Works well – EMF Meter Free Utility for iPod, iPhone Review

Very little learning curve. Test your surroundings to get a base line reading then conduct your test. Your base line will always be a little higher with this app then with a emf tool or at least mine was due to the phone putting out a little magnetics of its on. I use this app regularly now with our investigations.
