DuoSketch

Why DuoSketch is different

DuoSketch is designed around the fold instead of simply stretching a phone interface across a larger screen.

Keep a reference photo or lesson visible beside your canvas
Draw with Apple Pencil or your finger
Use pencils, technical pencils, pens, fountain pens, markers, highlighters, brushes, and erasers
Organize your work with real drawing layers
Move the professional tool palette to the left or right side
Fold the device and continue with a focused single-screen drawing experience
Open it again and instantly return to the reference-and-canvas workspace

A complete drawing studio

Everything needed for everyday drawing is included:

Blank canvases
Reference gallery
Zoom and pan
Undo and redo
Layer visibility, opacity, ordering, and deletion
White, off-white, black, grid, and dotted backgrounds
PNG, JPEG, transparent PNG, Files, Photos, and Share Sheet export

Learn step by step

Follow original lessons designed for drawing on Duo. The reference or lesson step stays on one side. Your drawing remains on the other. Move through the lesson without losing your previous strokes.

Learn the shape. Build the lines. Finish the drawing.

When you want to convert a photo into clean line art, Photo Trace processes the image directly on your device using an on-device image pipeline.
