Apps on one Apple Watch works in this way like apps on an iPhone or an iPad. If you close an app, it will remain active in the background.
Apple does this deliberately because restarting the app is then much faster. When the app is opened again, the content is immediately updated. It then seems as if the app was completely closed, but the app was not.
A Apple With watchOS, Watch handles the memory that an app takes up very efficiently Apple Watch. So it is not immediately necessary to completely close all apps on one Apple Watch.
However, some apps cause problems, such as crashes, not updating content or an application that drains your battery. Apple Watch deflates faster.
For reasons like this, you should force close apps and restart them completely. This is how it works.
Quit apps on a Apple Watch
To close an app on a Apple Watch to start by pressing the large button on the right side of the Apple Watch. You then open the 'Dock' with all active apps on your Apple Watch.
Then navigate to the app you want to close by swiping your finger from top to bottom or vice versa. You can also turn the Digital crown.
To close an app, swipe the app to the left with your finger. A red X button will then appear on the right side. Click the X button and the app will be force closed on your Apple Watch in watchOS.
You have now closed an app on a Apple Watch in watchOS.
Apple Restart watch
If an app crashes and force closing an app doesn't help, you can use the Apple Restart watch. Upon restart, all processes will be restarted and the app will function again.
Keeps on the Apple Watch the side button pressed again for at least 3 seconds (see image above). A 'Turn off' button will then appear. Swipe on the 'Turn off' button to turn off Apple Watch to close. Wait at least 10 seconds and restart Apple Watch again.
Apple Force watch restart
One way to restart the stuck app(s) or watchOS is to perform a force restart.
Press and hold both the digital crown and the side button at the same time for about 10 seconds. The Apple Watch will now restart and watchOS will restart.
