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.
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.

Magnets: toys are fun

Now a lefty

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.

Review EMF detector app

Old faithful player giving up

Sitting in a small den room with so many devices, smart tv, two printers, I pad, cordless phone, router, electric meter on wall outside made me thinking about what exposure Emf I was around. I thought it would be really high, but this app results are medium. Still too much emf exposure on a daily basis. This app was easy to use and other reviews make me feel confident in the results. I would need to compare with another device but just have not got around to purchase one. This app is convenient. Also, had a problem last year with a Fitbit device, irregular heart beats, took the device off one day in the car for some reason and about 45 mins later I noticed the irregular heart beats stopped. I think I may charge that up again and test it too

The upgrade is a lie


I do like this app because it’s consistent with its readings. But that’s about it to like about it. There’s no other options or settings with using the meter. I bought the upgrade and it does come with ad free unlimited EMF reading time but it doesn’t alert you when you are around high exposure unless the app is open. The way they explained the upgrade is that you can be alerted when you are walking around high exposure. But why TF am I gonna be walking around everywhere with the app open? That’s stupid. If I have the app open I don’t need to be alerted cuz I can see it on the MF screen. So what’s the point of being alerted if I have the open? But there’s no way to adjust the alerts. Even with the sound option turned on, it doesn’t beep or notify you without the app being open. So don’t get the upgrade unless you plan on walking every place you go to with the app open in your hand.
