Very handy Great offline maps and good content about the various attractions. The design is beautiful. Only thing missing is user reviews otherwise this would beat TripAdvisor.
Excellent Really handy during a visit to the city
Offline map makes it very good No problems. Off line map made it easy to use when on travel. Best one for Petersburg, even though Coil devs Petersburg is maybe more detailed but without map.
One audio guide for all the best museums of Saint-Petersburg Russia and environs
