About EMF Sensor
Use the magnetic field sensor on your phone to take EMF readings. Works like a 3 axis EMF meter. Displays EMF in milli Gauss (mG) or micro Tesla (uT). This data can be displayed on a customizable graph with optional auto ranging capability. EVP function now included that allows live audio graphing and recording. Uses include ghost hunting, paranormal research, finding sources of EMF radiation, monitoring EMF levels, and/or curiosity.
Instructions for use:
Preferences can be found by pressing the menu button. Many display options are available to customize what is on the screen.
The range on the meter can be changed in the options or by sliding your finger up or down on the screen. The left side of the screen adjusts the minimum, the right side adjusts the maximum. You can lock or unlock touch adjustments through the menu.
Auto Range Mode can be selected to affect the graph range, the graph and the UI range, or neither. It is suggested to select "Graph and Interface" to have fully automated range control.
Baseline Mode lets you set a baseline value that will be subtracted from the reading.
Custom color values can be set for the text and graph line. Sound can be enabled and customized in preferences, default is off. This will play a tone at a rate determined by the EMF reading, similar to a Geiger counter.
EVP Function:
Live audio data can be graphed and recorded. Once recorded, audio can be graphed and cut into clips and exported.
More detailed Instructions are available from the menu within the app.

Works on my Droid Razr M. Test it on a speaker. It'll spike when I place it under my subwoofer, which has a magnet, being a speaker. However, it does not work accurately on my girlfriend's plain Droid Razr for some reason. Maybe it works better on NFC capable phones with Android Beam?

This app is awesome. You can prove its real by moving it by speakers and watching it spike. Because speakers consist mostly of magnets. But either way it is cool thanks!

It seems to be more of a magnetic detector then an EMF sensor. S4

Would be helpful if it came with instructions on how to calibrate it, what "normal" parameters are, etc.

Not sure if it's working or not. If it is i am the most haunted place on the planet. The meter is all over the place, never a stable reading... Galaxy S5

Ever since the last update, its a mess. It doesn't hold a normal reading. It's lock feature does not work. It's readings are all over the place. It is absolutley not worth paying for. It does not work properly at all anymore.

It's movement creates readings. Don't buy this. Complete fake. Depends on your angle of the phone.

App is fully functional and a lot of fun to use. An app that actually does exactly what it says and if you say it is fake you obviously don't know how to use/tune it.

Works pretty well, I don't have a real EMF detector to validate the numbers, but when placed near a strong EMF source, reacts as expected.

I've been using this app for awhile now. Working great on the Galaxy S 5. Works great for magnet matching. Keep in up.
