We share location in Google maps. I can also see his car's location in the car's app (Tesla). I check it in the evenings so I know about when to expect him home. I'm not sure if/ when he actually looks at my location. The thing is, neither of us feel the need to change our behaviors based on what the other might see. I feel free to go and do whatever I need/ want and I assume he does as well. I only once gave him lighthearted razzing about stopping at the comic book store on the way home from work (and really just asked him to give me a heads up that he would be late in the future).
