CityRiddler

With the CityRiddler App, you explore the city with the eyes of a local. You tell the app what you like, how much time you have, and where you want to start and end. The CityRiddler Engine will work its magic to create a unique and unforgettable experience for you and your friends!

Behind CityRiddler stands a young startup from Vienna, who combines their passion for travelling with their love for riddles.
