Golrich - Metal Detector for Android

Quick summary

Golrich — Metal Detector is an Android utility that turns your smartphone into a simple metal-finding tool. It uses the phone’s built-in magnetometer to sense changes in the magnetic field and alerts you when metallic objects are nearby.

How the app detects metal

• The app reads data from the device’s magnetic sensor and watches for spikes in field strength.
• When magnetic intensity increases, the app produces audible beeps and updates a visual meter to show the signal level in real time.
• To use it, you sweep the phone slowly over the area or object you want to check.

What you can expect while using it

• An easy-to-read visual gauge displays changing magnetic readings so you can see when you’re getting closer to a metallic item.
• Sound feedback (beeps) complements the visual indicator, making it simple to operate without staring at the screen.
• Operation is straightforward: just move the phone; no special setup is required.

Important limitations

• Detection depends entirely on the quality and sensitivity of your phone’s magnetometer — older or cheaper devices may give weak or inconsistent results.
• The tool only reliably detects ferromagnetic materials (iron, nickel, cobalt and their alloys). Non-magnetic metals (e.g., pure aluminum, copper, or brass) generally won’t register unless mixed with magnetic elements.
• Environmental magnetic noise (nearby electronics, power lines, or metal structures) can cause false readings.
