Update Review
Why?
Paid for the app in June only to be served ads now.
Simulated binaural phenomena; not actual hemispheric entrainment.
True binaural beats are a brain-only phenomena, and are not audible outside one’s own auditory perception.
To test the app I played it in my car, and my car rattled at the set pulsed frequency. … This should not happen with true binaural beats… again, it’s a brain-only effect.
Not working iPhone 17. IS 26.5
Full of ads
A MUST!
Great app How do we get rid of the advertisements at the bottom?
Lets you customize settings and save presets
It lets you customize the binaural beat frequency from 1 Hz to 50 Hz and the base frequency from 20 Hz to 1500 Hz so you can experiment with different settings and you can save presets for settings that you want to use again. I believe there is a timer also, but I like to play it while I sleep so I appreciate that they allow you to play it without forcing a timer.
For me personally, I have found that setting the binaural beat frequency at 4 Hz, the base frequency at 110 Hz, and turning it to a volume that I can lightly hear in my headphones has done wonders for my sleep. Make sure you use headphones for it to work properly.
