Organic Maps is a privacy-focused offline maps and GPS navigation app for hiking, cycling, walking, and driving. It is a community open-source project published by Organic Maps OÜ in Tallinn, Estonia. Map data comes primarily from OpenStreetMap as region packages you download once and then use without a network connection.
It exists as a donation-funded alternative to always-online commercial maps. The official site states no ads, no tracking, and no data collection for the core experience. Install channels include the major app stores, F-Droid, and GitHub releases.
The concrete differentiator is that offline-first OSM client with turn-by-turn voice guidance, outdoor layers (trails, contours, elevation), and Apache-2.0 source. Public transport routing is still partial, not a completed peer to Google Maps transit.
