Hello! I’m Grace, here to help you with the Elephant Meters app issue on your iPhone. Let’s get this sorted out together.

To start, could you tell me a bit more? For example:
- When you try to open the app, do you see any error messages or does it just stay on a loading screen?
- Have you recently updated the app or your iOS to version 15.8.5?
- Have you tried restarting your iPhone or reinstalling the app already?

Meanwhile, here's a straightforward approach we can try:

1. Close the app completely: Double-click the Home button (or swipe up from bottom if your iPhone model doesn’t have a Home button), then swipe the Elephant Meters app off the screen to close it.

2. Restart your iPhone: Hold down the power button, slide to power off, then turn it on again.

3. Check for updates: Go to the App Store, tap on your profile icon, and see if there’s an update for Elephant Meters. Also, check if iOS updates are available under Settings > General > Software Update.

4. Reinstall the app: If the issue persists, delete the Elephant Meters app by holding its icon until it wiggles, then tapping the X or Remove App. After that, reinstall it from the App Store.

Let me know if any of these steps help or if you encounter anything else along the way. We’ll go from there!
