I had an idea for a location sharing app, years ago. Never built it. It would share privately using encryption, as this one does, but also, people could easily see a log of who looked up their location and precisely when. The benefit of this would be that you could ask your family members to install it on their phone, for emergencies. And if you have a teenage kid who is concerned about you "stalking" them or "invading their privacy", you will be able to say, "you will be able to see in the app whenever I look up where you are, so you will know that I'm not checking up on you constantly" It would also be a deterrant against you abusing your powers. You wouldn't want to look up where they are unless absolutely necessary, as you wouldn't want to create that log entry on their phone, as you'd have to explain it. Free idea, for anyone who wants it.
