Discover the electromagnetic fields around you in seconds.
Live in a healthy environment. Avoid the emf pollution zones.

Detect the electromagnetic fields near you, known as EMF. It's not necessary an expensive electronic equipment. Your device is already a sensor to detect EMFs.
Track when a high magnetic field has been measured while you take the mobile with yourself. A warning beep will be activated to warn you and prevent health problems.

Use "Electromagnetic detector" as a scanner or as a EMF detector to detect high risk wireless zones. Check if your bed is EMF free! Appliances, microwaves and sockets could be now radiating you. Check the RF Detector.
Convert your iPhone into a EMF Meter (electromagnetic field tester) or as a teslameter. By using the internal compass hardware. You can view the raw data of the magnetic fields that are all around you on a digital display.

Over a thousand research studies have linked EMFs to important biological effects.

EMFs have been associated with symptoms such as nausea, headache, fatigue, anxiety, mental confusion, memory loss, sleep disturbance, itchy or burning skin sensations, and skin rashes.
The electromagnetic radiation come from broken or lose wires behind the wall, or electrical socket, appliances and other electrical devices in the home. Finding pipes or other metallic objects under ground or behind walls. Detecting the presence of ghost. Clocks and radios near the bed may also contribute. Exposures to EMFs from cordless phones, cell phones, wireless computer equipment, Wi-Fi, etc.

Scientist, Teachers, Students, Engineers, all use EMF Meter's for detecting magnetic fields of all types.


-You can track when a high magnetic field has been measured and when, so the current time is stored.

-Warning beep near focus radiation.

-Detect the strength of Magnetic force fields on all three axis’s (x,y,z).

-Magnetic force is calculated in microteslas ( µT )

-Record your readings with a time & date stamp of each event.

-Store until 100 records.

-Send measures by email.

Please observe and respect the iPhone user manual and warranty if you intend to use your iPhone as a scientific device. We are not responsible for any damage that you or any other force of nature may cause to your device.
You may calibrate the detector by moving the iPhone in the form of an 8.
Note: This app will not work on an iPod Touch, since it does not have a compass hardware.
This app is intended for entertainment purposes only and does not provide true Metal Detector functionality. This apps uses the magnetometer to measure the magnetic field when the iPhone is placed near feromagnetic metal objects.

If you would like to have a feature added to this app. Please let us know, so that we can make this happen as soon as possible for you.

Download it now to prevent stay near magnetic radiations! (EMF).

Better if it showed microVolts

I like this. I sit in front of 5 computers, 6 monitors and a UPS. I decided to buy an EMF detector but didn't want to spend much money to find the source of an unknown problem until I was clear that there was something worth testing. First I bought a highly rated but inexpensive EMF detector. That showed no EM emissions so it was useless. Then a Google search showed this EMF Detector app so I figured I'd try it. I put my phone in front of a large laser printer and turned the printer on-and-off. Wow! The app went from near 0 to high then back again.
I would guess the app can't be too accurate but it's good enough at showing me emissions that I can compare. I may buy a more expensive, analog EMF detector (~$130) now that I know there is something to test.
Much of the information about EMF in the US is in microVolts so it would help to be able to switch between microTeslas and microVolts.

Magnets: toys are fun

My husband works with REAL EMF emitters due to his job: Tower operations. He has to wear a high tech meter which is much like a voltmeter. You wouldn’t use your phone to test if there was a live wire in your house to not electrocute yourself while installing a new outlet or light switch because 1) it’s impossible 2) not it’s purpose. This is a novelty app, a toy, and so I’ll give it a better than 1 star rating for functionality of the app, not its intention just development function, it works and doesn’t crash. But as for what it claims it does, it does not. Don’t pay for this. Play with it, test it, but remember it’s a toy. If you did spend money, I am sorry, it’s akin to paying for your coffee three times: first when you buy it, second when you tip too high for it. Your phone can not detect EMF. Period. A brand new magnet, out the package not near or having ever touched an electrical device emitted very high. A second magnet, same. My clock: nothing. My Fitbit: nothing. My stove: Nothing! A fridge magnet, omg dangerous. A flat quarter sized magnet for my clipboard: dangerously high. And only when I touch it to the phone. If you want a real monitor if you are truly concerned about EMF and your health, please do yourself a favor and put your money towards a real meter. Otherwise understand that this app and apps like this are a novelty item, a toy.

Hell at the Apartment complex

With Tomato plants spelled with an M, you know what I am talkin about, ohhh....this device points out where my upstairs neighbor is stuffing the wires. The lady in a prior review said this doesn’t recognize EMF but I think differently, I have readings in the 8s when the device is on the wall and .54 in clear areas. It works and is well worth the three bucks.

Your right, its not an official test guage but is giving me proper signals....you see from an early age I had the ability to feel energy ...... for instance, I can feel the battery of a watch on my wrist.

About a week ago, I felt a wave of energy on my hand while laying on my air mattress next to the wall. I would move my hand over the wall and feel the hot ( juice energy-not referring to temp) coming off the wall. When I received the app, it indicated the lines my upstairs neighbor was stuffing in the walls was putting out this energy. My chest face arms facing the wall where red and orange in color when i woke up in the middle of the night. I looked at my right eye in the mirror and noticed a red vein in the white area expanding and contracting from the aggravation of the energy pulsations.

The recordings automatically save to the phone and then I took a pic and saved to phone. These levels are ridiculously high.
I am concerned! I have felt funny in this room and now know why I dont sleep well.
