EMF Sensor Free

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). 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.Custom color values can be set for the text. 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.More detailed Instructions are available from the menu within the app.

I believed it worked until I discovered that if you slide your finger on the screen up or down several times you can adjust the lights like the volume. Or you can tilt your phone to the left or right and you see some big changes sitting in the same spot.

This app just a toy without auto range mode, there is no max range rest option which detects. So no need to say its good for your entertainment but not for ghost investigation

This is actually a metal detector it's not doesn't send any ghosts when you get by metal it goes to Red so this is actually a pretty good metal detector not a ghost detector

I was having trouble getting good sensor readings on an analog sensor. This app helped me identify the source of the noise that was causing the problem. Thanks

Hmm its ok

I'm downloading another emf detector to compare because this one shows I have extremely high EMF around me quite often n then just disappears. I'm curious if it's the app's function to randomly do that or a malfunction because there's zero cold spots, no chills, and no empathic feeling that someone's there.

it does work, and it's not as annoying as the other major free app in this category...

This is very interesting.

It works

Kev. L. Oct 9, 2014     

Works great! Easy and simple to use. I suggest turning on the sound option in the settings menu. To test out just hold a small magnet next to your phone to get a reading. (Small) is the key word as to not damage your phone!!! Like the really weak thin ones you find on the side of your fridge. The top right part of my phone produced the best results. Samsung galaxy S4 mini.

It's only as accurate as the sensor in your device and it's a phone not a hundred dollar real emf reader.
