SplitBrain science overview explaining what binaural beats are

Clear explanations

Grounded language, not mystical fog.

SplitBrain explains the basics of binaural beats inside the app: each ear receives a slightly different tone, and the listener perceives a third rhythmic difference between them.

Binaural audio works best with stereo headphones and steady tones. Individual response varies.

Available for iPhone

Focus, calm, and rest without the clutter.
