okay, so I don't know if this is possible for Driod, but I know that Iphone and touch have multiple EMF detector apps.

Of course, everybody by now knows what emf detectors are with like every tv station having some sort of paranormal show, and I would assume that an EMF detector would get very popular considering how other apps like Ghost Radar have become.

I don't know if an EMF detector would be possible, but hell I would pay $10 for the app myself if it worked. I know the ones on Iphone work with the compass feature or something like that possibly. Is this possible for Droid or anyone workin on it?

here are a couple that i saw from iPhone:
iPhone Apps - Ghost Hunter EMF by John Cotant : AppAdvice - AppBase

The Droid, like the 3GS has a built in compass to go along with the GPS. The compass detects the magnitude and orientation of the earths or whatever is close to its magnetic field. So yeah you could do this.

And I'm sure, if ghosts were real, they wouldn't have an electromagnetic field.

Thank you. I had no idea what an EMF dectector was. Without your post I stil wouldn't. Now I can live life in peace.:hail:

Here's a link to a Ghost Radar app Not EMF, but still interesting if you're into the paranormal. Ghost Radar v2.0.3 Application for Android | Tools

re:

well thanks but that ghost radar thing isn't exactly what I was looking for. I was hoping to just find an EMF detector. I think it would be a great idea for someone to make an app like that. The Ipod / Iphones have a ton of these apps for sale and are making a killing on their market. I'm sure it would be able to make a ton of money here on the Android market. :motdroidhoriz:

here's another Iphone 3GS EMF detector app. :
FastApp - EMF Detector - Utilities appstore and app finder for iPhone / iPod Touch, 3G, 3Gs

Droid totally needs an app like this..

Tricorder displays a running graph of EMF. Here's the link:

Tricorder v4.4 Application for Android | Tools

Thank you! That app works well but the magnetic field detector is somewhat weak. Still would to see one come out like the iphone ones

Just an FYI, tap the Vector section and it will go into Relative mode which will make the readings appear much more sensitive to minor changes in the field strength.

Why does the field strength change so dramatically when I rotate the phone in relative mode?

Why would anyone want this? No really!

Kirk and Spock would not be amused by this question.

I don't know much about this app, but a little experimentation with a magnet tells me the sensor knows in what the direction the magnet field is. For example holding a magnet in different areas show that the vector section at the top changes to a different corner when you move the magnet to a different corner.

So when you tilt the Droid is it measuring the magnet field more from the direction that you are pointing it at? This would explain why the magnitude changes depending upon the direction you point it at. I don't know, just guessing. Play with a magnet a little bit, and you'll see what I mean. However as you probably know, don't get the magnet too close or it will send the Droid into dock mode.

Put it up to an AC adapter and watch the alternating current.

the magnetic flux part to the tricoder app is pretty fancy but it still freaks out when you move the phone and there is really no indication to what the measure of the field is... there is just the half way up line and full way up line which is a bummer. Some one please make one a these!

Just released

I just released my Entity Sensor / EMF Detector on the Android Market for $4.99. Search for it or go to my web site: krugism.com Development.
Give it a try and let me know what you think about it.
Thanks.

I would really like to know if this app works for it's intended use. I am aware that electrical energy from just about any source causes EMF readers to spike, but I would love to know how this one works, as I can't find anything about it anywhere on the net. I don't want to spend money on it if it's no good.

Metaloid which is free in the market is a emf detector. Might want to check it out.

Yes, it does work. If you start the app, then move a magnet or any electrical device near the phone, the app senses the electromagnetic field and displays the change on the screen.
I've tried it around some haunted areas and have had some good results. I'm going to go another place hopefully this weekend and will video any results.
Also, you have 24 hours after purchase to cancel your sale and get a refund.
Give it a try and let me know what you think.
