The Blauzahn App for augmented storytelling is taking you through a new kind of audio walks. Choose from an increasing number of stories and tours, plug in your headphones and let you guide through a new storytelling experience in which you are part of the story and even can interact with other people within the same story. The App is a "player" for those stories. They are downloaded from the Blauzahn server and may be owned by various organizations. Some are free, for some you may need to pay. Be aware that almost all stories are fixed to a certain location. Only download the App if you are close to one of those locations. For more details see www.blauzahn.ch . Continued use of GPS running in the background can dramatically decrease battery life.
