Metal Sniffer ☆Metal Detector☆ for Android

This app detects nearby electromagnetic fields using the phone’s built-in magnetometer/compass. Depending on your phone, you can use it to detect metals up to 15cm away, and magnets from far, far away! Note that household equipment like TVs, and computers or even your phone case can affect readings.

===How to use this app?===
Very simple, just move the app around and read the measurements, if the magnetic field readings go over a critical level, the phone will vibrate, meaning a ferromagnetic material is nearby.

If the readings aren’t getting updated, make sure your phone is equipped with a magnetometer.

If the readings seems to be off, it means that your sensors needs to be re-calibrated, click the re-calibration button (refresh icon) for instructions.
