Is as advertised. You would think in a world of malware and data scams anything free may as well be a deal with the devil. This is not true here. I appreciate this developer for an extremely transparent and quality application. I tested the application on multiple known good EMF/MF of varying streingth with solid results. Al axis work perfectly, and I enjoy that the application shows you what sensors you have at your disposal and that it does not require any network connection. You rock!!!!

I almost blew my eardrums with this app. Cool app that looks like it works, but they need to fix a bug within the app. I was listening to music (normal volume) when I opened the app. I clicked the audible alarm toggle to let me know when it's above a certain amount and as soon as I touched the toggle buttom BOOOOM, my music is blasting at full volume. I quickly pushed the toggle button off and my music volume went back to normal. The developers definitely need to fix that.

worked extremely well and was very sensitive on my A71. I used it to look for slight magnetic fields from mineral samples to identify magnetite in them. I also used a NIB magnet with a known field strength to verify the amount of flux coming from my samples versus background and baseline. ALSO, its a free app with no ads, these developers deserve a round of applause, thank you !!
