Organic Maps is a free, open-source, donation-based and privacy-focused Android and iOS offline maps app for travelers, tourists, drivers, hikers, and cyclists based on crowd-sourced OpenStreetMap data.
Organic Maps is a fork of MAPS.ME (MapsWithMe). MAPS.ME was created by me and my friends in 2011 and open-sourced in 2015 under Apache 2.0 license. In Organic Maps all unnecessary “features” like tracking and statistics collection were removed. The main focus is on speed,
stability and up-to-date OpenStreetMap maps data, to make it the most secure, fastest and battery-efficient offline maps app.
