Stud Finder vs Stud Finder Pro

STUD FINDER – WALL SCAN Find studs and metal behind walls using your Phone’s built-in sensors. Stud Finder – Wall Scan turns your Phone into a simple, reliable wall-scanning tool. Scan walls in real time to locate metal fasteners commonly found in wooden studs, helping you drill and mount with more confidence. Designed for DIY projects, home mounting, and everyday use — no extra tools required. HOW IT WORKS Stud Finder uses your Phone’s built-in sensors to detect magnetic anomalies behind walls. These anomalies often come from steel nails or screws used to secure wooden studs, as well as some metal pipes or conduits. As you move your phone slowly across the wall, the app provides live visual, audio, and haptic feedback to guide you toward areas of stronger magnetic signal. KEY FEATURES • Real-time wall scanning • Live magnetic strength meter • Edge and center guidance for detected objects • Audio and haptic feedback while scanning • Adjustable sensitivity • Simple calibration for better results • Scan history saved locally • Clean, distraction-free interface USE CASES • Mount TVs, shelves, and cabinets • Locate stud areas before drilling • Reduce guesswork behind walls • DIY and home improvement projects STUD FINDER PRO Detection history, full 30x sensitivity, and the bubble level require Stud Finder Pro — a one-time purchase or a 24-hour pass. IMPORTANT LIMITATIONS (PLEASE READ) Stud Finder is designed to assist — not replace — professional tools. • Detects ferromagnetic metals only (such as steel nails and screws) • Cannot reliably detect wooden studs without metal fasteners • Does not safely or reliably detect live electrical wiring • Accuracy depends on wall thickness, phone model, movement speed, and nearby interference • Results improve with slow, steady scanning and proper calibration Always follow standard safety practices when drilling. TIPS FOR BEST RESULTS • Move your phone slowly and steadily • Calibrate before scanning • Avoid nearby metal objects or electronics • Scan the same area multiple times for confirmation PRIVACY All scans and data stay on your device.

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.
