Not accurate / noisy Tested this with a tone generator app, which makes a nice clean tone, as viewed in another oscillogram app: You can just barely discern a peak at the appropriate frequency. In real world applications this would not be usable.
Spectrum anal Only downloaded this because when it showed up in the store, it couldn't fit the whole title in. All it showed was "Spectrum Anal" 10/10
Please make a paid version to get rid of ads. - The tunable response is great, but somehow it doesn't quite behave the same as my old hifi used to. - If you could make this a dual channel display (smaller set of bars, but one for R and L) with a tighter tie in to the music it would be awesome. - Best one I've found so far, and very close to perfection.
Almost perfect Ad's spoil otherwise great looking app. Performs brilliantly. Let me pay to remove ad's !!!
