Gold Finder Metal Detector is an Android app developed by RuBi that can help you find your lost gold, rings, bangles, or any metal base item with your smartphone. The app uses your phone's magnetic sensor to measure the magnetic field values in the environment, essentially turning your Android device into a true metal detector. The app is free and works on Android 9.0.

This app is easy to use, simply press the find button within the application, and the gold metal detection process will start. If there is any metal base item or gold base in your surroundings, your smart device will beep loudly. The app can even detect hidden metals and electrical lines through walls. The quality of the app is dependent on the quality of your phone's magnetic sensor. The app also allows you to create a cool magnetic field intensity graph and determine how much gold, iron, or silver you possess.
