I use this one on the iPad - Multi Measure 2 - https://itunes.apple.com/us/app/ ... -1/id933528345?mt=8
I place it ( upside down ) near the ground where I will launch/calibrate and move it up and around to see if the reading changes a lot. If it does I move to another location.

Why not just purchase a magnetic compass? Align yourself with magnetic north, walk 20 paces, turn around and walk back following the compass ONLY. If you don't get back exactly to your start point, you have a magnetic interference in the area.

You can get Android apps as well. AFAIK they use phone's own compass to measure magnetic fields.
