JUNK

Junk
Does nothing next to hair dryer which is very high EMF output.
Best of 4 emf apps!
Of emf detector, radiation detector, metal/emf detector, it is the most simple to use and is quick to understand. I was not forced to rate it.
Very good app
Out of many magnetic field apps I use this one because the feature of being able to select AC in effect removes the earth's static field and permits just seeing the effects of AC fields, mainly ELF EMF I think. Great! Users should be aware that on AC if the sensor is moved about, the reading briefly jumps due to moving the sensor within the earth's field. No problem if you know why. Good app, developer responded quickly to questions.

Very easy to use
You can pick AC or DC and change units of measurement all on one screen. There's also a time graph associated with it.
?
Seems to do nothing. Maybe better use instructions?
Good fun for all young scientists.
I used this app on the iPhone 5. Very reactive to magnetic fields. I love the timeline setting.
Not very responsive
It seems that this app can detect B sometimes, but it is inconsistent and not calibrated. Back to the drawing board.
Fake
This app is a crap and dont work
Mr
Rip off app - display has no relation to magnetic field. Do not purchase.

Does what it says. Interesting possibilities.
Rip off!
'No compass! This device does not have the ability to measure magnetic fields!' Well, you could have said that in the sales info! But no! You took my money and then told me! Rip off! Not even worth one star!
Best one in store
Not the greatest, but much better than any of the junk that the app store has

Within 5 minutes of downloading this app I found a motor that was not running correctly. The problem has been fixed with no down time. What a great app!!!
