My plan is to open the garage door, right when she gets home 
Worked great.
On my Android phone, not only is Google Maps installed by default, it can’t be uninstalled.
While I can’t speak to exactly what signals the iPhone sends that allow “Find My” to work, the AirTags and other similar items are passive devices. They don’t know where they are, ever. When someone with an iPhone gets near an AirTag, it makes a note of what tag it saw, references that against its own calculated location, then sends that data along to Apple. So they’re effectively outsourced the “find” part.
I'm sorry, Dave, I can't let you do that.Give it another 2 years. But truely, I do worry about my wife when she is alone hiking or riding. It’s sort of my job.
