Hi! I’m sorry to hear that your Color Number app keeps crashing. To help get to the bottom of this, could you tell me a bit more? For example, does it crash right when you open it or during certain actions? Also, have you tried any troubleshooting steps already like restarting your iPhone or reinstalling the app?

In the meantime, here’s a simple step-by-step plan we can try:

1. Restart your iPhone: This can clear temporary glitches. Just hold the power button and slide to power off, then turn it on again.

2. Update the app: Check the App Store to see if there’s an update available for Color Number. Updates often fix bugs.

3. Reinstall the app: Tap and hold the app icon, choose Remove App, then delete it. After that, reinstall from the App Store. This clears app data that could be causing crashes.

4. Check your device storage: Low storage can cause apps to crash. Go to Settings > General > iPhone Storage and make sure you have enough space.

5. Update your iPhone’s iOS: You mentioned your iOS version is 18_7, which sounds like iOS 18.7, so it’s likely current, but just double-check in Settings > General > Software Update.

If you’ve already tried some of these, please let me know which ones so we don't repeat steps. If the crashes continue after this, I can guide you through more advanced options or check if there are any known server issues at that time.

Would you like to try these first steps and then tell me how it goes?
