Jitsuhiro - True Floor Area

True area, not listed size

Import a floor plan and calculate the true net usable area after subtracting columns and structural walls. Visualize how the listed "6.0 jo" room actually measures up once pillars eat into the space.

Features

Import floor plans from PDF, photo library, or camera (auto-corrects perspective distortion)
Set real-world scale by tapping two points on a dimension line
Auto-detect pillar candidates, confirm/adjust, then calculate net area and jo difference
Place furniture on the scaled plan to verify clearance and traffic flow before moving in
Export result cards and layout diagrams as images to share
