Magnetometer

Turn your phone’s magnetometer into a ferromagnetic metal detector. • Real‑time magnetic field indicator with a clear color meter: green (ambient), yellow (nearby), red (very close). • Works offline. No account. No data collected. • Optional Pro upgrade: removes ads. ⚠︎ What it detects: ferromagnetic metals (iron/steel). It does not detect non‑magnetic metals like gold, silver, copper or aluminum. Tips: test away from speakers/magnets; range depends on sensor and case thickness; if the meter saturates near a strong magnet, step back.
