A free app for Android, by keuwlsoft.

This is an app that can be used as an indicator for the magnetic field. It measures the magnetic field strength with an internal sensor and provides the results in mG (milli gauss); 1 mG = 10 mV.

It has a built-in magnetometer and can be used with Android phones. The app also provides information on the magnetic field sensor and how to use it.

When the app is turned on, it will start measuring. The results are stored and can be downloaded to the device. The measurement time is also an indicator. It can be set to one of the three values (30 seconds, 1 minute, and 1 hour).

This app is designed for educational purposes.
