Stud Finder: Metal Detection

About this app

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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://mobilegames.cloud/studfinder/privacy-policy.html
