Metal Detector & Gold Finder
Metal Detector
Find hidden metals with your phone's magnetic sensor.
UtilitiesMetal Detector turns your phone's magnetometer into a simple detector for nearby ferrous and magnetic metal, with an optional Signal Analysis panel for a deeper read. See what a phone metal detector can and can't find before you start.
📖About This App
Metal Detector turns your phone's built-in magnetometer into a simple metal and magnetic-field detector. Sweep your phone near an object and watch the live signal strength respond to nearby metal or magnetic fields, with an audible tone and visual meter that rise as you get closer. An optional Signal Analysis panel breaks the reading down further with a pattern breakdown, a fluctuation timeline and a stability score, plus a shareable report — unlock a scan for free by watching a short video, spend a pass, or get unlimited analysis with Pro. Because the app relies entirely on your phone's magnetometer rather than a dedicated detector coil, it responds best to ferrous metal and magnetic sources at close range and should be treated as a fun, practical tool rather than a precision instrument for treasure hunting or professional surveying. Metal Detector also bundles a small set of everyday device tools in its Tools tab — Compass, Battery status, Flashlight and Screen Light — so you have them on hand without switching apps. The app works offline and is available in 14 languages, with a free version supported by ads and an optional Pro upgrade for unlimited Signal Analysis and an ad-free experience.
✨Why Choose Metal Detector & Gold Finder?
Live Metal Detection

🛠️Key Features
Magnetometer Detection
Uses your phone's built-in magnetometer to detect nearby metal and magnetic fields, with a live meter and audible tone.
Signal Analysis
A pattern breakdown and fluctuation timeline give a closer look at how the signal changed during your scan.
Stability Score
A score that reflects how consistent the detected signal was, helping you judge the quality of a reading.
Shareable Report
Turn a scan's results into a report you can share — free with a video unlock or pass, unlimited with Pro.
Bundled Compass & Tools
A Tools tab adds Compass, Battery status, Flashlight and Screen Light alongside the detector.
14 Languages
Full interface and feature translations across 14 languages.
⚠️Limitations
- The magnetometer responds to ferrous and other magnetic metal, not to gold, silver or aluminium, which are non-magnetic and will not trigger a strong reading.
- Detection works best at close range; it is not a substitute for a dedicated detector coil and should not be relied on for treasure hunting or professional surveying.
- Background magnetic interference from the phone itself or nearby electronics can cause false readings; Signal Analysis's stability score helps gauge how reliable a given reading is.
❓Frequently Asked Questions
How does Metal Detector work?
It reads your phone's built-in magnetometer, the same sensor used for the compass, and converts changes in the magnetic field into a live signal meter and tone as you sweep near an object.
Can it find gold or deep buried treasure?
No. Because it uses your phone's magnetometer rather than a dedicated detector coil, it responds mainly to ferrous metal and magnetic sources at close range. It's a fun, practical tool, not a replacement for a professional detector.
What is Signal Analysis?
An optional deeper breakdown of a scan that includes a pattern breakdown, a fluctuation timeline and a stability score, plus a shareable report of the results.
How do I unlock Signal Analysis?
Watch a short rewarded video for one free unlock, spend a pass if you have one, or subscribe to Pro for unlimited access.
Why does the reading fluctuate even with nothing nearby?
Phone magnetometers pick up background magnetic interference from the device itself, metal structures, and electronics. The stability score in Signal Analysis helps you judge how reliable a given reading is.
What other tools does the app include?
The Tools tab bundles a Compass, Battery status, Flashlight and Screen Light alongside the metal detector, so you have common utilities in one app.
Does Metal Detector work offline?
Yes. Detection and Signal Analysis both run entirely on-device and don't require an internet connection.
Is there a free version?
Yes, the core metal detector is free and supported by ads, with Signal Analysis unlockable per scan via video or pass.
What does Pro include?
Pro removes ads and gives unlimited access to Signal Analysis without watching videos or spending passes. Subscription and lifetime options are available in the app.
How do I contact support?
Open the app's Settings menu and use the Contact Support or Feedback option to reach the Metal Detector team directly.
