BRouter does only the plain route-calculation and does not display a map or the calculated route on it's own and therefore works only together with a Map Application. There are two different methods for the interfacing between BRouter and the Map application: BRouter offers a service interface that is called by the map application without a need to start the BRouter-App. This way, BRouter is a routing service very much like an online routing service, including dynamic recalculations if you get off the track. The other mode of operation is to start the BRouter-App and use waypoints from the map application's waypoint database to define your route. The calculated route is then written as a GPX file (including the elevation profile) to the map-application's tracks directory.

Some popular map apps support both the service interface and the interface via the wayoint database in their current versions available on Google Play.

The service interface uses a timeout of 60s, limiting it's use to distances of about 50km, but using the BRouter App you are able to calculate much longer distances. But even long-distance tracks can be followed via the service interface (including dynamic recalculations). This is done by pre-calculating a route for your destination once using the BRouter App and assigning it to a routing mode via the "Server-Mode" Button. This feature is called "timeout-free recalculations".

The route calculation, no matter if via the service interface or via the BRouter App, also considers nogo areas that can be defined as waypoints with a special naming convention (e.g. "nogo200" for 200m radius). This way it is possible to account for actual obstacles, but this feature can also be used to enforce personal preferences.

BRouter contains a download manager that assists downloading the required routing data files.The download manager is called on the
