I am not a professional. I tried quite a few apps that were not user-friendly, and with limited info. Ultimate EMF Detector is easy to use, and offers more info than others. Another great thing is that ads aren't popping up, cutting off your vision or train of thought; it's a banner at the bottom of the page. Thank you!

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?

Your phone has a sensor that gets stuck on high readings. You don't need to restart your phone. Just calibrate the compass sensor

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.

Thank you for your review. The data come directly from the sensor of the phone unaltered and unfiltered.
