Easy to use and extremely effective. I sleep every night with this pumping through my Bose.

Whatever your experimental design or desired frequency. This is the perfect app to observe binaural and/or tonal effects through headphones.

This app is amazing. Set to deep sleep and play behind some nice New Age music, and I’m out in two songs. Set it to focus and put it behind some new age or classical music or even soft rock, and I’m focused sharp as a life. Glad I found this app. Also works well with subliminal apps.

There are others out there but this one is so simple and you can tune your frequency perfectly. Sometimes use in conjunction with another app for fav background sounds

Great.

I’m an acoustician who is very adept in studies in hearing. These complex harmonics help me. I use this app on the quiet car of the train traveling to work each rising. Thanks for having an ad free version. Well worth it.

No matter what I do I can’t hear anything and see no troubleshooter.

Every few years, I decide to give binaural beats a shot, and end up getting turned off by the bloated, over-complicated, garish, unreliable apps I have to suffer through. Finally someone who gets that less is more and that simplicity is the ultimate sophistication. Bravo.

I purchased this app in July 2023 to run through July 2024. It worked beautifully until yesterday, when the app demanded that I pay for another year into 2025! I now cannot use the app AT ALL unless I subscribe for a second year. I’m being held hostage by an app and I would like a refund since I can no longer use the app through July 2024. Forcing me to purchase another subscription so that I can use my fully paid for current subscription is an illegal business practice!
