I've been using OwnTracks for years now with no issues. I disabled battery optimization for it. Granted, I don't have a phone made by a manufacturer that has decided to add garbage to the OS to aggressively kill background apps.
Only annoyance is Android has a thing where it doesn't allow apps that start on boot to automatically start getting GPS data, so on every boot you have to tap a notification to kick things off.
Which phone manufacturer is that? I hate having to remember all the apps I disable battery optimization for. I think I currently have like 5 apps or so.
