A simple magnetic energy meter with audible warning and user adjustable threshold.

This EMF Meter Requires A Magnetic Sensor In Your Device To Work (Most Tablets Do Not Have Magnetic Sensors)

This magnetic energy meter (EMF) uses a user adjustable threshold which can be used as a trigger point to alert you of increased magnetic energy and also has a warning when its at its highest.

This app is different from others because the apps led lights values can be changed by the user meaning you can always see via L.E.D and display an increase in EM Field if its high or low. By using this you don't have to have high emf for the L.E.D to light up, it can be set to what ever low or high value you like to trigger and visually see the increase in EMF.
