It's okay for quickly finding frequencies that are feeding back, but without the ability to import calibration files from something like a Dayton iMM-6C it's hardly pro. I've had this for many years, haven't seen any development in a long time.

1. Why doesn't this app have weighting options in the measurement settings? All Pro RTAs have it. It would have been nice to have a A weighted and C weighted measuring profiles. 2. Also how to calibrate it is not clearly mentioned. I have excellent pink noise in my studio. Would like to calibrate it on my phone as closely to a standard RTA as possible. Any help would be greatly appreciated. Thanks.

Works well. Has the basic FFT functions, but doesn't include signal generation. My only beefs are that the peak hold line is so thin that it's nearly invisible; there's only a bar display mode, no line mode; and no way to load a mic cal on top of the internal circuitry cal.

To those who get crashing when calibrating here's the fix. Before clicking on continue to start calibration, make sure u are in a dead quiet environment. Then give it at least 15 seconds for bars to lower. Then turn up your pink noise. It should work fine then.

Hmmmmmm tring to measure the peak noise level, when ever i press the start button i always get a sharp peak which is useless as soon as you start, the background noise was measuring about -70 dbfs but the peak at the start saw spiking at anything from between -50 & -8 yet there was no noise present, so it renders the peak level detection useless.

Somehow I became a beta tester. I don't mind, but? Well I bought the original RTA, now it's the beta RTA. When I click on your website it's gone. Even the pro beta version suggests I get your noise generator, which only works with Android9 and under. This is basically abandonware that still works .

This is as PRO as my little pinky. There's no option to load up a calibration file and manual calibration is really bad... I had to refund this app after trying it out.

Great app. Really wish someone would make possible to view 2 traces from 2 sources i.e front speaker and external inputted source via the trrs mic input. So you could measure the output of your console vs speaker reference like smaart.
