I recently asked my Wife if She would like me to activate the "find my friendships" function on my phone - by permanently sharing my location with Her - so that She always knows where I, Her property, am. She paused a second or so and said " that would be nice - I can keep an eye on you all the time". So I shared my location with Her and whenever I am, at any time, She can see. I can't "unshare" as Her phone will tell Her I have. She says She likes it as its an extension of my chastity and commitment to Her. I love knowing She can keep any eye on me this way.
Forgot to say - needless to say She does not share Her location with me, rightly so, I have no need or right to know where She is!
I've setup an App "Life360" for this. The good thing is, that it's possible to enable alarms if someone enters or leaves an area. Additionally it's possible to look into the timeline where and how long someone has been at a certain location and the traveltime in between. Love it. The only downside are that the location is also shared with the company hosting this app (privacy concerns).
I use this app, it's only for iPhones though: https://tracky24.com/index.php/login You can see a 3 day history of where they have been, and you can get them to do interesting things for you
Madam and I tried quite a few apps for this and as we both have iPhones forms the find my friends app the best.
Afaik I run into issues before I disabled Battery Optimization for this app (as you might need to do with other apps which should still run in the background).
My Mistress uses Norton Family to control and restrict my internet usage. The phone app comes with a tracking function which I know is turned on. I don't know however if my Mistress ever check where I am. But I love knowing she can check my location at all time
My Mistress requires that I have Life360 installed. I can't see her location but She can see mine. It also provides her with my driving statistics and I get punished if breaking any of her rules. I have tagged my most common locations (home, work supermarket) and I must request permission before venturing anywhere else. I believe She receives an alert whenever I arrive at a tagged location. It works well for us.
My wife keeps an eye on me with Find My Friends as well. I go on business trips somewhat often, and there is the practical aspect of her knowing where I am and that I'm safe. But it definitely keeps me out of trouble too. When I'm in Vegas I have to ask her permission before I go see show girls or anything risque.
