Golrich - Metal Detector is a utility app designed for Android devices that effectively turns your smartphone into a functional metal detector. Utilizing the built-in magnetic sensor of your device, this app detects nearby metals by monitoring the strength of magnetic fields. Users can easily operate the app by simply moving their phone around, allowing for a straightforward and intuitive experience.

The app features smart detection, where the proximity to metal objects is indicated by rising magnetic readings and a corresponding beeping sound. A visual gauge displays the intensity of the signal, providing real-time feedback as users approach metal. However, it's important to note that the app is dependent on the quality of the device's magnetic sensor and is limited to detecting ferromagnetic materials, which means it will not identify non-magnetic metals unless they are part of a magnetic alloy.
