Scan a room with your iPhone or iPad and get a true-scale floor plan in minutes. vPlan AR uses LiDAR and Apple's RoomPlan to measure walls, doors and windows as you walk, typically within 1–2 cm (under an inch) per room dimension. Square footage, ceiling heights, a 3D model and professional exports come from the same scan. Built for insurance adjusters, home inspectors, contractors, realtors, architects and designers who need accurate measurements on site, fast. SCAN ROOMS AND WHOLE HOUSES • Walk each room and watch walls, doors, windows and openings appear on a live 3D model. • Scan every floor in one session and the levels line up for multi-level plans and 3D. • Plans open square to the page, with north from the iPhone compass. • Cabinets, appliances, fixtures, furniture and stairs found in the scan go on the plan. • Room photos while you scan (Pro and Business), pinned where you stood, facing the way you looked. Faces in automatic photos are blurred. ACCURATE FLOOR PLANS AND SQUARE FOOTAGE • Room-by-room area, perimeter and ceiling height, and the total square footage. • ANSI Z765-style square-footage (GLA) report for appraisals and listings (Pro and Business). • Door and window sizes, room names and dimensions on the plan. EDIT ON IPHONE AND IPAD • Move and resize walls, add doors (swing, double, sliding, pocket, bifold and garage), windows and openings. • Place furniture and fixtures that snap to walls, stairs sized for the level above, and floor openings. • Floor, wall, ceiling and baseboard finishes, shown in 3D. • Pin photos on the plan and view 360° photos. 3D MODEL AND AR • Every plan in 3D, with furniture and finishes. • View in AR puts the 3D model around you at full size. EXPORT FOR WORK • True-scale PDF floor plans: Letter or A4 on Free, multi-level plan sets on Pro with a 3D cover, room schedules and large sheet sizes. • DXF for AutoCAD and other CAD software, at real size with editable dimensions (Pro). • 3D models as GLB, USDZ and OBJ (Pro). • Excel and CSV schedules and room-by-room measurement sheets for estimating (Pro). • IFC (BIM) for Revit and ArchiCAD, and XML floor plan data (Business).
