Stud Finder Sensor vs Precision Stud & Screw Finder

REAL SITUATIONS WallScan WAS BUILT FOR The carpenter restoring an old beam — about to cut into hundred-year-old timber full of forgotten nails. WallScan spikes every time a nail comes near the surface, saving your saw blade. The electrician working blind — the junction box used to be there, but the drywall got patched and painted. WallScan locates the screws so you don't punch a new hole off target. The homeowner mounting a TV — slide your phone across the wall, watch the meter peak, drill into solid wood every time. The renter who can't make mistakes — WallScan tells you exactly where the studs are, so the shelf goes up on the first try. The DIY furniture maker reclaiming old pallets — find the buried nails before they ruin your planer or table saw blade. HOW IT WORKS Your iPhone has a built-in magnetometer — the same sensor that powers the compass. Metal screws and nails disturb the local magnetic field. WallScan reads those disturbances in microtesla (µT), shows them on a precision analog meter, and triggers a haptic and sound alert when you pass over one. KEY FEATURES - Live magnetic field meter in microtesla with a smooth analog needle - Color-coded scale, green to red as you get closer to metal - Haptic vibration plus audio tone when a stud is detected - Adjustable sensitivity for plaster, drywall, plywood and hardwood - Visual scan trace showing your sweep path - Calibration mode for clean, drift-free readings - 100% offline, works anywhere with no internet - Clean LCD-style interface, distraction-free TIPS FOR BEST RESULTS - Take off your phone's magnetic case and any MagSafe accessory - Calibrate by waving the phone in a figure-8 if readings drift - Move slowly across the surface, around 5 cm per second - Sweep both horizontally and vertically PRIVACY WallScan never collects your location, microphone, camera or any personal data. The magnetometer is a passive sensor that does not transmit anywhere. Your scans live and die on your device. Stop guessing. Stop drilling holes you'll regret.

Find the sensor first. Then scan with a bullseye aligned to your phone. Precision Stud & Screw Finder guides you through a quick one-time setup to locate the magnetic sensor inside your iPhone. That lets the app place the on-screen bullseye over the part of the phone actually doing the detecting—not simply the center of the screen. Place the phone flat against the wall, set the wall background, and slide slowly from side to side. A simple 0-to-10 Target Score, color-changing bullseye, and haptic feedback help you locate nearby steel screws, nails, metal studs, plates, and steel conduit. Broad, repeated signals can display a center line, while smaller localized signals stay on the bullseye. TWO COMPLETE SCANS FREE Try two complete wall scans before unlocking. Starting scan three or opening Level presents Precision Pro, a $3.99 one-time purchase with no subscription. It includes unlimited scans, the built-in bubble level and digital angle tool, history, target marks, and export. Results vary with wall thickness, target depth, phone model, case, orientation, and nearby magnetic interference. This app detects nearby steel; it does not detect wood studs, PVC, copper, aluminum, or live electrical wires. Always confirm before drilling.
