Art Authority is a personal museum that's open all day. The information is organized into eight categories: Early, Renaissance, Baroque, Romanticism, Impressionism, Modern, Contemporary, and American.

With every painting you admire, the app lists its title, year, materials, size, and location. Unfortunately, there isn't more information about the pieces than that. However, the works of art are all in high resolution so you can see every brushstroke when you zoom in. This app isn't worth the purchase if you just want to casually look at some art, but if you're taking a class or happen to be a serious art aficionado, it's worth the purchase.
