Good to know

Questions, answered.

Works on any speaker No signup, no ads Nothing stored — ever
Do I need headphones?+

Not for most of it. Monaural and isochronic tones work on any speaker or phone — the app labels which preset is which. Binaural beats are the one mode that wants headphones.

Is it actually free?+

Yes. No signup, no ads, no trial timer. Open the tab, pick a state, press play.

Does it really work?+

Brainwave entrainment gently nudges your brain toward a target rhythm — people use it to settle into focus, calm, or sleep faster. Effects vary person to person and build with consistent, unhurried sessions.

Is it safe?+

For most people, yes. If you have a history of seizures or epilepsy, skip the 40 Hz flicker mode and check with your doctor first. It’s a wellness tool, not a medical device.

Do you store my data?+

No account, nothing to store. Your sessions live in your own browser — close the tab and they’re gone.

Brain Beats is a wellness tool, not a medical device, and isn’t intended to diagnose, treat, or cure any condition. If you have a seizure history, avoid the 40 Hz flicker and consult a physician.
