Or even better, when you’re get inside a diameter of x meters around it.
Are any of them a thing?
Geofencing is the term to search for. Here’s an example: https://fossdroid.com/a/nexttracks.html (don’t know if it is any good, it was just the first I found)
Tasks is able to set reminders when entering or leaving a location. Just add a task with the + on the homescreen, set a location (enable permission for Tasks), click on the bell besides that and define other parameters like name etc. Tadah.
I tried that before on android 10 and it didn’t work. Maybe it’ll work on my android 13 rn.
Its not FOSS, but with Tasker its possible and with AutoLocation its easier to do. I have mine check where I am everytime I disconnect from my car’s bluetooth, and run tasks based on where I am (work, home, etc)
