Waste of money The app was badly designed. It's hard to find the information you want because you can't search for it. You must either try to find it in a big list of locations or by using the map, which is terrible - the developers should have used Google Maps for this function. Also, there are missing points of interest and sometimes the pictures representing the locations don't load. I tried to use this app while I was visiting the site and it was of very little use. Don't rely on this app for your visit.
Horrible app Barely works. There is no GPS map. Very slow and freezes.
I recommend but: The map needs to be improved, Google maps has better details than this one. Explanation are good. Can't pause the tts, if stop it starts from the beginning. Difficult unfortunately to browse and find the current location because they are a lot, maybe add a search field? When opening the map from current place button it doesn't show the pins.
Easy tour Don't waste money on tourist panflets. This gave us all the info we needed. Awesome.
