Built for both screens

Unfold for the big picture. Your floor plan and furniture list sit next to each other, so you can drag a Queen bed into the bedroom, then measure the gap to the wall.
Fold for a quick check. The full app works on the outer screen too, so you can measure a sofa in the store aisle or on moving day.
Every pose, no black borders. The layout adapts as you open, close, and rotate iPhone Duo, and every piece stays at true scale.

How it works

Upload a photo or screenshot of your floor plan, or draw one.
Calibrate the scale against one known measurement, like a door or a listed room width.
Drag in furniture at its real size and check the walkways before you move a thing.

Napkin Plan also runs on iPhone, iPad, and in any web browser.

Free to start, with one plan included. No credit card.
