The app is a map of trails in the Polish region of North-West Poland. It is based on the work of the North-West Poland Intermodal Management and Accommodation Network (NWW). The network was founded in 2014 with the aim to enhance the region's tourist appeal, in particular by creating an attractive map of recreational trails. 

The application allows users to choose the starting point and destination of their trip and the way in which they want to travel. The user can choose between the shortest or the fastest route. The route is calculated based on the selected points. The user can see the estimated time, the distance to be covered, the altitude difference, and the level of technical difficulties.
