Error reading audio Already open. Just installed on GS5.

Good app not the best This is a good simple app, but the frequency scale is linear not log, which is really silly for a spectrum analyser. Most of the plot is taken up by kHz

Nice tool I like seeing the fluctuations in RF fields using this app.

First of all, I think its awesome that you can even do this live FFT on a phone. I found a bug in that if you pause a plot, leave the app and come back, the peak trace disappears and you get a continual pop up message of "Error reading audio. Already Open?". An immediate add on that would really make this app is a draggable cursor or two that would display the value(s) at the cursor. What would put it over the top would be an ability to make waterfall plots and/or color maps of the FFT time history. I already paid a buck. I'd pay $10, easy, for color maps. This is on an HTC One M8.

Free = Limited Looks great, but ALL the useful features require the paid version. Linear frequency scale is worthless!
