How it works

How does the mixer work?

Each sound card can be turned on independently and its volume adjusted. You can run multiple sounds at the same time to create your own mix.

What are presets?

Presets are curated sound combinations for different focus modes — Noise Blocker, Deep Work, Relax, and Light Work. Click a preset to load one mix from that category, use the arrows to move through other mixes, and click the active preset again to turn it off.

How does the timer work?

Press play to start a countdown. When the timer ends, you get a chime. You can set the duration and enable a browser notification in Settings.

I can't hear any sound

Make sure the master volume slider (top right) is turned up and at least one sound card is active. Some browsers block audio until you interact with the page — try clicking any sound card first.
