Is there an app for identifying artists signatures?

Yes, there is an app for identifying artists' signatures. Called Smartify, the app is available for both iOS and Android devices. The app can be helpful in determining who created a work based on signatures. However, reviews suggest that it does have limits. For the app to properly identify a painting or other piece of art, the artist must be included in its database, and because there is a lot of art in the world, not all artists can be found in the app.

Note that not all names you find on a given work of art may belong to an artist. Previous owners may have written their names on the back of the painting you’re examining, for example. If you’re trying to identify an artist’s signature, you should work with an art authenticator or other industry specialist who is familiar with authentications in the era or style of your artwork.
