Stud Finder Sensor vs Pocket Metal Detector

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.

Pocket Metal Detector turns your iPhone into a simple magnetic field detector. View real-time magnetic strength in μT, track waveform changes, and mark signal peaks or detection data. Use calibration, sound, vibration, units, themes, and 3-axis magnetic data to adjust the scanning experience. Sensor results depend on your device and environment, and are not a replacement for professional equipment.
