About 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.
