Chain segments, capture dimensions and save measurements with Expanded Toolkit. • Ruler: a full-height, calibrated on-screen ruler in metric or imperial units, with a drag handle that stays clear of the controls. • Feet & Inches: calculate fractions, convert metric lengths, add or subtract dimensions, multiply, divide and find equal spacing. • Height: mark a base and top to estimate vertical height. • Area: outline a flat surface to estimate its area. • Floor Plan: enter wall lengths or mark floor corners, then save and share a plan. • Room Layout: scan a room with LiDAR on a supported iPhone. Export USDZ, OBJ, SVG and JSON files to a computer for compatible 3D, drawing and rendering software.

Room scanning requires a LiDAR-equipped iPhone. Camera Level displays virtual guides; it does not project a laser. Magnetic Field is not a dependable wire or stud detector. Photo angles can be affected by perspective. Check critical measurements with appropriate physical tools. No account and no in-app ads. Photos, scans and saved measurements stay on your device unless you choose to share them. Camera access supports camera and AR tools; optional location access supports true north. Purchases and restores require internet access. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
