Ooooo 4+

This app is perfect. Unlike the many others I tried, it works with all my other apps, not just music. So I can use it while listening to my podcast or watching tv etc using the same headphones. It does not come with preselected music, you can just play what you like in the app you usually use. At one point I had the audio from Ooooo, my podcast on Overcast, my app that beeps at me when I slouch, AND a game all at playinjg together nicely at the same time.

Unfortunately the app made me aware that I have hearing loss in my left ear because I couldn't hear the low frequencies on one side. Looked this up and was told it's because of age. So thanks for that. ;-)

I've been really bummed since I swapped from linux to my mac for work and this app has closed the gap for another open source app I was using. Thank you! No gimmicks just Binaural Beats 🙌

I wanted a binaural app to listen to while studying that was easy to navigate and didn't have gimmicky features. This is it! Bonus points for being able to adjust the tone, which adds another layer of customization to your listening experience, a feature I did not have on another app I used to have on my phone. There are some bugs, like the Timer button causing the app to crash, but since I'm using it to study instead of fall asleep I don't plan on using that feature much anyway. I'm satisfied.
