CoMaps is a free, community-led offline navigation app for hiking, biking, driving, and city transit. It is a nonprofit fork of Organic Maps built on OpenStreetMap data, with maps that download to the device so search, routing, and guidance keep working over GPS alone with no mobile signal. The project states it identifies nobody, tracks nobody, and collects no data, and it publishes its code openly under Apache-2.0.[1][2]
Quick verdict
CoMaps suits hikers, cyclists, and privacy-minded drivers who want navigation that keeps working with no mobile signal. It ships downloadable OpenStreetMap data with GPS-only search, routing, and voice guidance, plus an outdoor mode for trails, campsites, and contours. The tradeoff is live-service breadth: real-time traffic depth, business reviews, and transit coverage trail networked incumbents, and public-transport layers are still growing city by city. Choose CoMaps if offline reliability and no data collection matter most; keep a live-data app alongside if you depend on real-time traffic or transit.[1][2]
Key features
Offline GPS-only routing Regional maps download to the device, so search, route calculation, and guidance work entirely offline over GPS with no mobile data or account.[1]
Turn-by-turn voice guidance Spoken turn-by-turn directions continue without a signal, which matters on remote roads and trails where live-data apps lose coverage.[1]
Hike, bike, drive, and transit modes One app covers hiking, cycling, driving, and public transport, including waypoints on remote trails; transit layers are available in a growing list of cities.[1][2]
Outdoor mode with contours An outdoor mode highlights hiking trails, campsites, and water sources with contour lines for terrain reading away from the road network.[1]
Offline Wikipedia for nearby places Offline guides with Wikipedia articles describe nearby points of interest, so place context travels with the downloaded maps.[1][2]
OpenStreetMap data with built-in editor All map data comes from OpenStreetMap, and a built-in basic editor lets users add or correct details and contribute them back to the shared map.[1]
Bookmark and track interchange Bookmarks, tracks, and routes import and export in KML and GPX, so existing collections and recorded trips move in and out freely.[1]
Car and transit integrations Android Auto and Apple CarPlay support plus public-transport maps extend the offline core to the dashboard and city commuting.[1]
Who will love it
Off-grid hikers and bikepackers People who navigate beyond mobile coverage get the most: downloadable terrain, trails, campsites, contours, and GPS-only guidance match multi-day routes.[1][2]
Privacy-minded everyday drivers Drivers who want guidance without accounts, ads, or location tracking get turn-by-turn navigation from a project that states it collects no data.[1]
Travelers without reliable data Anyone roaming, on limited plans, or crossing dead zones keeps search, routing, and place guides working from on-device maps.[1][2]
Who should avoid it
Thinner live services Because everything runs from downloaded maps, live traffic conditions and real-time disruption alerts are limited to what the on-device data holds, unlike networked incumbents that stream current conditions and reviews.[1][2]
Young fork, still expanding CoMaps is a young community fork that asks testers for feedback on beta builds, and its public-transport layers are still growing city by city rather than complete.[1]
Mobile and car first The supported surface is Android and iOS apps plus Android Auto and CarPlay; there is no evidenced desktop planning or web companion in the project's own materials.[1]
Platforms and data
Android and iOS distribution Stable builds ship through Google Play, F-Droid, and the App Store, with beta builds alongside them, and the dashboard story is covered by Android Auto and Apple CarPlay.[1]
Open data and open code Map data is OpenStreetMap with downloadable regional packs, tracks interchange in KML and GPX, and the full codebase is Apache-2.0 on Codeberg with a GitHub mirror.[1][2]
Questions worth asking
What is the best CoMaps alternative for non-technical users?
CoMaps itself is built for non-technical users: a polished interface, downloadable regional maps, and GPS-only routing with voice guidance need no technical setup. If you want the same offline simplicity with a longer release history, consider Organic Maps, the project CoMaps forked from; stay with CoMaps if nonprofit governance and no data collection matter more to you.[1][2]
Is CoMaps really no-code?
Yes for everyday use: CoMaps is a consumer app with a visual interface, and its built-in editor lets anyone add or fix map details without writing code. Code, translation, and testing contributions exist but are optional; using the app for navigation requires none of them.[1]
How much does CoMaps cost per month?
CoMaps costs nothing per month: the app is free with no account, no ads, and no paid plans, and funding comes from voluntary donations through Open Collective, Liberapay, Ko-fi, and SEPA transfer. Donations support development but unlock nothing extra, so the monthly cost for users is zero as checked in October 2026.[1][2]
Can you self-host CoMaps?
Self-hosting does not apply to CoMaps in the server sense: it is an on-device app, not a hosted service, so there is nothing to deploy. Maps and guides download to the phone and routing happens locally over GPS; the project's Codeberg repository is public for anyone who wants to inspect or build the open-source code under Apache-2.0.[1][2]
