The “PrättiApp” is a mixed reality app for smartphones that allows families to get to know the cultural treasures of the Prättigau Alpine region in a playful way. The app is an educational game that can be played locally, i.e. in the various communities of the Grisons mountain region. Together with their parents, the children learn up close about the lively Prättigau culture – local experiences are enhanced by digitally retrievable information. The PrättiApp is thus the region’s first interactive and up-to-date educational tourism tool. However, the focus is not on the digital, the mobile phone serves as an aid to enhance the families’ experience in the region. In addition to the educational component, the PrättiApp is also a platform for local artists and cultural entrepreneurs to promote their work in a child-friendly way.
