Millimeter paper app for floor plan drawing

Hello,

does anyone of you know an app where you can draw on graph paper? Preferably with a tool for straight lines, etc...

I would first like to draw my floor plans on "paper" before transferring them to the well-known programs where I get all kinds of views.

And why not on real paper? I "hate" real paper^^ and I'm too messy for a pile of real paper

SweetHome draws on graph paper. If you do it on the computer anyway, why do it twice?

You have to scribble sketches freehand, otherwise it won't work

Because in some planning thread it was said that you should start on millimeter paper before working with other planning tools and 3D views...

I also work almost paperless in the office... I just find handwriting/drawing messy and untidy

But "graph paper" was meant synonymously with "analog drawing," that is, on the medium paper. This suggestion would be perverted to the greatest extent if you then resorted to a "graph paper app." The fact that orange grid lines are placed under the pixels was not meant by the suggestion. Rather, the message is: "dare to scribble" or "practice imperfectly in reality before switching to virtually perfect."
