For example, there will be an icon in the status bar that shows when an app follows your location.
However, it seems that with iOS 13, Apple will bring privacy to the next level not only by showing which apps are following you, but also the place where then followed you.
For example, in the picture above, the screen displays a permission request where iOS 13 will ask the user if they want to allow an app to continue to track their location in the background as well.
The option also comes with a small preview map in which it shows where the app has tracked your location.
In this case, the application in question is the Tesla app that makes sense to track your location after it is connected to the respective car.
This also means that if an app has followed your location when you do not want it, then you know something is wrong.
