Description

This is a very lightweight app that works as ametal detector using your Android device's magnetic sensor. It'svery simple to use, just launch it and it will show on screencurrent magnetic field detected, measured in µT, which is astandard unit. It also keeps records for maximum and minimum µTmeasured and shows info about the sensor itself.

Earth magnetic field is on average 50µT, so a value higherindicates presence of a magnetic field of some kind, probablyoriginated by the presence of metal, a magnet or an operatingelectronic device. Please note that some metals like aluminium arenot magnetic and therefore won't be detected by this app.

Please beware that the data accuracy depends completely ofdevice magnetic sensor and because of that values shown should betaken only as indicative. For professional uses it is better to usea standardized and calibrated sensor.
