I am pretty much the opposite of tech-savvy, but I'm getting better. I sometimes see an art print that I find interesting, but have no information about. Sometimes I've been able to identify it by typing a description of it into my phone and doing an image search, but not always. Today I bought a print and the style looked familiar, but an image search came up with nothing helpful. So I googled "art identification app" and came up with Smartify.
A minute later I knew I'd bought a print of Francisco Goya's 'The Captivity is as Barbarous as the Crime" (1815) Very cool.
