChatGPT again.
If that doesn't work
Your device might be too old for the current ChatGPT app version. OpenAI requires iOS 16.1 or later for iPhone, and Android 8.0 or later for Android devices. If you're running older software that can't update further, the app won't work — you'll need to use ChatGPT through your mobile browser at chatgpt.com instead.
If your device meets the requirements but crashes persist, report the issue through OpenAI's platform. Go to help.openai.com on your computer, click "Messages" in the bottom right corner, and describe the crash with these details: your device model, OS version, ChatGPT app version (from your app store listing), and whether you're a Plus or free user. Response times range from 24 hours to 4 days depending on support volume. You can find more information about contacting OpenAI support on our dedicated page.
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 locally on your device. They'll reappear after you log back in, though it might take a few minutes to sync.
Q: Why does it only crash on startup, but work fine once it loads?
A: The startup sequence loads your entire conversation index and checks for syncing issues. If those files are corrupted, the app crashes before the main interface appears. Once you get past that initial load, the app runs normally.
Q: Can I use an older version of the app that worked before?
A: Not reliably — OpenAI's servers eventually stop supporting outdated app versions, and you'll get forced to update anyway. Downgrading typically causes more problems with login loops than it solves.
What to remember
- Free up at least 1GB storage space before troubleshooting anything else
- Force close and clear cache before reinstalling — simpler fixes work surprisingly often
- Your conversation history won't disappear when you reinstall the app
- Devices older than 5-6 years might not support current ChatGPT versions
- Use chatgpt.com in your mobile browser as a reliable backup
