If you’re asking for a Home Assistant device tracker integration that is an alternative to the Home Assistant integration for Life360, and you would like something that probably doesn’t require adding another app to your phone(s), I would suggest:
Google Maps - Home Assistant (home-assistant.io)
There’s a good chance your phone(s) already has/have this app installed. I’ll grant the integration is very old, and is a bit tricky to set up, but I’ve been using it for years and it pretty much “just works”.
