Out of all the RTA (well not really but) apps available this is the only one that can come close to displaying what is being played but the levels needed to calibrate speakers is far beyond any phone mic's capabilities. It's just recording distortion + limited frequency response at high and low extremes make these apps worthless for any real use in the audio world. Others can't plot points even close to a real RTA at any level. None can be used for the intended purpose your results will be awful

Does what it says on the box. Mostly it shows the non-linearity of my phone mic frequency response curve. But that alone is valuable as a baseline discoherence graphic. The app itself performs adequately.

Quite happy with it. I wish for an option to use normal basic colours without "3d" shading. Looks like winXP screensaver.

I use this app to troubleshoot problem frequencies when I'm mixing in a new room. Accurate and useful tool, thank you to the developers!

I have paid and downloaded the pro version and then I changed phones but lost my pro version. I have sent them the play store receipt but the developer doesn't reply.

Somehow I became a beta tester. I don't mind, but? Well I bought the original RTA, now it's the beta RTA. I don't understand. 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. If only there was a way to use an external mic for calibration and use! Hey guess what, 13 almost here. So there's your beta testing for you lose the suggestion to download your NG ! Option two make NG compatible with 9 and up !

I have the pro version but it's not working with Android 14 it's useless. The paid version is not operating and the demo version is operating kindly fix the bug. My phone is updated for Android 14 and now i am facing the problem

This apps ok great for RTA analyzer..the only thing that i think is this apps will better if we can load the calibration file for the calibrated microphone.
