Poor User Experience
This app is very frustrating to use. First, you must follow the path displayed on your screen or you cannot see the images or listen to the commentary. Second, even if you walk to the correct place, sometimes, the phone location isn’t precise so the app tells you to walk back to the place you just left. You end up in the back-and-forth walking experience when you simply want to see the art and listen to the commentary. I won’t say this app ruined my experience, but I certainly wouldn’t substitute it for an audio guide or tour experience. Both of those will be a far better experience than this frustrating app.
