The museum is of great interest and the app makes it more so. I downloaded it in the cafe but didn't use it to much as I had two toddlers my grandsons with me. However l later read through the app and it enhance what I had seen. Will go back again and take it in at leisure when I'm on my own.
Might be good if it would install.
