Fascinating, but…

This app is fascinating and worth the price, but I’ve travelled 40 miles and been in two rural parks without getting a reading other than “saturated” and coded red for magnetic fields. So all the dots on my map are red.
I turn on an induction hotplate and the magnetic reading barely increases.
Can you address this with an update or documentation?
