A decent free FFT app. I’m not sure of its accuracy, but that may be a factor of the iPad microphone too. It has an easy to use display, and clearly shows the peak of the spectrum, as well as a view or the waveform.
A little tweaky in resizing bandwidth but VERY straight forward and very useful for live sound control. No ads.
