OpenStreetMap

OpenStreetMap is the open, community-built map that nearly every private navigation app relies on, including the others on this list. Anyone can browse the world map at openstreetmap.org without an account and anyone can help improve it so the data belongs to the public rather than to a single advertising company. Because it is a map project rather than a turn-by-turn app, it does not do voice navigation on its own. Think of it as the foundation: pair the website with an offline app like Organic Maps or OsmAnd for actual routing. There are no ads, no tracking, and no login just to see where you are going.
