Don’t expect much
I’ve never encountered such a worthless app. First of all it was difficult to register the book and pair them. Took several attempts. Scanning the QR did not work. There is no menu once you’re in the app and the camera doesn’t pick up the arrows in the book or the photos of the artworks. I was able to view one video (Caravaggio) but it’s only 46 seconds long and provides zero guidance. The book is good but was really looking forward to using the app for supplemental guidance. The app is useless.
