Build a calm background mix for focus, reading or sleep — rain, waves, fireplace, fan, and
white/pink/brown noise. Save named presets, share a link that re-opens your exact mix, and use Pomodoro sessions if you want structure.
Everything runs locally in your browser.

Master controls
Gentle fade-in + soft limiter are always on. Optional volume cap is great for long sessions.
iPhone/iPad background tip
iOS may pause browser audio when you switch apps. Adding this tool to your Home Screen can improve background playback reliability.
Ad slot (optional)
This is a placeholder area for future ads. It’s hidden by default so the layout doesn’t jump later.
Session timer
Optional Pomodoro or a simple countdown. Great for “start it and forget it”.

How to use Focus Music
This tool is designed to be background-friendly: press Play once, then leave it running while you work.
It uses the Web Audio engine in your browser (no uploads, no accounts). Your last mix autosaves on this device.
If you want the most reliable “background playback” experience, try installing the Tools to your Home Screen. Some mobile platforms
restrict audio in the background for normal browser tabs.
Share links
“Copy share link” encodes your slider settings into the URL so you can bookmark or send it to someone.
You can optionally enable Start on load for a single-tap experience next time.
Safety + comfort
The mixer adds a gentle fade-in and a soft limiter to avoid sharp peaks. For long sessions, keep levels moderate and consider enabling
a max-volume cap.
Focus Music FAQ
Will this keep playing in the background?
On most desktop browsers it keeps playing while you switch tabs. Some mobile platforms may pause audio when a browser is backgrounded.
Installing the Tools to your Home Screen often improves reliability.
Does it save my mix?
Yes. Your last mix and settings are saved on this device. You can also save named presets and copy a share link that re-opens your exact mix.
Is it safe to leave running for hours?
The mixer includes a gentle fade-in and a soft limiter to reduce harsh peaks. You can enable a max-volume cap and Battery Saver mode for long sessions.
Can I use Pomodoro mode?
Yes. Choose Pomodoro mode, set work/break lengths and rounds, and optionally enable a soft chime at transitions.
