DepthMap: Room Sketchpad

DepthMap treats measurements like a real architect's sketchbook: warm paper surfaces, fine violet grid lines, and crisp ink-purple geometry. Walk a room with a tape measure, type each wall length into the wizard, and watch the app ink the plan onto the canvas in real time.

DepthMap is offline-first. No accounts, no servers, no analytics. Rooms and plans live only on your device.
