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.

Detects mG quite well on many smartphones including my Samsung S21 Ultra. Our team at The Underpresence attempted to calibrate this app with a traditional EMF device. Although the actual measurements were not spot on, strong variations in magnetic fields were immediately and accurately detected with both devices. If you're using this app for paranormal research, that's exactly what you're looking for. There is no preset milligauss or microtesla reading that indicates activity - you're looking for unexplained peaks or changes. If you happen to slide your finger along the left or right side, you may affect the size and sensitivity of the display and icons. Read the instructions if you find this happening - it's an easy fix.

This app used to be free and worked quite well. Now it's $2.99 mo and completely blank.

It is giving me 10 times more the real value

Is this calibrated with earth's emf

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

It's probably a good app, but unfortunately I will have to uninstall. My Alcatel Ideal 4060 isn't compatible. It says "No Sensor." 😞

Worth the money

Nice and Cool App. Still testing, so far so good. Thank You! 🍷☺

Yesssss!!! Thank Y'all

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!

Great fun even if it's not to true i still love this app

Results depends on phone hardware. Great app.. Thanks

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

Ger. A. Sep 26, 2014     

It does exactly what it suppose to do. I've had 3 different phones!

Roy. P. Sep 26, 2014     

Does okay

Eri. G. Mar 30, 2014     

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.

Ted. S. Aug 15, 2014     

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

Use to loosely measure the EMF radiation in my home to mitigate in my space as much as possible

Kin. H. Jun 27, 2013     

After going through a lot emf's a lil while ago I found this one and its the best on android

Real: absolutely. Accurate: maybe. I get similar results from several devices in the same place at the same time.

Good app, but for ghost hunting that requires readings in the 2 to 7 mg range, this app wont let you scan only in a particular range. When you set it to do so, it stills reads the earths field in the 500 mg range. Making it only good for readings of higher value. If you can somehow make it ignore higher readings this would be 5 stars for me.

I like that this app works as described. Very entertaining. Also LOVE that it doesnt have any permissions. Thanks so much!

I'd like to see a developer come up with an entire suite of paranormal detection and communication applications.

A. G. u. Oct 14, 2012     

Works perfectly. Put next to ipad and freezer and it soared. Perfect for ghost hunting and goes well with my night vision camera.

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.
