What about locus maps? I did not look into the location sharing but there are many options according to https://docs.locusmap.eu/doku.php?id=manual:user_guide:functions:share. It is a paid App but it is really great. I use it all the time for hiking.
Edit: There is also owntracks (https://owntracks.org/) which loggs your location history. The Website can than be shared with whom you like.
Yep thanks Yahoo, disgusting… Donated some so that they can pay the employes and thinking about getting a metager key.
