About

Sonibral

Read full description

Sonibral is a living binaural beats engine created by a composer — built for sleep, meditation, focus, and creative flow. The project grew out of years of experimentation, searching for binaural beats that felt more powerful and more musical without actually using music. The result is something that has exceeded all expectations. Most binaural beat apps use a single tone per ear — one bicycle doing all the work. Sonibral stacks multiple frequencies working together, like a cycling team drafting behind each other. More momentum, less effort. Pick a brain state. Pick a tone. Put on headphones. The engine does the rest. Sound is synthesized in real time — slowly evolving, never repeating, unique in every session. Switch states or tones while playing and the engine morphs smoothly without stopping. It is truly alive. Try free for 7 days. Premium unlocks unlimited session length and custom timers for $3/month. Headphones recommended for the full effect. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
