We all need to contribute to open maps in order for then to be actually usable. Some parts don't have any street numbers, and some don't even have street names, much less business info on them.
EDIT: We also should contribute to the open maps lemmy community and help out.
Organic maps is awesome! I wish it was faster, it's currently too slow for car navigation(for me)! I've been using OsmAnd, the UI isn't the greatest but it's fast enough for car navigation and is prob the most useable osm based map apps available
