CoMaps is a community-led, free and open source offline maps and navigation app for Android, iOS, macOS and Linux, built on OpenStreetMap data and aimed at people who want turn-by-turn navigation without tracking, ads or data collection.

What it is

CoMaps is a C++ navigation application licensed under the Apache License 2.0. It is a fork of Organic Maps, which was itself originally based on Maps.ME, and it positions itself as a community-led project governed for transparency, privacy and not-for-profit values rather than commercial return. The application ships on Android, iOS, macOS and Linux, and it is distributed through the App Store and Google Play as well as built from source.

The concrete problem it solves is navigation that depends on a live connection and on the data collection practices of commercial map providers. CoMaps works offline first: maps are downloaded ahead of time and the app then routes without a network, which matters on hiking trails, cycleways and rural roads where coverage is absent. Its map data comes from OpenStreetMap and includes detail the README explicitly notes is not available with Google Maps, so the replacement here is a proprietary, always-online navigation app rather than an additional layer on top of one.

Key capabilities

• Offline navigation with voice announcements for walking, cycling and driving.
• Downloadable detailed maps covering outdoor information such as hiking trails, campsites, water sources, peaks and contour lines.
• Export and import of bookmarks and tracks in the KML, KMZ and GPX formats.
• Offline Wikipedia articles, a subway transit layer and subway directions.
• Track recording and one-tap bookmarking of favourite places.
• A basic built-in editor for improving OpenStreetMap data directly from the app.
• Android Auto and CarPlay support, alongside a dark mode for night use.

Who uses it and how

• Hikers, cyclists and drivers who need routing in areas without mobile data, using pre-downloaded maps and the outdoor mode with highlighted trails and water sources.
• Privacy-conscious Android users, for whom the app has been reviewed by Exodus Privacy and distributed with published signing certificate fingerprints verifiable through apksigner and AppVerifier.
• Contributors who build from source following docs/INSTALL.md, work to the guide in docs/CONTRIBUTING.md, and coordinate through a dedicated Zulip chat for team messaging.
• Supporters funding development through OpenCollective or Liberapay, with financial information kept open and transparent at the project's Open Collective.
• In-car users relying on Android Auto and CarPlay integration for driving navigation.

Getting started

Install from the App Store or Google Play for everyday use, or build from source by following the instructions in docs/INSTALL.md.

How it compares

Within this registry it sits directly in the lineage of Organic Maps, the project it forks, and Maps.ME, the application that lineage originally came from. Against Google Maps, the contrast the README draws is the offline map detail and the absence of tracking, ads and data collection, with OpenStreetMap as the underlying data source rather than a proprietary dataset.

When to use it — and when not to

Choose CoMaps if offline navigation, OpenStreetMap data and verifiable privacy matter more than the polish of a large commercial provider, and if building from source per docs/INSTALL.md or installing from a store is acceptable. Do not pick it expecting a hosted service or a container deployment: the facts describe a client application with store distribution and a source build, and nothing more. The README is a highlights and funding document rather than a detailed technical specification, the topic list is empty, and the issue tracker lives on Codeberg rather than GitHub, so anyone evaluating it for a workflow should expect to read the repository documentation rather than the landing page.
