Highly inaccurate. It is impossible to hear above 18000hz so clear in addition that is reproduced by a mobile phones speaker.

Nice frequency generator, with noise in addition to sine and square. Would be great if there was notification when app is running in background whilst playing so it can be easily stopped.

This app is surious, the problem i cant hear more than 17000 but my friends do

And my dog, and neighbors. xD But really though, for all your frequency needs, this one has seemed good to me. Simple, useful, clean setup.

App is excellent, but you should bring frequency meter to the centre. The app looks congested. There should be a text box to set the exact frequency as it is difficult to set using meter.

They added so much advertising and random noises that it became unusable.

I hath used this as a disruptor at class where thy highest frequency doth bring pain to thy ears. But of greatest misfortune, I hath rotated my phone and an otherworldy beep brought thy attention upon me for now I hath my phone confiscated for one month.

Was unable to perform any tests as ads interrupted too many times. Uninstalling.

i just felt like installing it to see how it works and see how deep my headphones would go, i noticed how good the app would be to test bass on a headset

App is very useless when audible ads play every thirty seconds.

the loud beep every time you rotate your phone makes the entire app useless for me

Seems to do what it says. Really annoyed my 9yr old son :) Using it at max hz on a blue tooth speaker to try to drive a mouse cornered in my vent out of the house. Will report back... (Neighbors dogs do not like...)

Adi. W. Dec 5, 2016     

Use this tool to make music...And don't forget to hear to 528Hz because that's the frequency we vibrate at!!🤗

Can test out my subwoofer frequency range. Well done.

B. L. A. C. K. S. U. N. Jan 12, 2017     

Cool app. I can 20,000hz very well. Made my dog curl up into a ball tho. One more thing....why is information from my phone going to Japan?!

It delivers what it promises. Needs a "favorites" function, banking at least 10 (unlimited if possible).

Jer. V. Feb 23, 2017     

Best one I've tried but wish it went higher than 20000hz
