Helps with my Tinnitus
     
by Leotony56 · August 18, 2025

This is a great tool for those that can us it as a sound therapy for Tinnitus. I set this app to control mine.. Works great!

Best app I’ve ever paid for
     
by Public eyes · June 12, 2025

In terms of straightforwardness and functionality this app is best in the market. I’ve tried all the tone apps for a very long time. THIS one has amazing attention to detail and fine tune functionality settings. But the main thing is that it works and it is reliable for a variety of needs in this area of utility. Also the dev is super nice and knows what he’s doing. All in all worth paying for imo great app!

Need to pay for what I want!
     
by leethal1234567890 · March 9, 2025

Not good! I needed to pay for all of its features including to extend the frequency range because the free version of the app only has a frequency range from 100 Hz to 10 kHz and I don’t like that! This app also has frequency sweeps but the free version of the app only makes it so the frequency sweep setting can only be set at 440 Hz to 1 kHz which I do not like! There are so many more features that I needed to pay for to even do those! The price for all those features is $8.99 but my mom and dad does not allow my to pay for apps that are like these!

You'd be better off whistling

U cant generate sounds under 100hz anymore... Including EVERY IMPORTANT SOUND (25.125hz limit of human hearing, 40hz, 60hz, 70hz basically anything that sounds good) and you cant even go that high either. Just put (SILENT) adds in the app instead of ruining it. And either way SPEAKERS CAN GENERATE SIGNALS HIGHER AND LOWER THAN 21Hz &amp; 21kHz (usually 8hz-25khz) SO EVEN IF YOU PAY YOURE NOT GETTING THE BEST<br/><br/>Edit to response:<br/>It’d cost me less to buy a dolphin and train them to whistle than to but this moneypants app. We will resist your sonic monopoly. Freedom is privilege unless extended to all!!!

Worst app I’ve ever tried in my whole life
     
by Tedonchi · May 10, 2026

This is the most poorly designed app I’ve ever seen in my whole life. I work with software and apps all the time. I’ve seen all kinds, but this takes the cake as the absolute worst. Horrible user experience. There is literally no way to just set a frequency and have it play indefinitely. That’s not even an option. The frequency constantly rises when you said it at one thing and it gets higher and higher and then it cuts off after a certain amount of time. There is absolutely no option to make the frequency stay steady. There is no option to make it play indefinitely. All of the commands and the buttons are grouped in a horrible way

Basic features paywalled after update
     
by Mike34341 · March 22, 2025

The use of an update to remove the full frequency range without paying a subscription is absurd and unacceptable.

Can’t do anything without upgrading to the paid subscription.

VERY SOLID APP!!
     
by TheTopDeadCenter · February 14, 2026

Seemingly almost zero complaints aside from the stop playback timer not functioning as intended. Other than that a very solid and a highly recommended purchase for those wanting such utility!
