Features

DIY Sketch turns a quick idea into an exact drawing. Tap out a shape, then set every side and corner to real-world measurements while the area, perimeter and angles keep themselves up to date. It’s built for anyone who needs a precise outline — a raised bed, a tabletop, a room, a piece of fabric, a patio — without wrestling with CAD.

Tap to build a shape

Tap to drop points and grow your outline one side at a time. Keep it as an open path or close it into a solid shape — and open it back up whenever you want to keep going.

Exact side lengths

Every edge is editable. Select a side and type a precise length, or nudge it up and down with + and −. Work right down to the millimetre.

Precise corner angles

Drag a corner freely and watch the angle update live, or open the corner and dial in an exact value. Handy 30°, 45°, 60°, 90°, 120° and 135° presets snap common angles into place, and you can flip a corner in a tap.

Area & perimeter, live

Side count, area and perimeter recompute the instant you move anything, shown right at the top. No calculator, no guesswork — the numbers are always right.

Metric or imperial

Work in millimetres, centimetres, metres, inches or feet. Switch systems whenever you like: the physical shape never moves, only the numbers on screen change.

Snap to a grid

Optional grid, length and angle snapping keep your lines straight and your corners true. Fit the whole sketch to the screen with one tap, and rotate it to any orientation.

Save & reopen

Give a sketch a name and it’s saved to your library. Reopen, tweak and re-save any drawing whenever a project comes back around.

Private by design

Everything you draw stays on your device. There are no accounts, no ads and no tracking.
