Description
Info:
Not all android devices have a built-in magnetometer, so please be advised that it may not work with your device. Icon and text will indicate if device is compatible once application starts. Accuracy is dependent on manufacturer. A magnetic field sensor (also known as magnetometer) reports the ambient magnetic field, as measured along the three sensor axes. The measurement is reported in the x, y, and z fields and all values are in micro-Tesla (uT).
Settings:
For audible alarm and vibration on high field detection click on respective buttons to toggle. Change alarm sensitivity by clicking on reading and swipe seek bar to set.
Calibration:
If output readings fail it attempt to calibrate by gently shaking the device or waving the device in a figure 8 pattern.
Permissions:
Vibration: select whether device should vibrate when high signal is detected. Wake lock: Device will not sleep during operation.

Works with a variety of magnetometer sensors. 100% compatible with my S10. Readings are really accurate. Also works on some other older and newer devices I have.

This app is excellent. It detects ferromagnetic thing with compass and magnet of phone's speaker. It helped me find a plate of iron.

Great lil app to go with a flagship device with the right sensors in it. It could use a north-south feature to show the orientation of the magnet you are testing. Useful tool if you need this. Phis are free without any ads and that's a plus ya know. Thanks for that.
