Guided trips bring back memories from school days and the most interesting historic and natural sites visited. Not all places we would like to visit allow the use of a guide. The magic of a virtual guide comes to the rescue. Modern technology not only allows you to see photos and read descriptions, but also allows you to listen to audio files and indicate the optimal route. A walk with a mobile guide with navigation function and audio playback is a new quality in interpersonal communication, tourism and business. The application also has a positive impact on facility management by collecting data about visitors and their opinions on individual elements of the entire facility.
