My family has moved to https://www.zood.xyz/ and it has been pretty solid. https://github.com/zood/ is the github repo for it.

There are more secure location sharing apps out there that are end to end encrypted. My family uses Zood location https://www.zood.xyz/ when we are out and about and needing to coordinate our locations. It is handy to use sometimes but it doesn’t do all the spy stuff the other apps do.
