Hi there! I see you're having trouble with the PulsePoint Respond app not responding on your iPhone. Let's work together to get that sorted out.

To start, could you tell me a bit more about how the app is behaving? For example:
- Is the app freezing, crashing, or simply not opening?
- Are you having trouble receiving notifications or updates within the app?
- Have you tried any troubleshooting steps already, like restarting your phone or reinstalling the app?

This will help me guide you better.

In the meantime, here are some common steps that often help with app response issues on iOS 18.5:

1. Force Close the App:
- Swipe up from the bottom of the screen and pause in the middle (or double-click the Home button if your device has one).
- Find the PulsePoint Respond app and swipe it upwards to close it.
- Reopen the app to see if it responds normally.

2. Restart Your iPhone:
- Hold down the power button and slide to power off.
- Wait about 30 seconds, then turn your phone back on.

3. Check for App Updates:
- Open the App Store, tap your profile picture on the top right, and scroll to see if PulsePoint Respond has updates available.
- Install any updates and try the app again.

4. Reinstall the App:
- Press and hold the PulsePoint Respond app icon until options appear, then choose “Delete App.”
- Re-download it from the App Store and log in again.

5. Check Network Connection:
- Make sure you have a stable internet connection (Wi-Fi or cellular data).
- Try switching between Wi-Fi and cellular to test.

If the app still doesn’t respond after these steps, it could be more specific like server issues or a deeper problem with the app or account settings.

Let me know which of these you've tried so far or if anything changes during this process! That way, I can guide you further or check if there are any known issues affecting PulsePoint Respond users right now.

Are you okay to try these steps and update me on what you see?
