Hi! I understand the Days Until app won’t open on your iPhone running iOS 18.6. Let’s work through this together to get it up and running.

First, can you tell me a bit more?
- When you tap the app icon, does anything happen?
- Does it crash immediately or just stay on the loading screen?
- Have you tried any steps already, like restarting your phone or updating the app?

While I wait for your details, here are some initial steps you can try:

1. Force close the app:
- Swipe up from the bottom of your screen and pause in the middle (or double-click the Home button if your iPhone has one).
- Find the Days Until app preview and swipe it up off the screen to close it completely.
- Then try opening it again.

2. Restart your iPhone:
- Press and hold the side button and either volume button until the slider appears.
- Slide to power off, wait 30 seconds, then press the side button to turn it back on.

3. Check for app updates:
- Open the App Store.
- Tap your profile icon at the top right.
- Scroll down to see if Days Until has an update waiting. If yes, tap Update.

4. Reinstall the app:
- Touch and hold the Days Until app icon until a menu appears.
- Tap Remove App > Delete App to uninstall.
- Then go back to the App Store and reinstall it.

If these don’t fix the problem, please let me know exactly what happens when you try opening the app. We can try some advanced troubleshooting from there.

Are you comfortable trying these steps now?

Won’t launch

Thanks for letting me know it still won’t launch. Since the initial steps didn’t help, let’s try a few more detailed troubleshooting actions on your iPhone with iOS 18.6.

1. Check Storage Space:
Go to Settings > General > iPhone Storage and see if you have enough free space. If the storage is nearly full, it can prevent apps from opening properly.

2. Check App Permissions:
Go to Settings and scroll down to Days Until. Make sure it has the necessary permissions to run, like access to notifications or calendar.

3. Reset Network Settings:
If Days Until depends on internet data, resetting your network settings can help.
- Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- Note that this will erase saved Wi-Fi passwords, so be prepared to reconnect.

4. Check for iOS Updates:
Go to Settings > General > Software Update and confirm you are fully updated to iOS 18.6 or any patches beyond.
<br5. Check for App Conflicts:
If any new apps were installed recently, sometimes conflicts happen. Try closing other apps running in the background and then open Days Until.

6. Contact Support or Report Bug:
If none of these help, it might be an issue with the app version on iOS 18.6. Let me know if you want me to connect you to Days Until’s technical team for deeper investigation.

Could you try these and tell me what you find? I’m here to help get this sorted out with you.

Common problems with Days Until app launch

Thanks for asking about common issues with app launches like Days Until. Based on general knowledge of mobile app startup problems and optimization, here are some typical causes that can make an app fail to launch or crash immediately:

1. Excessive resource loading on startup: The app might be trying to load too many files or data at launch, especially large images, videos, or network calls, which can overwhelm the device1 7.

2. Bugs or crashes in the app code: UI bugs, functional errors, or crashes within the app’s programming can sometimes cause it to close immediately upon opening2.

3. Slow or failed network connections: If the app relies on internet access to load essential data before showing you the screen, a poor or missing connection may prevent it from opening properly2.

4. Compatibility issues: Sometimes apps have trouble launching on specific OS versions or device models because of missing updates or deprecated features.

5. Conflicts with other apps or corrupted app data: Other apps running in the background or corrupted files within the app’s storage can also interfere with startup2.

For the Days Until app on your iPhone with iOS 18.6, since it won’t launch at all, it could be linked to any combination of these. We’ve already tried basic fixes like reinstalling and restarting the iPhone. If this persists, I recommend contacting the Days Until developer support. They can check if there’s a known bug related to your iOS version or device and provide an update or patch.

If you want, I can guide you on how to reach their support team or help check for any official announcements about this issue. Would you like me to do that?
