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.
