Cómo funciona

01

Elige tu objetivo

Dormir, calmar o concentrarte — y una frecuencia diseñada para ese estado mental.

02

Ponte los auriculares

Dos tonos ligeramente distintos crean un ritmo binaural que tu cerebro sigue.

03

Déjate llevar por el sonido

Añade ruido, lluvia o mar y deja que la sesión te lleve.

Generado en vivo, no una lista de reproducción. La mayoría de las apps repiten las mismas grabaciones. BrainSync sintetiza cada sesión en tiempo real — tonos precisos que nunca se repiten — con visuales animados y relajantes.

The science behind the sound

Binaural beats work by playing two slightly different frequencies — one in each ear — causing the brain to perceive a third tone at the difference frequency. Research on delta-wave entrainment (0.5–4 Hz) suggests this can support slower brainwave activity associated with deep sleep; alpha and theta entrainment (8–14 Hz) is studied for relaxation responses. BrainSync synthesizes these frequencies in real time so each session is precise and never a loop.

BrainSync is a wellness audio app, not a medical device. Binaural beats research is ongoing — we make no clinical claims. If you have a medical condition, consult a professional.

Frequently asked questions

What are binaural beats?

Binaural beats occur when each ear hears a slightly different tone. Your brain perceives the difference as a rhythmic pulse, and research suggests your brainwaves can synchronize toward that frequency — a process called entrainment. BrainSync generates these tones live using your device's audio system.

Do I need headphones?

Yes — headphones (or earbuds) are required for binaural beats to work. Each ear needs to receive a different tone in isolation. Speakers mix both tones in the air before they reach your ears, so the effect is lost. Any standard wired or Bluetooth headphones work.

Is it free?

Yes. BrainSync is free to download on iOS and Android. Core sleep, calm, and focus sessions are available at no cost. Some advanced features may be unlocked via optional in-app purchase.

Is it safe?

Binaural beats at comfortable listening volumes are considered safe for most people. As with any audio, avoid high volumes, especially for extended periods. People with epilepsy or seizure disorders should consult a doctor before use, as rhythmic audio stimulation may not be suitable. Pregnant women should also seek medical advice first.

Do I need to be still or meditate while using it?

No. You can use BrainSync while winding down for sleep, studying, working, or simply relaxing. The sound does the work — no meditation experience required.
