## Stud Finder Wall Scanner Tool

### Understand the Surface Before You Drill

Stud Finder turns the sensors already inside your iPhone into a practical wall-checking toolkit.

Use magnetic-field changes to locate possible metal fasteners, compare wall-knock acoustics to identify changes in

backing density, and check alignment with a built-in bubble level—all in one focused utility.

## Three Practical Tools in One App

### Metal Scan

Move your iPhone slowly across a wall and watch for changes in the magnetic field.

Metal Scan is designed to help identify repeatable signals that may be caused by:

• Drywall screws.

• Nails.

• Metal fasteners.

• Brackets.

• Metal framing.

• Pipes.

• Other nearby magnetic materials.

Because screws and nails are often used to secure drywall to framing, a repeatable vertical pattern can help you

investigate possible stud locations.

The app uses a slowly adapting baseline to reduce the effect of the Earth’s normal magnetic field and emphasize local
