Tone generator

By michael heinz

Open iTunes to buy and download apps.


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.

Fantastic Layout

I once had an app like this several phones ago. Haven't been able to find one since. Not five minutes after the download my friends were finding anyway to seek revenge for the antics this application so readily made possible. I'm an absolute fan of my photo editing applications BUT , this is by far my favorite app on my iPhone. A million "thank you"'s for your time in developing this marvel. I recommend this one 100% ! ~JcO


It's great to see a tone generator that doesn't screw you over with in-app purchases. I don't see the problem that the iPad users are encountering, I have an iPhone 4, not like it makes any difference. Back on subject, thanks for making this app. It's hilarious to use in class and also extremely fun to use for such a simple concept. :)

Love the slider

Slider makes it very easy to scroll through tones quickly. Very much like the subtle frequency changes you can do (can change it as little as 0.1 Hz) Only thing that would make this app easier to use, is making the play/stop button bigger. Otherwise, just what I was looking for!
