SplitBrain

Presets that just work. Play in the background. Add natural texture when you want it.

SplitBrain preset categories

Pick a goal, press play. No sliders to fuss with—just Focus, Sleep, or Calm and go.

SplitBrain session screen with timer and controls

Stay in flow. Start a session, lock your screen, and keep working or resting—system controls handle the rest.

SplitBrain library and natural soundscapes

Gentle soundscapes when you want them. Ocean, rain, café, or forest under the beat—kept soft for clarity.

Headphones required for the binaural effect.

Built to be simple and respectful: on-device audio, no accounts, no ads. More in the privacy policy.
