Pros: It works just fine as a magnet/magnetic field detector, even giving full polar orientation of the magnet in 3D. Impressive stuff! This singular feature gets it 2 stars, if it had been advertised as such, it would have received 5 stars. Cons: Does *not* measure EMF, even though technically my phone can detect very particular emf signals, like wifi, bluetooth and mobile, it doesn't utilise any of these antennas, and couldn't make much use of them anyway because android itself only has limited access to the data carried by these signals, not the raw signals themselves. It certainly can't detect 5G or terrahertz frequency emf. The only exception to this is the 405–790 THz range, which is visible light, and any phone with a camera can pick up. The myriad positive reviews are *very* suspect - with similar wording, and consistent syntax and error rate that suggests they are written by the same person, and they all claim the app has functionality that it does not. The developer also claims to have developed an app that can detect ghosts. Even if that were possible (it's not) it would require a wide range emf detector, as this is believed to be the best way to detect paranormal events. Again, not possible anyway, but if it were, you get the idea... I'm a very experienced software engineer, android user and have enough basic engineering physics to be sure everything I've written is true. I also cannot stand BS.

Easy to use app. Big diggits. Works fast. One can change between different measures, milliGaus, micro Tesla, ...(sorry if i mistaken spelling). It even has the Retro Old Fashioned style/interface of these devices from the time of my parents, and one can have good experience here, too.

Nothing wrong with the App it works great, you need to understand aviation method on DEW if you do you will know why it works better sometimes on a hard grounded surface, I own many an have study it for last 2years, put on record place in a lead lined box with only one opening don't move to slow when scanning it works fine, so do D.E.W. aviation tactics, good luck ppl , an great job app creator it does the same as my high end meter so thank you

Very good and legitimate app. My first test was to put it near the microwave to see if there was any spike and there was. My next test was a live electrical cable and it worked. My last test, an investigation. Long story short, I had intelligent responses that lit up my app like a christmas tree on command without anyone touching the phone. I would 100% recommend this app for any budding investigators. Thanks guys for a great app!

It seems to work, is easy to read, free with a low cost Pro version available and the ads are small unintrusive boxes at the bottom of the page and not a full page pop-up that obliterates the entire screen. I think that this is a keeper.

Performed two simple experiments, here's the results. Test one, placed phone between headphones with app on, turned headphones on and no noticable difference between on/off states. Test two, placed phone on cordless drill with app on and drill battery disconnected. No noticable difference when connecting battery, but the weird part is when I pulled the drill trigger. Readings actually dropped while current was flowing through the motor. You be the judge of the app's functionality.

This is a great app for detecting magnetic fields. Very responsive from my observations and fairly accurate. But as a previous post mentioned, it cannot detect wifi or microwave. I understand this is due to smartphone capabilities, but I had the impression from the Google play description that it could do more. *Noted that sounds picked up by the microphone and changes in light effect readings. I would give 5 * if the description was more clear.

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.

perfect put it next to 3 different speakers and it picked all of them up actually the sensor on my phone is very sensitive it works to well, "not a bad thing." ads are actually very minimal i didn't notice at first, all i have to say is great job and flawless victory. i tried several apps first i should have came here first. I'll send a video on how it works with finding a gps tracker and several other items this does register between 1200-1500 mhz so technically speaking it should have no issues

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?

I like this particular app bc right after I downloaded and open it the screen went right on to the menu without delay and when I picked several options there were no ads... most of all they make a great opportunity as incentive to be positive in a review about its function and that came without even having a doubt thinking about it. Great Job developers keep up the good work. Stay Winning!

Definitely seems to be functioning. Whether functioning correctly is another story. Upon nearing WiFi, or any cables, wires that possess electro- magnetism, readings change. Being a T.I. I'm concerned that I'm being irradiated specifically by The micro-wave which is a Tactic done to the Targeted. I'lll say if this app is downloaded and you do not have a decent under- Standing of how to read the scales, Graphs, and what it means, you will have a beautiful, colorful app that serves no purpose.

It's pretty cool, fun and it def works, I've used it to check for wires behind walls and other hidden electronic devices. The Natural earths magnetic field is around 30 to 60 micro Tesla and I seem to get an average closer to 40-45..at the end of a rechargeable device it shoots up to like 4k...which was cool to see a dramatic change. Not sure what a ghost would make the sensor do, have to read up on that. I recommend this app.

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.

Ok so I was skeptical at first, but as it turns out this is pretty accurate. To test its accuracy I've put it near power receptacles and light switches to see if the needle responds near other electrical sources that aren't tied to wifi or Bluetooth. To my surprise I get the needle to move everytime. Great job on this app Dev's, keep up the good work. Oh and I would definitely recommend this to anyone looking for a good EMF detector on your smartphone.

Enjoyable app to go around and test different electrical items. This app works well - I put my hand up to it and nothing happens. If I put something with a battery up to it, the level spikes. I have got a few spikes around the house where it shouldn't have went up. Very interesting. I am going to keep going around and testing hot spots in the house.

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!

My wife and I could never figure out why her cell phone signal was always low, or cutting out; we have the same model phones//now, and the models owned previously were identical, as well. We were able to identify the source of EMF Interference, and rectify the WiFi/Security/TV$, and other electronics. In addition, we were able to determine exposure levels, as well. My wife has had a double bypass, w/5 stents, and a pacemaker/defibrillator installed. Thank Y-O-U!!

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.

Works great on my low end phone. Tested in multiple situations and get clear, consistent results. Ads are non intrusive and the interface is very smooth and friendly. I'm dealing with emfs from some advanced technology and this at least gives me a chance to document and remove myself from the situation. Thanks for making it free. Best wishes, I hope you profit from your work
