The city of St.Gallen and Eastern Switzerland are internationally renowned for their textile heritage and expertise. Xponia was asked by Textilland Ostschweiz to create and develop a multi-media app with outdoor navigation for walking tours to discover unique architectural signs of the textile industry. The textile trails “St.Gallen Downtown” and “St.Gallen West” lead to magnificent buildings from the heyday of the industry and reveal in text, audio and images fascinating facts about the history, architectural style and current use of the buildings. Recommendations in the app introduce to the users, events, restaurants, accommodations, cultural sights, shopping opportunities, etc. The app is multi-lingual and available both in online and offline mode.
