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 or advertising. 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.
