This is the perfect app for those looking to find gold, silver, and other metals.

The app uses the phone's built-in magnetic sensor to measure the magnetic field in nature. This field varies from 25 to 65 µT (micro teslas) depending on the location.

The measurement is performed in real time and the resulting value is displayed on the smartphone's screen.

The measurement is performed on the smartphone's compass, which will help the user to determine the direction of the magnetic field in the environment.

The app can also be used to detect the location of cables behind walls, to locate metal objects, and to check the magnetic field of the earth and other electronic devices.
