iPhone
Stop guessing where to drill. WallScan turns your iPhone into a real magnetic stud finder — find every
nail, screw and pipe in seconds. Drill once. Drill right.
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.
