Hi there! I understand that your CoinGecko app isn't responding, while everything else seems to be working fine on your device. Let’s see if we can get this sorted out together.

First, can you let me know if you’ve tried any troubleshooting steps already, such as restarting the app or your device? Knowing this will help me guide you effectively.

In the meantime, here are some initial steps you can try:

1. Force Stop the App:
- Go to your device's settings.
- Find "Apps" or "Application Manager".
- Look for CoinGecko in the list and tap on it.
- Tap "Force Stop," then restart the app.

2. Clear Cache:
- In the same app settings, you can also tap on "Storage".
- Here, you’ll find an option to "Clear Cache". This can help refresh the app’s performance.

3. Check for Updates:
- Open the Google Play Store.
- Search for CoinGecko and see if an update is available. If so, install it.

4. Reinstall the App:
- If the above steps don’t work, uninstall the app and then reinstall it from the Google Play Store.

Try these steps out, and let me know how it goes! If the issue persists, we can explore more specific solutions.
