Tap to build a shape

Tap to drop points and grow your outline one side at a time. Leave it as an open path or close it into a solid shape — your call.

Exact side lengths

Every edge is editable. Type a precise length or nudge it up and down — right down to the millimetre.

Precise corner angles

Drag a corner freely, or dial in an exact angle with handy 30°, 45°, 60°, 90°, 120° and 135° presets.

Area & perimeter, live

Side count, area and perimeter update the instant you move anything. No calculator, no guesswork.

Metric or imperial

Work in mm, cm, m, inches or feet. Switch anytime — the shape stays put, only the numbers change.

Snap, save & reopen

Optional grid, length and angle snapping keep everything true. Save sketches to your library and reopen them whenever you like.
