Hi there! I see your Katasymbol app is crashing on your iPhone with iOS 18.6.2. Let's work together to get this sorted out.

To start me off, could you tell me a little more about the crashing? For example:
- Does the app crash immediately after opening, or after you perform a specific action?
- Have you tried any steps so far, like restarting your phone or updating the app?
- Are you connected to Bluetooth or any external devices while using the app?

Knowing these details will help me tailor the best solution for you. Meanwhile, here are some general steps that often resolve app crashes on iPhones:

1. Restart Your iPhone
Sometimes a simple restart clears temporary glitches. Press and hold the side button and either volume button, then slide to power off. After it's off, press and hold the side button until you see the Apple logo.

2. Update the Katasymbol App
Open the App Store, tap your profile icon at the top right, then scroll down to see if Katasymbol has an update available. Installing the latest version can fix bugs causing crashes.

3. Check for iOS Updates
Go to Settings > General > Software Update to confirm that your phone’s iOS is fully updated. Updates sometimes include fixes affecting app stability.

4. Clear App Cache / Data (if possible)
While iOS does not allow manual cache clearing like Android, you can try deleting and reinstalling the app to reset its stored data. To delete: tap and hold the app icon, select Remove App > Delete App, then reinstall from the App Store.

5. Check Bluetooth and Location Settings
Since Katasymbol may interact with Bluetooth devices (like label printers), ensure Bluetooth is on: Settings > Bluetooth. Also, enable Location Services if the app needs it (Settings > Privacy & Security > Location Services).

If you’ve already tried these or the crash occurs at a particular point, please let me know so I can dig deeper.

Are you able to share any error messages or specific behavior you noticed before the crash? That would be very helpful too.

Looking forward to your reply to help resolve this!
