About this app
Turn your device into an AC magnetic field meter by using its magnetic field sensor.
Measure the RMS values from AC magnetic fields.
Fast Fourier Transform (FFT) to obtain the magnetic field frequency spectrum.
• Gauge to show the RMS B-field in the X,Y or Z directions, or from the magnitude. Or alternatively show the DC magnetic field.
• RMS graph to show the gauge readings over time.
• Lower display shows time series data or a FFT from it.
• Peak indicators for the frequency spectrum.
• Save graph data to file.
• Units of Gauss or microTesla.
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.
This app is designed for indication and educational purposes only. Always use a suitable calibrated more accurate device appropriate for the situation when required.

Using this app in conjunction with a 3d compass app I was able to detect moving cars a few hundred yards away and obtain directional data as well as details of car geometry. Likewise I was able to explore super low ELF radio phenomena. Pretty neat, the lower x,y,z, output is less than intuitive however, you should combine the features of your gaussmeter app with this baby and incorporate a compass needle as an alternative to the xyz. Beyond that this app is pretty detailed in the output!

Best app in its class. Finely turnable, logarithmic or linear results, AC or DC coupling. Decent FFT visualization. I couldn't ask for more. Thanks for the excellent free app.

Nice UI, but it doesn't work. All the app does is measure movement in the accelerometer. Jiggle the phone, the graph responds. Hold the phone still near a known Ac source, nothing registers... unless you jiggle the device. It's the accelerometer... not the AC field.
