How it works
Three steps to a quieter mind.

Binaural beats need a separate tone in each ear. Any wired or wireless headphones work.

Set a timer and let go
From 5 minutes to all night. The session fades out gently when it's done.
FAQ
Questions
What are binaural beats?
When each ear hears a slightly different tone, say 200 Hz on the left and 210 Hz on the right, your brain perceives a gentle pulse at the difference, 10 Hz. Many people find these beats help them settle into focus, relaxation or sleep.
Do I need headphones?
For the binaural beat itself, yes, since each ear needs its own tone. The ambient sounds and music pads sound great on a speaker too.
Is it really free?
Yes. Resonance is free to download and use, with no ads and no account.
Will it keep playing when my screen locks?
Yes. Sessions continue in the background and end with a soft fade and a gentle chime.
Is it available on Android or iPad?
Resonance is iPhone-only for now. Android is on the roadmap.
