Wall Stud Finder turns your phone into a digital stud finder. With the built-in magnetometer, it detects the weak magnetic fields of nails and screws securing wall studs, as well as larger metal objects like ac wires, pipes and rebar. It also provides basic alerts for live electrical wiring by detecting associated magnetic fields. Key Features: Stud Detection: Finds metal studs and locating the nails/screws within them. Pipe Detection: Identifies hidden metal pipes, conduits, and rebar inside walls. AC Wire: Use it to find AC wires, helping to avoid dangerous accidents. Simple Visual Interface: Provides a clear visual signal that strengthens as you move over a detected object. On-Screen Ruler & Protractor: Measure objects directly on your screen or use your phone as a quick reference for angles and dimensions. Level Meter: Transform your phone into a digital bubble level for ensuring your installations, like shelves or pictures, are perfectly horizontal or vertical. Construction Calculator: Quickly calculate required materials like paint, flooring, or lumber, and perform essential unit conversions (e.g., feet to meters) on the fly. Ideal For: Hanging shelves, TVs, pictures, and cabinets securely. Planning DIY projects like installing new fixtures or adding wall framing.

About

Stud Finder Pro

Read full description

Measure twice. Drill once. Stud Finder Pro turns your iPhone's built-in magnetometer into a precision wall scanner, the same sensor that powers your compass, calibrated to find the nails and screws inside drywall, plaster, and lath. Take the case off. Hold the top of your phone flat to the wall. Slide slowly. The signal climbs as you cross a screw, peaks dead-center, and drops on the other side. Mark the peak. That is your stud. Built for the moment between picking up the drill and committing to the hole. WHAT'S INSIDE A real-time magnetic-field readout in microteslas. A clean amber arc gauge that sweeps from idle to peak as you cross metal. Audio feedback that climbs with the signal so you can scan without watching the screen. Haptic confirmation at peak. A two-second auto-calibration that zeros out the room before you start. THE WAY IT WORKS Your iPhone has a magnetometer near the top edge, the same sensor your compass app uses. Stud Finder Pro reads it forty times a second, watches for spikes against your calibrated baseline, and shows you exactly where the metal is. Wood studs themselves are not magnetic, but the screws and nails that fasten drywall to them are. Find the screw. The stud is centered around it. HOW TO GET ACCURATE READINGS Remove your phone case. Magnetic accessories, metal-rich cases, and watches all skew the magnetometer. Hold the top edge of your phone flat against the wall. Slide slowly and steadily. Calibrate first by holding still for two seconds in an open area away from metal. WORKS ON Drywall, plaster, lath, and most painted wall surfaces. Concrete walls with rebar register strong signals everywhere, which is not what the app is for. DOES NOT DETECT Wood directly. Plastic pipes. Live electrical current. Non-magnetic metals like copper or aluminum. This is a ferromagnetic detector, not an X-ray. OFFLINE-FIRST PRIVACY No accounts. No advertising trackers. The magnetometer data never leaves your device. Anonymous usage analytics through TelemetryDeck only, no personal identifiers, no cross-app tracking. PRO TOOLKIT Pro unlocks unlimited scans, calibration memory, and the full-precision experience without any session limits. One payment, yours forever.
