Binaural Beats Brainwaves
Binaural beats and brainwaves for sleep, focus and calm, plus isochronic tones, ambient sounds, Solfeggio frequencies and guided breathwork. Over 500,000 downloads and more than 14,000 reviews at 4.6 stars.
What it is
A full sound library for sleep, focus and a quieter head, with the freedom to build your own. You get over 100 ready made binaural beats, dozens of ambient sounds that run from rain to brown noise, guided breathwork, and a set of Solfeggio frequencies. Layer a beat under a few sounds, each at its own volume, until a room sounds the way you want, then save it as your own mix. It plays in the background and offline, so it fits a real night and a real desk. There is no play button to hunt for. Tap a sound and it starts.
What binaural beats actually are
They are two slightly different tones playing one per ear, and your brain hears a third beat, the difference between them. Hold that difference steady and your brainwaves tend to settle into it. A steady sound in a noisy room makes sudden noises stop standing out. A steady pulse can do the same inside your head, giving a busy mind one even thing to follow. Because each ear has to hear a different tone, binaural beats need headphones. We make no claims beyond that.
For sleep, focus and meditation
A silent room is rarely silent. The door, the passing car, the voice down the hall, each one loud against nothing. The same interruption that wakes you up also breaks a focus block and pulls you out of meditation. Lay a steady sound underneath and those edges disappear. For sleep, choose a Delta or Theta beat, layer in brown noise or rain, and set the fade out timer so it drifts off as you do. For focus or meditation, hold that steady layer as long as you like. No headphones? Use an ambient sound or an isochronic track through any speaker.
