    Works as advertised and I will recommend it to friends and family. Thank you to the people put the effort to make available in future I will be looking first for apps from same source. To set up a pro-audio stage limitations of the phone microphone with phone hand held, come on it's not apps issue it would be the operator expecting accurate measurement .

  2. G Jacobs-avatar

    Wow. Am very impressed with the wide range of features. You can switch to 24khz bandwidth, slide indicator to specific freqs, step history in 0.1sec increments, generate white, pink, gray noise etc., and switch among several views of the graphical output. Two notes: 1) tap the ellipses (...), read the question mark icon, and see what the icons do. 2) Some users complained about accuracy ... they should realize that a cell phone mic is NOT a studio reference mic. It's the hardware, not the app!

  3. Mike Conrad-avatar

    Nifty. Easy to use and understand. dB levels seem very low though. (My stereo is coming in around 6 to 9 dB.) Advice welcome.

  4. Stanley Shen-avatar

    It took some time to learn the icons or functions, as they were not intuitive as apps made in the US, but after watching the instructions video with English subtitles, you will find this app to be very integrative. Great effort.

    I manage audio at a local church. I was looking for an RTA program because I want to learn more about speaker assessment.

  6. leland cason-avatar

    I want to use it for two different reasons. 1) to try to get voices of spirits recorded and 2) to desifer voices of the living. Lol. That are low or muffled from the backround noices. Will it help me with either one? If so how do i do it?

    Very good app by an intelligent developer. One suggestion, a manual would be nice in addition to the video.

  8. Richard Doss-avatar

    Love the test signals. If the phone had input it could actually check signal path and modulator products. Voice print would be nice.

  9. Sean Cope-avatar

    Very good functionality. Still don't know what the side scale is as it doesn't appear to be dB on whatever settings I am using.

  14. Ralph Bigio-avatar

    Need to listen below 25Hz... My microphone allows but your app does not. Love everything else, great features, including night mode! I'm sorry that I cannot use this. Any chance to update for lower frequencies?

  15. A Google user-avatar

    hard to use. Yes, its science, doh, but the app is less than intuitive. There's a science to good app design too
