A. First, ensure that your iPhone's operating system is up to date. Go to Settings > General > Software Update and install any available updates. Outdated software can lead to compatibility issues that cause crashes.

B. If the app continues to crash, try uninstalling and reinstalling Snowbunny. To do this, press and hold the app icon until it wiggles, then tap the 'X' to delete it. After that, go to the App Store, search for Snowbunny, and reinstall it.
