I have seen EVP and EMP detectors for the Android and the IPhone, anyone try these yet? They are simple.. I think. I have downloaded an EVP one but haven't gotten a chance to really test it out (i.e. haunted house, empty house). My cats keep interrupting when I turn it on in the apartment.

We used the ghost radar for android as an "experament" device and we loved it. I was skeptical at first but got great results. It works much like the PX or ovulus with a word database. Best of all it has a free version.

I have the Entity Sensor Pro for the android. It records evps and emfand charts the emf. And you can usean app called ringdroid to listen and isolate evps. Check it out.

The only word of caution I would suggest with using an Android for investigation, is make sure you turn on "Airplane Mode" so that you don't contaminate any EMF readings. The signal output from one of those phones can be pretty strong, and in the upper Ghz range. So it can raise havock with many EMF meters. This is especially true if you're in a low signal area, the power output gets ramped up on the phones when the signal strength is weak.

Very good advice. In addition to airplane mode, turn off all notifications and alarms. Make sure there are no interruptions from the phone.

I have the EMF & Ghost Tracker.. Love the tracker.. We went to Hearst Castle last weekend, it was an amazing thing to have! My 10 yr old is now obsessed with tracking

I have the Ghost Radar App and I don't think it works for me, although I am constantly having experiences. Although when I use it, I just leave it on. I don't try talking. I'm too chicken. hehehe I'm glad to see there are other apps to try. I will be trying them soon.

I'm highly interested in whether or not Ghost Radar works, it doesn't detect emf's but instead it supposedly detects changes in the quantum flux

I run Ghost Radar and Entity Sensor Pro (EMF detector and EVP recorder), so far they both appear to function as advertised though I have yet to go on a full on hunt with them. I'll get Ghost Tracker and try that out as well.

I am sorry, but any serious paranormal investigator worth his/her salt would never stake their reputation on a phone app! These devices are made for entertainment only and are not intended to do anything other than make noise and entertain people into thinking they actually pick up and identify ghosts!
