There doesn’t appear to be a way to stop the tones. You can change frequency but it keeps gong until you quit the app.

Non functional. And to the moron who said anyone who can’t hear it isn’t “young enough” you are an imbecile who does not understand the purpose of this app or how anything in the world works.

It is a great app to prank ur friends at school and just cool like I was walking down the hallway with it on its just funny how the people react at my school to it
I now have tinnitus
Just a pro tip don’t play 18000HZ because and ad will play and no matter how far you through your headphones, the sound will continue to play through the ad just long enough to give you permanent hearing damage.

It doesn't do anything. The whole thing behaves like a screenshot. You Press the frequency, and aside from dimming just a bit, nothing happens.

This is such a good app. If I were you, I would definitely get it. If I could, I would rate it 100 stars. I love it.

So... I have no idea why I got this app... But it's pretty fun if you're trying to see how many hertz you can hear up to... Look, I'm weird. I'm a scientist. I needed this.
