Walk through your home with your iPhone. HouseScan captures the walls, doors and windows by itself and draws the floor plan. The PDF is free, no credit card. The CAD file (DXF) is $5 for the home.
It needs an iPhone Pro (12 Pro or newer) or an iPad Pro, which have the LiDAR scanner. Open this page on that iPhone and tap the button: Apple's TestFlight installs HouseScan in two taps.
