Magnetic Field Detector
Here're the features of this app:
1. Metal Detector: By test, some metals, which could react with the magnetic, such as steel, iron, they could be detected by this app.
2. Shows current EMF value, in uT(microTesla)
3. Vector by (X, Y, Z)
4. uT/Time Graph
5. Vibrator Control
Keywords: Metal Detector, Megnet Detector, Megnetic Field Sensor

Looks OK and works well, but doesn't handle sensor hangs very well. Exposing the phone to a 60Hz field around a motor or transformer seems to hang my One S' sensor until it moves away from the field, causing the app display to hang as well. All apps seem to have this problem, so it's a problem with the sensor, not the app. But the app should notice the sensor is hung (taking far longer than average to respond) and indicate something instead of hanging. Other than that, it works very well. The "Home"/"More" buttons at the bottom are also too small to be tapped easily and should just be menu items or standard buttons instead since they're not very useful.
I have a Samsung Galaxy S7 and it works fine. I needed to see if I had my 2 sided electric blanket on correctly. I laid the phone on the blanket and turned on the power. Bingo, small sine waves on the screen. Moved the phone to the other side of bed and no sine waves. Great tool for AC power tinkering.
Functions as intended on my s2. For those that don't know, the phone has 3 sensors that measure the earth's magnetic field to create like a 3d compass bearing. I wouldn't bet on the accuracy of the sensors, but for general use, it's good enough.
Program does not work on my Samsung Galaxy Prevail smart phone. When I installed it, and opened the program, it did not start. It just simply went back to the main home screen. Someone needs to fix this app.
Love thus app, it works on my phone and my phone has no magnet sensor, wish it could detect stronger fields like my neo magnet
Once i had it Crashed on Android 4.4.2. Not worked even once. So uninstalled. But then changing my phone, i saw it works. So increased the rate.
All it does now if makes the phone vibrate constantly. Worked OK when first installed then next time it just buzzes. I'm sure it's a bad update. Uninstalling immediately.
Seems to be working well, I have found all the magnets I'm my house. The app itself runs smoothly.
Will not even open and like one other reviewer wrote, just vibrates phone...out of nowhere.
EMF... NOT.. Metal detector yes... Unless my bed frame is putting off an electromagnetic field and my knife and any other metal object I get it around app is junk for anything else
Does what it says. Works perfectly, nice GUI. It's funny that in the screenshot there's no ad visible, but it's there in the app.
It won't open at all and I just have a simple straight talk phone
Slowly slide a magnet next to your mobile device and watch how authentic and precise this app is! Bravo, nice work!
Very useful app to tell whether your mechanical watch is magnetized, at least with the Galaxy S8+.
Works great, but my phone keeps vibrating and I am unable to dissable the vibrations.
It really works.I put a magnet beneath my phone and it vibrated a lot
This s--- works! Does exactly what it says. No bs. Test with electronics, mp3 players, speakers to find out if works for your phone. Measures electrical fields
Useful but layman doesn't understand what's going on
Works with my S3 but not my S4 Tablet. Kept crashing.
Before downloading I did not be leave that it was real .great app it was real
Appears to be an effort to keep the rating low...ir works well for me.
This apliccation works great because actually I have a magnetic sensor, so I recommend this app!!
When I got a magnet and moved it near my device it worked! And I recommend it
Don't download it would is a piece if crap it won't even open.
App simply refused to open on my Android 7 phone
Very good but it should be extended to measure the efficiency of an anti radiation chip.
Give settings to turn off vibrate
Simple, easy to use, just works as intended.
You need sensitivity control, your app is the only one that goes over 500ut from a known power source of 30 amps (others reg 75-90ut), so high when you move away from the source it still registers until you restart the application. In general it is too sensitive or has no buffer at all.
