This app is designed to help you locate metal elements such as nails, screws, and electrical wiring embedded within walls. It utilizes your phone's built-in sensors to detect these metallic objects.
To use the app, simply turn it on, place the back of your phone against a wall, and begin moving it along the surface. The app will emit a beep and display a red indicator when it detects metal.
The application is free to download and use, but it does offer in-app purchases and may display advertisements. These features help support the continued development and maintenance of the app.
The application works by using your phone's magnetometer. While it is designed for most modern smartphones, it is important to note that it may not function correctly on older phone models.
This app is useful for various tasks, including locating studs behind drywall for hanging pictures or shelves, identifying hidden wiring before drilling into a wall, or finding nails and screws that might interfere with renovations.
