EMF Radiation Detector Reader

unless you put a magnet to your phone then it kinda scrambles

App works how it’s supposed to. Detects RF signals accurately as far as I can tell. Pretty cool !

Advertisements block the readings

Gives indication but no legend to tell you what they mean.

The meter seems to detect magnetic material but it’s unclear if it is actually capable of anything other. Some points of reference for comparison or an explanation on how to interpret the data would be helpful but I suspect that to do so may pose some contradictions with apps actual capabilities. If I am correct in that assumption than providing a pint of reference would be irrelevant with no truly accurate usefulness to regard.
