Measure a room once. Keep a plan you can actually use. Planmark turns a LiDAR-equipped iPhone Pro or iPad Pro into a guided room-measurement workflow for moving, furniture planning, renovation and field documentation. Capture walls, doors and windows, review the dimensions, and keep both a clean 2D floor plan and the original 3D room scan. SEE THE RESULT BEFORE YOU BUY Open the included sample project to inspect the 2D plan, 3D preview, wall measurements and PDF workflow. New room scanning unlocks through a one-time Home or Pro purchase. SCAN AND UNDERSTAND YOUR SPACE • Guided LiDAR room capture • Automatic room outline with walls, doors and windows • 2D floor plan with measurements for every captured wall • Original 3D room scan you can rotate and inspect • Room area, perimeter and door/window count • Metric and imperial units • Saved projects for later review HOME: A CLEAN PLAN FOR YOUR OWN SPACE Home is designed for moving, checking furniture fit and preparing a renovation. • Room scanning and saved projects • Clean personal PDF without a watermark • Wall lengths, area and perimeter in one shareable document PRO: CLIENT-READY FIELD HANDOFF Pro turns a measured room into a structured package for designers, remodelers, contractors and property professionals. • Client-ready PDF report package • Client, site, prepared-by and revision details • Measurement review table and door/window schedule • Takeoff summary CSV • SVG vector export and DXF beta export • Multi-room site package for a single handoff SIMPLE WORKFLOW 1. Scan the room slowly with walls, corners and floor boundaries visible. 2. Review the 2D plan and original 3D scan. 3. Check important wall measurements. 4. Save a personal PDF or prepare a client package. DEVICE REQUIREMENT New room scanning requires a LiDAR-equipped iPhone Pro or iPad Pro that supports Apple RoomPlan. On devices without LiDAR, you can explore the sample result but cannot capture a new room or purchase a scanning unlock. Measurements depend on the environment and sensor capture. Verify critical dimensions before construction, fabrication or ordering materials.
