This app delivers a good overview of art collected into its major periods. The interface is easy to use. I had expected more and better functionality given its significantly higher than average price. Each piece of art is downloaded from the Internet each time as required. I would have liked to have seen the apps selected "overview" pieces included automatically. This also means that things can be slow: I was looking for a particular Rembrandt painting. It took four minutes for the large number of Rembrandt thumbnail sketches to download so I could find the one I wanted. There is no index of painting names. Thus I cannot use this app to look up a specific painting referenced in a book I am reading. I might want to compare how different artists handle the portrayal of David and Goliath but there is no way to do so. Having found a painting of interest, there is no "tell me more" function. Instead, there seems to be of a link to Wikipedia about the art movement of that time period or an app-specific link to information about the artist. In short, the app offers some value relative to reading Wikipedia or googling an artists name but not as much as it should.
