Hey there Blood_Brother,
Thanks for reaching out to the Apple Support Communities. To get started, do you experience performance issues with all apps, or just specific third-party apps?
If the issue is occurring with specific apps, give the steps listed in the following resource a try: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support
1. Close and reopen the app
Force the app to close. Then open the app to see if it works as expected.
2. Restart your device
Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.
3. Check for updates
To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.
4. Delete the app, then redownload it
Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.
