Create different frequencies, drive insects away or compare your hearing ability with your friends and relatives and share your results! Or watch others straining their ears to find the sounds that cannot locate you. Party fun is guaranteed!

Attention: If you want to share your results with others, first test your audible frequencies, then mark under the speakers your lowest audible tone and your highest audible tone (stored only temporarily). A small hint: the chart will show you what other frequencies of your age are still possible to reach.

Decent app, has the potential to be AWESOME !

I have used this app for many different projects. From sound effects while making two-way radio training videos to actually testing and activating voice pagers by playing the tone sequence through the radio’s microphone and more. It would be nice if I could save some of the sequences I have created but since there’s not a comparable alternative app that does what this one does, I’ll settle for what it offers for now.

If you are willing to spend $0.99...

you end up with an easy to use app that works well, but has no bells or whistles—well some frequencies sound like whistles to me ;)

Limited function, ruined by ads

I wanted to have an app for testing speaker system response, I thought this app would do it. Seemed ok at first, but without paying to unlock, the app is really slim and only has one function - play a tone. Then suddenly a full screen ad took over that I couldn't seem to close without just terminating the app. That's a deal breaker for me. I'll find a better app.
