About this app

A simple EMF detector! The detector is as ACCURATE as the sensor of your device.

Both Pro and Free have:
-->Magnetic Field B in microTesla,Gauss and milliGauss
-->Auxiliary Field H in ampere per meter
-->Recorder feature. Data can now be saved live on text file for later use on a computer. This requires the permission to read and write on external storage.
-->Keep screen ON button
-->XYZ, max-min and graphs.
-->The classic EMF meter with the needle and LEDs

The Pro has:
-->No ads
-->Recorder feature with timer. Data can now be saved live on text file for later use on a computer. This requires the permission to read and write on external storage.
-->Keep screen ON button
-->Sound notification for sudden EMF changes
-->A few backgrounds and skins for the detector.


Use this simple app to detect electromagnetic fields, metals, devices and amaze your friends with what your phone can do. Watch out because some people believe that sudden changes in the EM field might indicate the presence of paranormal entities :p.

The new themes offer the user greater accuracy, graphs of the displayed readings and even the ability to calculate and show the auxiliary field H which is calculated from the magnetic field. The simple theme makes it easier for inexperienced users to measure and study magnetic fields.

This app uses the magnetic sensor(compass) of your phone and displays the reading with a line of LEDs and a classic needle meter. You can switch between units of measurement (uTesla and Gauss) and change the range of measurement from the settings.

You can use this app to measure and study magnetism and electromagnetism, the earths geomagnetic field and more. It can be used as a detector not only for EMF but also for magnets, metals, devices and even (as some people believe) entities and ghosts.

NOTE that this app uses the magnetic sensor. If your phone doesn't have this sensor the app is NOT going to display any measurements. If you open the app and the readings are 0 it means that this app can't work on your phone. Also avoid getting your phone near powerful electrical devices like power transformers since you might damage it. Use at your own risk.

I really like this app. I feel like I get accurate readings from this meter. It has different meters to choose from and you can get readings of EMF waves in microTesla or milli Gaus. I use the free version. There is also an analog type meter. I just started using this meter, because I'm concerned that we may be saturated in EMF waves these days. Call me a conspiracy theorist.

I have gotten an understanding of how EMF readers are supposed to work and surprisingly this app works correctly. I was worried that the phone it's self would interfere with the reading but I have a normal baseline reading that's in the ball park if normal reading. If your reading is 0.3 - 0.6 Gauss then it's normal. Mine is right in the middle most of the time around 0.5 and 0.4. Like the app recommended.

Quite honestly I wasn't quite sure why I downloaded the app to begin with. I woke to find it was actually downloaded so I went ahead and tried it out. I've always felt very sensitive, now I can prove it feel the change in pressure, in electricity, and now obviously in EMF. It's been fun as a topic of conversation.
