A. To reduce crashes, ensure that your iPhone is running the latest version of iOS. Go to Settings > General > Software Update to check for updates. Also, try clearing the app's cache by uninstalling and reinstalling the app. This can help resolve any issues caused by corrupted data.

B. If the app continues to crash, try closing other apps running in the background to free up memory. You can do this by double-tapping the home button and swiping up on apps you want to close.
