Artist Tools

Artist Tools gives you the essential reference tools that classical 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. ━━━━━━━━━━━━━━━━━━━━ 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. ━━━━━━━━━━━━━━━━━━━━ BUILT FOR ARTISTS • Works completely offline — no internet required • Organize guides in layers — toggle visibility, delete, rearrange • Auto-saves your work as you go • Export finished studies to your gallery • Dark interface that won't strain your eyes in the studio • Clean, minimal design that stays out of your way ━━━━━━━━━━━━━━━━━━━━ WHO IS THIS FOR? • Figure drawing students learning proportion and anatomy • Portrait artists checking alignments and value structures • Plein air painters simplifying complex scenes • Atelier students practicing classical techniques • Anyone who wants to improve their observational skills ━━━━━━━━━━━━━━━━━━━━ Artist Tools replaces the physical tools you'd find in any traditional atelier: the plumb line, the measuring stick, the black mirror, and the squinted eye. Study any reference with precision. See values clearly. Draw with confidence.
