To listen to tones above 10k, you need to pay for the pro version.

Mit dem Update 02/25 ist der bassbereich <100Hz gestrichen worden. Der war sehr nützlich um raummoden zu finden oder Lautsprecher zu reconen. Damit ist die App in der kostenlosen Version für mich nach vielen Jahren nutzlos geworden. Nun ist die Funktion tiefe Noten zu spielen wieder da, und die App bekommt verdiente fünf Sterne von mir. Danke dafür 👍

I love to play around with this app and discover more and more features every time I touch it. The tutorial opens up the world of signal generation and so much more. Love this app! The pittance I paid to unlock the advanced features was well worth it. I am not a paid reviewer.

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!

It just crashes every time it’s opened. It’s up to date as per the App Store.

It would be great to have sweep sine in one channel while sweep burst in the other channel

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 & 21kHz (usually 8hz-25khz) SO EVEN IF YOU PAY YOURE NOT GETTING THE BEST Edit to response: 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!!!

Just about everything in the “pro” version was 100% free before February 2025. Google has free 1hz generators bro.
