Organic Maps and CoMaps are free offline map apps for Android and iPhone. Both use OpenStreetMap data and let you search places and navigate with downloaded maps. Their features overlap, but each project's current releases offer different reasons to consider it.

Organic Maps for transport routes and several stops

Organic Maps added public transport routing by subway, light rail, bus and tram in June 2026. Its September release added an option to optimize the order of route stops. These documented tools make it worth considering for city travel or a journey with several destinations. Check the route and map coverage for your area before travelling.

CoMaps for outdoor route controls

CoMaps documents route options for avoiding paved roads, unpaved roads and steps. Its outdoor mode highlights trails, campsites and water sources. On Android, it also provides automatic backups for favourites and tracks. Consider these tools when route preferences or keeping a copy of saved places matter to you.

Prepare for offline use

Download the regions you need while connected and allow enough phone storage. Map updates, shared data and external links can still need internet access. Both projects evolve, so check the current release and device requirements on their app pages.

Choose Organic Maps when its public transport and multi-stop tools fit your trip. Choose CoMaps when its outdoor controls and Android favourites backup fit your workflow. These choices follow publisher documentation; route coverage depends on the area and map data.
