PLEASE CHECK BEFORE PURCHASING New room scanning requires LiDAR. On iPhone Duo and other devices without LiDAR, buying Home or Pro or restoring a purchase will NOT enable new room scanning. Do not purchase to scan new rooms on these devices. You can edit existing rooms or import .planmark files captured on a LiDAR device. Export features depend on your Home or Pro access. Measure a room once. Keep a plan you can actually use. Planmark turns a LiDAR-equipped iPhone 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. On a compatible LiDAR-equipped device, a one-time Home or Pro purchase unlocks new room scanning. Purchasing does not enable scanning on devices without LiDAR. 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 that supports Apple RoomPlan. iPhone Duo and other devices without LiDAR cannot scan new rooms, whether or not you have purchased Home or Pro. Without LiDAR, you can explore the sample, open and edit existing rooms transferred through a device-data restore, or import .planmark files. Export features depend on your Home or Pro access. If you have no existing rooms or files to import, purchasing will not let you capture a new room and create its plan on this device. Measurements depend on the environment and sensor capture. Verify critical dimensions before construction, fabrication or ordering materials.
