  • I was looking for solfeggio tones then I got an idea to generate my on calculated multiple frequencies based on numerology. So my quest ends upon this app . I found this app perfect in many manners but one thing which I feel absent from this app is that I am not able to play multiple frequencies in a sequence with separate time limit for each frequency . This is best app but I am uninstalling it due to not fulfillment of required option. BEST OF LUCK

  • This is probably one of the least invasive apps I've come across with no adds. Tested the quality of many speakers and even found the resonance of my friends house. Fun app with many possibilities. I've had it over a year and have never had an issue with it one either of my phones. I happily bought it and feel it was one of my more worth while buys. KUDOs to the dev.

  • I'm not an audiophile, but this app was instrumental in helping me diagnose some buzzing and rattling in my vehicle's sound system and provided a very easy way for my dealer to replicate the problem in their shop, using the frequencies where I found the problems to exist. Prior to using this app, they had put in 5+ hours of debugging.

  • Very good app it does what it's designed for. I've been using the sound generator app for awhile now conducting test on my hearing. And I must say once again it's a very good app it has helped me to detect a so called dead space in my hearing. Which I'm very intrigued by because the sound generator reveals otherwise.

  • Great app for doing a quick frequency sweep when other test gear isn't around. Can you add an option to stop the phone sleeping as sleeping cuts the audio off and I have to let go of the scope probe to wake the phone again... Also can you add an option to remove the fade at the beginning & end of the sweep. Thanks!

  • Try it your self , it's really good. I thought the cool looking speaker icon was just an attraction. The Developers obviously worked on this. lifetime for me . Nice !.Update; had it a year , and the Developer maintains and improves this app. Definitely worth it for me.
