In the Niki Your TravelBuddy App you choose the city you want to walk and read the information about the available tour(s). On the preview you see the route of the tour. After starting the tour, you will be navigated to the nearest starting point. Then you will be neatly guided from point to point via GPS and informed about the sights. If the GPS refuses or is inaccurate, which unfortunately happens in the center of a city, you can always clearly see on the screen where you are and where you have to go.
