MagicPlan creates inside maps (floor plans), measuring your rooms by pictures at key locations. Easily add objects, annotations, and attributes to create an inside floor plan. Do each room individually and put them together like a puzzle as you go.

You can then share your map for free with any MagicPlan user, or pay to get it as a separate file formats or to publish an interactive map on the web. All you need is a smart phone or tablet and download the app for free. This is different from a floor plan drawing application because there’s:

No need to measure
No need to draw
No need to move furniture
No need for expertise.

Some of the paid features include:

Certain objects are locked
PDF + JPG + Interactive Web Site + DXF + CVS
Commercial usage.
