Overview

Organic Maps is a privacy-first offline maps and GPS application for Android and iOS built around OpenStreetMap data. It provides maps, walking/cycling/driving navigation, hiking trails, public transport, offline search, and bookmark/track import and export while the README states no ads, no tracking, no data collection, and no registration. The source code is Apache-2.0 licensed, while map binary data uses a separate license.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Store regional maps on the device and use search, routing, and navigation offline

The README lists detailed offline maps, offline search, turn-by-turn walking, cycling, and car navigation with voice guidance, subway/public transport routes, and contour and elevation information.

Trails, walking paths, peaks, and slopes target hikers, cyclists, and travelers using community-maintained OpenStreetMap data.

Handle KML/KMZ/GPX/GeoJSON tracks without an ad or tracking business model

Bookmarks and tracks can be imported and exported as KML, KMZ, GPX, and GeoJSON. The README explicitly states no ads, no tracking, no data collection, no phoning home, and no required registration.

Repository topics include android, ios, openstreetmap, offline-maps, privacy, and routing, while the primary language is C++. OSS Tanbou can show C++ + OpenStreetMap in Built with.

For travel, hiking, and cycling where offline access and privacy matter more than cloud personalization

It fits Android and iOS users who need navigation in areas with poor coverage, roaming, or data limits, and users who want to avoid advertising and behavioral tracking.

Offline use requires downloading the regions you need ahead of time

Because the application is designed around offline maps, users should download destination or hiking-region data while connectivity is available and keep the locally stored map data updated as needed.

The Apache-2.0 source code and binary map data have different licensing requirements

The README identifies the source code as Apache-2.0, while GitHub metadata reports NOASSERTION for the repository as a whole and DATA_LICENSE.txt applies a separate license to .mwm and other binary data.

The binary data incorporates sources such as OpenStreetMap under ODbL and Wikipedia under CC BY-SA. Redistribution requires visible Organic Maps and OpenStreetMap attribution with clickable links, and white-label or rebranding use requires explicit written permission.

The latest GitHub release is an Android build, not necessarily a universal iOS/Android product version

As of September 16, 2026, GitHub's latest release is 2026.08.27-18-android and distributes an APK plus checksum. iOS is distributed through the App Store and Android also ships through Play, F-Droid, AppGallery, and other channels, so the GitHub tag should not be treated as one cross-platform version number.

Supplemental curator note

Organic Maps combines offline navigation with an explicit no-ads/no-tracking/no-registration model. The source is Apache-2.0, but map binary data has separate attribution and white-label conditions that must be reviewed for redistribution.
