That is called an iphone and your troll was steve jobs. Don't worry though, he can't terrorize anyone any more.

I saw "EMF Detector" on his screen, and most smartphones CAN crudely measure magnetic field strength with the magnetometer that is more commonly used to determine compass orientation.

What IS baffling though, is how the app goes bananas and reads "UNSAFE EMF LEVELS" as I'm pretty sure a field strength powerful enough to be dangerous to humans would instantly turn a cell phone into a doorstop. Also, that EMF's = aliens or whatever.

Oh wow, ok... so it just says "RELATIVELY HIGH", well... that actually could be handy for something, though still kind of panicky.

The magnometer inside of an iPhone is a far cry from an actual instrument intended to measure EMF and such. Even as
a compass system, its reliability is dodgy and generally not considered to be all that great. (and has been shown to
be easily effected by outside forces, much more so than your everyday liquid compass) Many devices that use
magnometers as compasses use GPS (3G/4G location services) to improve the reading by correcting the direction based
on your heading. This is clumsy, obviously, as you have to be in motion for it to work properly, but it's commonly
used to improve your heading on something like an iPhone, if you have it enabled. Regardless, it's functionality
beyond that is pretty questionable. It'd be like taping magnifying glasses to a pair of reading glasses and saying
you now have "binoculars." Yes, technically there's a level of accuracy there and those glasses might magnify
something and work in a very literal, technical sense. But they certainly aren't REAL binoculars. The apps for the
iPhone that claim to function in these ways are, yes, pretty dubious at best. But, I apologize for suggesting that
a device designed to be an mp3 player/camera/cellular phone/pocket computer can NOT perform the same duties as a
specialized scientific instrument designed specifically to measure EMF. Clearly, the NWO/Ancient Alien/2012 folks
on YouTube can teach us all valuable lessons.

And, ironically, my iPod did some funky ass shit to my formatting. TECHNOLOGY IS WONDERFULS.

I don't even understand what you are saying. Who gave the impression that it was fine instrument? My point was supposed to be how this app isn't necessarily scammy psuedo science. The MEMS sensors in your average cell phone are accurate enough to pick out field strengths relatively stronger than the earth's, but not so accurate that everything makes them go apeshit. YES, THIS WOULD INADEQUATE FOR LAB USE, but is perfectly adequate for finding cable conduits behind drywall for example. Another acceptable use would be the placement of electronic equipment highly susceptible to strong magnetic fields. Who would use this? An extremely limited number of people. Why is there so many EMF apps out there? Because it's got everything beginning programmers could want out of an easy project.

The compass/GPS app I use shows the field strenth variable along with the heading. This is handy, because like you say, these things aren't the best. If I think I'm headed north but I'm showing a field strength an order of magnitude above normal background... I'm going to question my north heading.

Holy shit -- you typed that out on an iPod??

iPhones have featured functional magnetometers since 3GS

How in the world would an iPhone use GPS to function as a compass?

I like how it's psuedo science if StanleyPain isn't aware of it or can't understand it.

I can't believe it is not a linked tag.

The app doesn't do anything.

Points for the app using correct units, tho.

I mean sure, it's *possible* that a big iron ladder might confuse a shitty cell phone compass, but that particular ladder is part of a conspiracy that goes ALL THE WAY TO THE TOP.

I feel that this comment has made my creation of this entire absurd argument justified.

What, all three of them? And nobody here is asking where they can get this software because they're being targeted by the CIA.

Unless, of course, your tin foil hat is letting you read the SECRET comments left by the Reptiloids or whatever.
