Pedestrian routing with YOURS
The YOURS routing service not only supports motorcar and cycle routing, but also pedestrian ("foot") routing. This option should be available in the App too, currently the pedestrian option is missing (see attached screenshots).
From the API documentation on the official Wiki page (https://wiki.openstreetmap.org/wiki/YOURS): "v = the type of transport, possible options are: motorcar, bicycle or foot. Default is: motorcar."
