Artist Tools

Your brain lies to you. Even experienced artists struggle to see proportion errors in their own work. Artist Tools gives you the classical reference tools that master artists have used for centuries - now on your phone. Import any reference image and overlay precision guides to improve your drawings, paintings, and studies. DRAWING TOOLS • Line Tool Draw straight lines at any angle. Perfect for measuring proportions and finding alignments in your reference. • Plumb Line Vertical and horizontal guides that help you check alignment. Essential for accurate figure drawing and portraiture. • Box Tool Create rectangles to frame compositions, measure proportions, or isolate areas of your reference. • Envelope Tool Draw multi-point shapes around complex forms. Trace the outer contour of any subject to understand its basic shape. • Grid Tool Overlay rule-of-thirds, golden ratio, or custom grids for composition and proportion checking. VALUE TOOLS • Value Study Analyze the tonal values in your reference. See exactly which areas are light, mid-tone, and dark. Tap individual values to highlight where they appear in the image. • Simplify Reduce your reference to fewer colors. Strip away detail to see the essential value structure - just like squinting at your subject. • Black Mirror Compress the value range to see subtle value relationships more clearly. A digital version of the traditional artist's black mirror. • Invert Flip values to check your work from a fresh perspective. • Flip Mirror your reference horizontally to spot mistakes and asymmetry.
