I built this art pricing app for myself and it actually works!

First, I built a database of thousands of artworks across multiple marketplaces.  Then, as a fine art appraiser, I extracted the curvilinear relationship between size and price. and built the app to access that information about the current market every time it is opened.  If you know a valid price for one of your works, you can instantly price all other canvas sizes -- even custom dimensions.

Try it for yourself...

Works for any style of art from abstract to hyperrealism.

And it's Free... Forever.
