Scan a whole wall, not one spot. MetalHunt maps the studs, finds the spacing and shows the safe gaps between them. Offline, no ads. MetalHunt scans a whole wall, not one spot. It maps the studs, works out the spacing and marks the safe gaps between them before you drill. Calibrate first. Swing the phone in a figure eight until the app confirms it — until then a reading can show a find on an empty table. NEW IN 2.0 - Wall Map. Scan a wall in a grid and get a heat map of the whole surface instead of one live number. Save a map for every wall and export it as an image. Wall Map is in beta: rows are divided by time rather than distance, so the map is faithful only if you sweep at an even pace. - PDF report. Turn any scan into a document you can hand to a client or keep with your renovation notes. - EMF Inspector. Measure the field around a microwave, router, fridge or bed, and read each result next to the typical published range for that appliance. - Lab Mode. Five guided experiments with the raw magnetometer signal. - Stud Assist. Classifies the shape of a signal so you can tell a stud edge from a pipe. - Sonar audio feedback, peak hold, a home screen widget, Shortcuts and quick actions. WHAT IT FINDS - Iron studs and steel framing before drilling - Steel pipes and rebar in walls, floors and concrete - Nails, screws, bolts and hidden hardware - Magnets and steel tools - Magnetic fields from motors, microwaves and transformers WHAT IT CANNOT FIND The iPhone magnetometer reacts to ferromagnetic materials only: iron, steel and nickel. It cannot find gold, silver, copper, aluminium or brass, and no app on any phone can. It measures magnetic field strength, not depth, and it is not a medical or safety device. Always confirm with a proper stud finder before you drill. PRIVACY No accounts. No ads. No analytics. Nothing leaves your phone and the app works fully offline. Built in Litovel, Czechia.
