REAL SITUATIONS WallScan WAS BUILT FOR The carpenter restoring an old beam โ€” 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 โ€” 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 โ€” slide your phone across the wall, watch the meter peak, drill into solid wood every time. The renter who can't make mistakes โ€” WallScan tells you exactly where the studs are, so the shelf goes up on the first try. The DIY furniture maker reclaiming old pallets โ€” find the buried nails before they ruin your planer or table saw blade. HOW IT WORKS Your iPhone has a built-in magnetometer โ€” the same sensor that powers the compass. Metal screws and nails disturb the local magnetic field. WallScan reads those disturbances in microtesla (ยตT), 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. SUBSCRIPTION INFORMATION WallScan offers two auto-renewable subscription options to unlock Pro features (Unlimited wall scans, Pro sensitivity mode, Find studs / nails / pipes, No ads): - WallScan Pro Weekly โ€” $4.99 per week - WallScan Pro Yearly โ€” $29.99 per year (about $0.58 per week, save 88%) Payment will be charged to your Apple ID account at confirmation of purchase.
