The basics are great, range zooming very bad. It kind of works, but in an unpredictable way...you have to randomly mash your finger on the amplitude and frequency scales until something useful hopefully appears. 5-star app with range scaling fixed, particularly with numerical input. FFT works great, very fluid.

Great App! Thank you!!! There are a lot of good voiceprint and spectral analysts apps out there for free, but I personally feel it was worth the money to pay to zoom to a specific frequency range where the relevant data that I need is. Other free apps don't provide that feature as well as this program does. It's the best I've seen for that feature alone, and It's the best we got on ANY mobile platform right now. You will need a good phone though for those high refresh rates, but it beats luging around a laptop and mic any day. -D

Basic but interesting app. I was hoping to be able to zoom in to arbitrary frequency ranges. Also, logarithmic scale has an artifact in the middle of the scale, no matter what frequency range is selected.

Works, I guess. Best summed up with a "Meh". Definitely not worth $5, stick with the free version.

Logarithmic scale is off The logarithmic scale feature which I paid good money for is not accurate. Middle C which appears a perfect 262 hz in the linear version appears to be 200hz or so. Also, you cannot rescale to limit the plot to a particular octave. I want this app to be able to tell me which notes are being played in a piano chord, but I cannot trust the scaling - please fix this before I up my rating. It would also be a great help if you could rescale in musical notes, so that you can clearly see which notes are being played

Was an awesome app, but does not work with Android 8. Seems to be unsupported. I am trying Spectroid and "Advanced Spectrum Analyzer Pro". Spectroid in particular had the same kind of waterfall display.

Great app I will give a star for each point implemented: 1. Subtracting of pre-recorded spectrum(e.g. noise) 2. Lower sampling frequencies(e.g. 4kHz, 2kHz) 3. Saving of spectrogram in text Or higher resolution image with time marks Other than that this app is much more accurate than tons of others I tested.
