Restart iPhone:

Simple but effective. Restart clears memory and stops problematic processes. Should be your first troubleshooting step.

Update the App:

Open App Store > Updates. Install pending updates. Developers fix crash bugs regularly.

Update iOS:

Settings > General > Software Update. Updated iOS improves app compatibility. Security patches also included.

Delete and Reinstall App:

Long-press app > Remove App > Delete. Reinstall from App Store. Fresh installation often resolves issues.

Free Up Storage:

Settings > General > iPhone Storage. Low storage causes crashes. Delete unused apps and files.

Reset All Settings:

Settings > General > Reset > Reset All Settings. Doesn't delete data but resets system settings. Often fixes stubborn issues.

Conclusion:

Updates and reinstallation solve most crashes. iOS apps are generally reliable—persistent issues may indicate hardware problems.
