Today I had to share two GPS locations with people that most probably does not use #OpenStreetMap based maps or apps. Because of the really low support for the geo: URL scheme https://wiki.openstreetmap.org/wiki/Geo_URI_scheme, this means that the best way to provide a link is with a GMaps link :(((
I found the #OSMApp https://osmapp.org/ can provide links for several maps providers. I find this app more and more useful.
