Organic Maps (Unofficial)

I did misunderstand slightly but this might be better.

I mistook organic maps for open street maps itself but what i am looking for is in fact a front end. But one i can host on a local server so familymembers can access it on their browser or a app.

The map i would host would still be osm but my guess now is that any modifications like routes and pins would count as a second map in a top layer that i possibly could host?

Anyway i am convinced organic maps does solve my problem for ios mostlly.

One way i think i could pull off the functionality is by simply having a shared osm account logged in organic but that defeats the purpose of my server where such data is local.
