I’ve been using and making binaural beats, then Isochronic tones for my own personal research/curiosity for years and wished there was a simple app that did just this. Thanks for making this tool! It’s so stable and I love that it can play while other sounds are going . Could I request the carrier frequency range be increased to 20khz? Higher 12-14khz sounds are very nice on the ears with gamma brain waves in the 40-55hz range.

I bought this app to use with a Bluetooth speaker, since most binaural beats require headphones to be effective. The sliders allow you to set the exact frequencies you want, which gives you much more flexibility compared to some of the pre-made audio tracks available. And there are 4 memory buttons that you can use to save the specific frequencies if you find a combination that is particularly effective for you, as well as 4 built-in frequency presets to get you started. And the built-in timer is also incredibly convenient!The functionality of the app is perfect, and the only reason I didn’t rate it 5 stars was for minor issues with the interface. Because the main controls are sliders, there not 100% accurate. But clicking on the arrows doesn’t change the value of the slider, but takes you to a different page with a picker control. This page is also where the specific information about the different frequencies is located, but it would be nice if there was a centralized location where you could read up on all the different types of frequencies and their benefits. Basically things are a bit spread out, and for a paid app, I’d expect things to be a bit more organized. Other than that, it works great!

"I love the complete control over every thing, however I personally have been using binaural beats of 0.5hz and a carrier wave of 30hz for quite some time with very good results. Very disappointed this had such limited range. That's the one thing I would change, and would make it 5 stars. By limiting it to 4hz you cut off man brain entrainment modes." Edit- Issue was addressed by the developer, app now works very happily for me.

Whenever I need to hunker down and get work done, I start this app along with some background music and—idk if it’s the placebo effect or what—I can get stuff done so efficiently. Same with sleep. I listen to a podcast before bed and have this on in the background and I can feel myself being slowly lulled.
