Mobile Technologies, Applications and Software Design Pyeniny Audio Guide by Mateusz Slowakiewicz Pyeniny is a mobile app audio guide to Pieniny – one of the most picturesque mountain ranges in Central Europe. The fascinating stories, legends, beliefs and myths were enclosed in 25 tales told by the mysterious mountain spirit. To provide a unique experience, the app takes advantage of GPS technology which allows to lead tourists along the routes and play particular recordings precisely in places they describe. The heart of the project is the hand-drawn map which guides the travellers. The app does not use other media to do not distract the users from the natural wonders around them.
