    Nice app. Very useful! That's from my view as a long-term sound engineer.

    Great app all around, but doesn't show anything about 24khz, even though I bought the premium version and set the range to 30khz.. Any suggestions?

    The free version literally only measures the sound. It's suppose to measure EMF, but look at the first screen and tap the phone the lines will jump according to how loud it is. I don't trust to pay for the rest of the bs.
