A. 1. Ensure your iPhone is running the latest version of iOS. Go to Settings > General > Software Update and install any available updates. 2. Close other apps running in the background to free up memory. Double-click the Home button (or swipe up from the bottom on newer iPhones) and swipe up on apps to close them. 3. Delete and reinstall the Blurrr app. This can clear any corrupted data that might be causing crashes. 4. If the app continues to crash, try resetting your iPhone's settings by going to Settings > General > Reset > Reset All Settings. This won't delete your data but will reset system settings to default.
