## What is Stud Finder Sensor?

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.
