The Best Tone Generator I’ve Ever Used.

I’m a musician, and this app has become one of my go-to tools. It’s not just another tone generator — it’s actually useful. The built-in keyboard that lets you hear each note and see its exact frequency is brilliant. It’s perfect for composing, tuning, referencing pitches, and reaching that low-end response — everything just works the way it should.

Most tone apps feel like technical utilities. This one feels musical. The layout is clean, intuitive, and it reacts instantly. Whoever designed it clearly understands how musicians think and work.

I have a request however door the developer. No, it’s a plea.
If the frequency range could be extended to 10hz and I’d love to see a VST3 / AUv3 / desktop plugin version of this. It’d be a perfect addition to any DAW — not just for testing tones.

This app is accurate, reliable, and free — easily the best tone generator I’ve found on mobile. Don’t change the formula; just give it a plugin version and it’s perfect. Please oh please.

Awesome app

It does what it says and it does it just fine. I use it with pair of bone conductor speakers and I can feel the vibration on my skin. The timer feature is great too. Thanks for this app and keeping it free.
