Organic Maps is a free, open-source, privacy-by-design navigation app built on OpenStreetMap, with no ads, no tracking and no accounts. Registered in Estonia and community-funded, it is fast, lightweight and works completely offline — a favourite for travel, hiking and cycling.
If your priority is a clean, no-nonsense map that respects you entirely, Organic Maps is one of the purest European alternatives to Google Maps you can install.
