Google's latest app (for iOS & Android) allows you to view and learn about works of art. You can search by historical movements or artists, or by medium, e.g. ink or watercolour.
You can search by place if you want to see the art that's available near your location, and everything you view on the app can be saved for viewing later.
If you have Google Cardboard, you can use the app to take virtual tours, and Google say they are working on image recognition functionality that will let you take a photo of a painting and the app will give you information about it.
