Use the magnetic field sensor on your phone to take EMF readings. Works like a 3 axis EMF meter. Displays EMF in milli Gauss (mG) or micro Tesla (uT). Uses include ghost hunting, paranormal research, finding sources of EMF radiation, monitoring EMF levels, and/or curiosity.

Instructions for use:
Preferences can be found by pressing the menu button. Many display options are available to customize what is on the screen.
The range on the meter can be changed in the options or by sliding your finger up or down on the screen. The left side of the screen adjusts the minimum, the right side adjusts the maximum. You can lock or unlock touch adjustments through the menu.
Custom color values can be set for the text. Sound can be enabled and customized in preferences, default is off. This will play a tone at a rate determined by the EMF reading, similar to a Geiger counter.
More detailed Instructions are available from the menu within the app.

Added Features in Paid Version:
Full Graph functionality
Baseline Mode
Auto Ranging Function
No Ads

    Do NOT place your phone onto a neodymium magnet! Unless you want 100,000+ mG. But I wouldn't bother my phone is stuffed now because of that xD
