Stud Finder: Metal Detection

Turn your iPhone into a wall scanner — find metal studs, screws, pipes and wiring before you drill. Honest µT readings, instant buzz alerts, works offline.

Find what's behind the wall before you drill.

Stud Finder turns your iPhone into a magnetic wall scanner. Sweep the phone across the wall and the gauge rises the instant metal is underneath — screws, nails, pipes, conduit and metal studs. Wood studs are found through their fasteners: follow a vertical line of hits and you've found the stud.

HOW IT WORKS Your iPhone's built-in magnetometer measures tiny changes in the magnetic field (in µT). Stud Finder zeroes itself automatically, filters out noise and shows an honest reading — never a fake "stud here" guess.

WALL SCAN MODE • Tuned for drywall: screws, nails and metal studs • Peak-hold needle shows exactly where the signal is strongest • Buzz and sound alerts the moment you cross metal (Pro)

METAL DETECTOR MODE (PRO) • Wider range for pipes, conduit, rebar and hidden metal • Continuous tone that rises as you close in • Live µT field strength for precise work

BUILT FOR REAL WALLS • Adjustable sensitivity for thick plaster or thin drywall (Pro) • Save a marker on every find and come back to it (Pro) • Warns you when a MagSafe or magnetic case skews readings • Works fully offline — no account, no tracking

HONEST BY DESIGN A phone magnetometer senses metal, not wood — that's physics. Stud Finder shows what the sensor actually sees, so you can trust every beep. For structural decisions, confirm with a dedicated tool.

PRO, KEPT SIMPLE One small one-time purchase (or a low yearly plan) unlocks metal-detector mode, alerts, sensitivity and saved finds. Family Sharing included.

Sweep the wall. Trust the reading. Drill with confidence.
