tl;dr: Organic Maps is a free, open-source, privacy-focused offline maps and GPS app built on OpenStreetMap data, targeting hikers, cyclists, and drivers with features like turn-by-turn navigation, contour lines, and bookmark import/export. It contains no ads, trackers, or data collection, works entirely offline to save battery and data, and is forked from the original MapsWithMe/Maps.Me team. The project hit 6M installs in December 2025 and is funded by donations and institutional grants.
