Brown noise, binaural beats and a rhythmic pulse, mixed however suits you, wrapped around a focus timer that adapts as the session runs.

What it's for

Something steady underneath you.

Some brains settle when there's something steady underneath them. This generates that steadiness live in your browser — brown noise, binaural beats and a rhythmic pulse, mixed however suits you, wrapped around a focus timer that adapts as the session runs.

Nothing streams and nothing downloads. The audio is synthesized on your device as you listen, which is why it works with the internet off and why it never loops or gets stale.

Reach for it when

The room is too quiet, or too busy.

You need to hold attention for a stretch and the room is either too quiet or too busy. Open-plan offices, cafés, a house with other people in it. Or when you're winding down and need something to occupy the part of your brain that starts narrating at bedtime.

Your first session

Start with a preset, adjust while you work.

  1. Start with a profile, not the mixer.
    Task Activation, Deep Work or Calm Brain. The presets are tuned starting points and most people never need to leave them.
  2. Set the timer to 25 minutes for your first go.
    Long enough to know whether it helps, short enough that you'll finish.
  3. Adjust the three channels while you work, not before.
    You can't tell what's right in silence — you can tell within about two minutes of actually working.
  4. Turn the volume lower than feels right.
    This should sit underneath your attention, not compete with it. If you're noticing the audio, it's too loud.
  5. Try Adaptive mode.
    Once you've done a few sessions. It shifts the mix as your session progresses rather than holding one texture for ninety minutes.
Getting more out of it

Three things worth knowing early.

Use headphones for binaural beats
The effect depends on each ear receiving a different frequency, so speakers won't deliver it.

The ADHD Sound & Focus Protocol covers which textures suit which kind of work, which is the part that takes most people weeks to work out alone.
Give it three sessions before deciding
Sound preference for focus is genuinely individual and first impressions are unreliable.
Honest about the limits

What it doesn't do.

Free, with no account and nothing to install. Your minutes, sessions and day streak are tracked on the device you're using and don't sync anywhere.

Audio tools support focus. They are not a treatment for ADHD, and nothing here replaces talking to a doctor.
