A simple EMF detector! The detector is as ACCURATE as the sensor of your device.Both Pro and Free have:
-->Magnetic Field B in microTesla,Gauss and milliGauss
-->Auxiliary Field H in ampere per meter
-->Recorder feature. Data can now be saved live on text file for later use on a computer. This requires the permission to read and write on external storage.
-->Keep screen ON button
-->XYZ, max-min and graphs.
-->The classic EMF meter with the needle and LEDs
The Pro has:
-->No ads
-->Recorder feature with timer. Data can now be saved live on text file for later use on a computer. This requires the permission to read and write on external storage.
-->Keep screen ON button

-->A few backgrounds and skins for the detector.
Use this simple app to detect electromagnetic fields, metals, devices and amaze your friends with what your phone can do. Watch out because some people believe that sudden changes in the EM field might indicate the presence of paranormal entities :p.
The new themes offer the user greater accuracy, graphs of the displayed readings and even the ability to calculate and show the auxiliary field H which is calculated from the magnetic field. The simple theme makes it easier for inexperienced users to measure and study magnetic fields.
This app uses the magnetic sensor(compass) of your phone and displays the reading with a line of LEDs and a classic needle meter. You can switch between units of measurement (uTesla and Gauss) and change the range of measurement from the settings.
You can use this app to measure and study magnetism and electromagnetism, the earths geomagnetic field and more. It can be used as a detector not only for EMF but also for magnets, metals, devices and even (as some people believe) entities and ghosts.
NOTE that this app uses the magnetic sensor. If your phone doesn't have this sensor the app is NOT going to display any measurements. If you open the app and the readings are 0 it means that this app can't work on your phone. Also avoid getting your phone near powerful electrical devices like power transformers since you might damage it. Use at your own risk.

I've gone through the different EMF detectors on the Play Store, and this one is the fastest and most accurate I've found. I'm happy with it despite the ads because they're unobtrusive; so far, there aren't any of the annoying 5 - 10 seconds waits before closing. Actually, since I hate those other ones so much, I pretty much block them out of my mind, but I'm finding myself actually LOOKING at these ads, which is a first in a long time.

Interesting app. I haven't had a chance to use it as I want yet, exploring and all, but checked it against some known items with accurate results. When placed near my laptop, for example, it spiked. I set it and recorded it running on my table for an hour with almost no deviation in reading, which tells me it's not some fake designed video recording or some algorithm. Can't wait to travel and check it out more!

Hi at first it seems to work, although I'm getting an extremely high reading, every time, no matter where I'm at. Then after a short period of time, the reading goes down to around 40 and stays there. But when i restart my phone again and open the app, the app says the emf levels are at 450 again, and once again it drops way down and stays until I restart my phone again. Any idea why this is happening?

Results inconsistent. While there's a definite change near electronics, tools, doorknobs, anything metal, etc, the numbers are not the same near them or not. Tried continuously testing several objects, walking off and coming back, and the numbers kept changing compared to what they were before. Even tested returning to the middle of a room, not standing by metal, and the results changed several times. Setting it on the floor in the same spot sometimes provided different results as well.

Found out immediately my phone wasn't equipped with magnometer (sp?) and wouldn't be able to work on this or any other emf app. I really appreciate the information. It keeps me from wasting time trying different apps. Btw, I love this app and had used it about 1 maybe 2 years ago with a different phone and the experience was very personal and shocking. Was able to put certain things to rest , at least until I'm healed and better equipped to deal with them.

One of the only legit emf detection apps. Works consistantly. I have no complaints. I don't ever do reviews, but this is definitely worth the time. Excellent job devs. Looking forward to checking out your other stuff!!! I live in las vegas, one of the few cities where 5g network is being rolled out right now. The 5g comes in pulses. I was able to get a steady baseline reading and when a pulse would come, it quickly went up to 150 then 270 then 300 something! I was shocked to see it so high.

honestly a perfect app. it definitely isn't any of those fake ghost detectors out there, in a supposedly haunted place or a normal one you will not get any fake signals. you can fully trust this for ghost hunting or detecting active electronic devices that are hidden. used this app for years, highly recommended. works without internet to top it off.

Absolutely reccomend. As a person with a sixth sense (not strong because I can't see them all the time, most of the time I can feel where they are and how they're feeling) this thing is extremely legit. First I tested it on regular devices to make sure, then I went to the "hotspot" (usually where the strongest one is) and it went CRAZY. I can't wait to go use it when I go to a cemetery soon (with permission). If I could rate it beyond 5 stars, trust me, I would in less than a heartbeat.
