SecretGuide book classes

SecretGuide turns your smartphone into a personal audio city guide—flexible, stress-free and full of local stories. Whether it's a Melatenfriedhof in Cologne, Beethovenhaus in Bonn or Kontorhäuser in Hamburg — every tour tells stories authentically, personally and without pre-arranged group times. City guides design the tour themselves, record it on site and share their passion for history — without AI, just real knowledge and real voices.
