RoomSketcher

RoomSketcher produces accurate editable floor plans, published with industry provision, a downloadable application and monthly or annual billing including a free tier.

The professional output requirement is what distinguishes this from general drawing software, and it matters most in the industries that buy it.

An estate agent's floor plan is a marketing document that must be accurate, because a buyer relies on it and a materially wrong measurement is a legal problem rather than an error. It must also look consistent with every other plan the agency produces, since a portfolio of listings with inconsistent plans looks amateur.

That combination, measured accuracy plus consistent presentation, is what general drawing tools do not provide. A plan drawn freehand looks fine and cannot be relied upon, and one drawn in a CAD package is accurate and looks like an engineering drawing rather than a marketing asset.

Editability is the other requirement that sounds minor and is not. Properties change, listings are re-photographed, and a plan that must be redrawn from nothing each time will not be updated, so listings carry plans showing a layout that no longer exists.

The free tier makes this accessible to homeowners and occasional users planning a renovation, which is a genuinely different audience from the professional one and is served by the same tool because the underlying task is identical.

Pricing is published with monthly and annual billing, a free tier at $0 and $38 covering one user with the RoomSketcher App.
