A. 1. Reduce the zoom level: Instead of zooming in too much, try zooming in gradually. This can help prevent the app from crashing due to rendering issues. 2. Close other apps: Make sure to close any unnecessary apps running in the background. Double-tap the home button (or swipe up from the bottom on newer iPhones) and swipe up on apps to close them. This frees up memory for the Light Pollution Map app.

B. 3. Reinstall the app: Uninstall the app by pressing and holding its icon until it wiggles, then tap the 'X'. Reinstall it from the App Store to ensure you have the latest version.
