This is not an audio guide It has a few paintings with an annoying voice talking about them. After that you have to pay to see any more paintings, so it's just a money making program, and a waste of money at that.
Not a free audio guide Only 10 items are free to listen to. It's actually cheaper to get the €5 audio guide at the museum than the in app purchases for the rest of the items.
Pay per paint.. And crash Crashes easly and almost no content.
