- Anyone doing home improvement and DIY projects

- Handymen, technicians, and electricians
- Curious minds who want to know what's behind the wall

HOW IT WORKS
StudFinder reads the magnetometer (magnetic sensor) in your phone. As you move closer to metal, the magnetic field changes and the detector gauge rises. The point where the reading peaks is where the metal is. Scan the wall slowly, watch the gauge, and find the metal in seconds.

WHY STUDFINDER?
- No extra gear: carry a metal detector in your pocket
- Quick setup with a clean, intuitive design
- Great for beginners and professionals alike
- The same experience on iOS and Android

Note: Detection accuracy depends on your phone's magnetometer sensor and the type, size, and depth of the metal. StudFinder detects magnetic and metallic objects and is a helpful DIY tool, not a substitute for professional detection equipment. Wooden studs are not magnetic, so they can only be located through the metal nails and screws fixed to them.
