Can you draw a perfect circle? It sounds simple — but scoring above 90% is brutally hard.
Perfect Circle uses real computational geometry to analyze every curve, wobble, and gap in your drawing. You'll get an instant perfection score from 0-100% backed by scientific least-squares circle fitting. See exactly where your circle falls short: radial wobble, incomplete arc, poor closure, or inconsistent curvature.
