My wife saw advertisements for this tour so we decided to walk around to some of the stops and check it out. The visuals are stunning and the tour itself is extremely entertaining and enlightening. I have honestly never seen a tour of this kind so it really blew me away.
There were a few times when we were taking this tour that we ran into volunteers (or people who work for the company who created this tour) asking us if we had any questions about using the app on our phone or if we had any questions about the tour itself. I thought this was a great touch.
The one small complaint I had was the amount of time it took to download the audio at each stop within the app. There has to be a way to compress the audio file to speed up the download time.
