Know when to double-check
The error margin reflects distance and what the camera locks onto. Use good light and textured surfaces, ideally from 0.5–3 m. Check critical dimensions with a physical tape before cutting or ordering.
Your measurements stay on your phone
No account is needed. Nothing you measure leaves your phone. The camera is used only while you measure, and nothing is recorded.
