Beauty can be found in unexpected places. Calefax will take you on a musical tour around your favorite city. Let the music be your guide and experience a magical trip full of secret meetings, personal memories and unexpected moments. The Hidden Gems app offers GPS-triggered audio tours. To use the app you’ll need to turn on Location Services / GPS on your smartphone and plug in your headphones. Tours are now available in five cities in The Netherlands: Amsterdam, Rotterdam, Utrecht, Nijmegen and Groningen. Dutch and English spoken versions are available. More tours in different countries will be added in the near future! At the end of each tour, an actual treasure is hidden. Can you find it? There will be a nice surprise waiting for you. Will you join our treasure hunt?
