I live in Argentina and use OpenStreetMap since the maps are really accurate in that area.
I travel in a specific area with my Android Smartphone using GPS. In that area mainly I like to save GPS coordinates in my map (my clients) and make notes to them. Additionally I would like to add roads that are not recorded in OpenStreetMap yet, but that is not really necessary.
Currently I use the Osmand app on my phone. It contains offline maps, which is important since I have no internet connection out there, I can record favorites but cant really make much notes to them like some kind of history of my visits. And I cant extend the map of unknown roads with that app.
Is there a better way to achieve that?
I would like to use the favorites to see where I have to make my visits next and what would be the best route for that.
