Very interesting results I found this app to do be very neat. I walked around the house scanning air, walls, doors, lots of stuff and found my walls and areas of doors to contain something odd. I tested again to assure there was no error and its detecting something odd. Great app!
As stated in description To the fellow Aussie who reviewed so poorly; clearly states it is not a calibrated tool but an indication of a field being present. The fact it registered at all proves it worked however inaccurate. Also 2x same brand phone /= sound science by any stretch.
Tested by an Engineer with a phd in electromagnetic compatibility At a training course held by dr tee tang in brisbane in march 2012, we tested this app on two htc phones on a known electromagnetic noise source, a 12v transformer that dr tang had done tests on. One phone under estimated the value by 800 times, the other phone over estimated by 200 times. Don't waste your time downloading this!
Incorrect This app was not written by a knowledgeable source. The units are incorrect to start with. 1 micro Tesla is 10 milligauss. Also, not sure where the 0.2 micro Tesla limit comes from. No function for calibration.

Usable, but it drained my battery after being closed.
News 1.2 : with units, limits are given, better field intensity estimation.
