Hello, nwright_1998.
Thank you for using Apple Support Communities.
From reading your post, you have some questions about using two apps but only having one of them display. Currently, the Apple Watch runs apps primarily in the foreground: Running watchOS Apps in the Background
"Apps on watchOS primarily run in the foreground in order to limit the impact on system resources. However, there are times an app needs to run even though it is not the foreground app. WatchOS allows an app to run in the background in specific instances, such as when:
- Your app must perform work while suspended. The system launches or wakes the app up and gives it a small amount of time to run in the background.
- The app requests to run in the background because of certain features. Apps that support workouts or audio playback can stay running in the background until the workout or audio playback finishes. If the app uses location services, the system will launch or wake it up in the background when a location update comes in".
You may need to reach out to the App Developer about the Golf workout app running in the background: How to contact an app developer
Best regards.
