Metal Detector
FreeTurns your phone into a metal detector using its built-in compass sensor — live magnetic field reading in µT, strength bar, and a Metal Present alert. Works in Chrome on Android phones; only magnetic metals (iron, steel) are detected.

How it works: Your phone's compass sensor measures the magnetic field around you. When iron or steel comes near, the number goes up. When you press Reset, keep the phone away from metal — then the normal reading becomes the baseline.
- Only magnetic metals are detected — iron and steel.
- Gold, silver, copper or aluminium are not detected (they are not magnetic).
- It cannot tell which metal it is, or how deep it is.
- It is not as accurate as a real metal detector — a fun, estimate-only tool.
