Organic Maps
Organic Maps is a privacy-focused, community-developed, open-source navigation app. The app features no location tracking, no data collection, and no ads. Since the map data is downloaded on the device, search, routing, and navigation can operate without a cell phone signal, ideal for travel on distant hiking trails or in locations with poor connections. Organic Maps uses crowd-sourced map data from OpenStreetMap. The app is free and open-source software, with priority for community development and collaboration. Features

Integration with OpenStreetMap 
Organic Maps relies on the collaborative efforts with OpenStreetMap contributors, offering up-to-date map data contributed by the community. By integrating with OpenStreetMap, Organic Maps ensures users have access to navigation information which is used by hundreds of applications, and have the opportunity to update maps with changes in roads, addresses, businesses, landmarks, etc. History 
Organic Maps was created by the founders of Maps.Me. In 2011 MapsWithMe (later renamed to Maps.Me) was founded and in September 2015 a decision was made to open-source the app. In 2021, Alexander Borsuk and Viktor Govako forked Maps.Me to create a privacy focused, faster and simplified navigation app, and Organic Maps was born. The first public release of Organic Maps became available in the app stores in August 2021. See also
