Stud Finder App: Wall Scanner
Detect studs & metals in walls
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Find the nails and screws that mark a stud, and the pipes you don't want to hit. Then let Wall View show you where the next studs are, right on the wall in AR.
Find the stud before you drill.
Stud Finder turns your iPhone's built-in magnetometer into a magnetic stud finder. It picks up the steel nails and screws that hold drywall to the studs, and warns you about the pipes, rebar and conduit you don't want to hit.
Lay your phone flat on the wall, let it calibrate, then slide it slowly. The gauge climbs as you get closer to metal, and the scanner lights up, beeps and buzzes when it finds something.
THREE SCAN MODES
Stud Mode: Tuned for the small, brief signal of a nail or screw. Follow the line of fasteners to find the stud.
Metal Mode: Less sensitive, so only larger metal like pipes, plates and steel studs stands out. A line of nails won't set it off, so you can tell a fastener from a pipe.
Deep Scan (Pro): The most sensitive mode, for fasteners set deeper in the wall that Stud Mode can pass right over.
WALL VIEW (PRO)
Found one stud? Point your camera at the wall and Wall View draws a line on it in AR, then marks where the next studs should be at your stud spacing: 16 or 24 inches, or 40 or 60 cm. Slide your phone onto a predicted line to check it, and tap to confirm.
Predicted lines are estimates. Doubled studs around doors, windows and corners can break the pattern, so check each one with the scanner before you drill.
FEATURES

• Live field strength in microtesla (µT) or milligauss (mG)
• Low, normal and high sensitivity
• Haptic and sound alerts: one beep for a possible stud, three for metal
• Save scans and look back at them later
• Keep the screen awake while you scan
• A step-by-step guide that walks you through hanging a shelf, from the first stud to the last screw
• Available in 13 languages

HOW IT WORKS, AND WHAT IT CAN'T DO
We want you to know exactly what you're getting.
Your phone's magnetometer senses magnetic fields, so it detects ferrous metal: steel nails, screws, pipes, rebar and conduit. Wood isn't magnetic, and no phone can detect it directly. Stud Finder finds studs the way a magnetic stud finder does, by finding the metal fasteners holding them in place.
That's why the app reports what it finds by signal strength instead of claiming to identify materials. If a reading in Stud Mode is unusually strong, it tells you it's likely metal rather than a stud.
Results depend on your device's magnetometer, the wall material and how deep the metal is. Detection is less reliable through thick plaster, tile, concrete or metal lath. Always check before you drill, and never rely on any app alone where there may be electrical wiring or plumbing.
