About this app

The magnetic field sensor in your device is continually monitored and when the detection level is crossed, the counter is increased by one.

• Detect from the magnetic field in either of the X, Y, Z directions, or from the magnitude of the magnetic field, |B|.

• Detect on rising or falling past the detection level.

• AC or DC coupling option.

• Adjust measurement speed to one of 12 frequencies between 0.5 Hz and 2 kHz.

• Reduce double counts with optional no-count wait after detection.

• Graph to show magnetic field values.

• Counts indicated on graph and with optional 'click' sound.


Magnetic field sensors will vary in sampling speed, resolution and accuracy from one device to the next. For indication only.

Don't put a strong magnet too close to your device – you risk damaging the sensor/device. However, waving your device around in all three axis should restore the magnetic field sensor to good working order.
