How to Use

Focus Mixer combines a Pomodoro timer with 12 ambient sound tracks to help you concentrate. This guide covers everything from basic controls to advanced techniques, step by step.

Basic Usage

1

Choose Your Sounds

Click any sound button in the central sound panel to start playing it. A highlighted button means the sound is active. Turn on multiple sounds at once to create your own unique audio environment.

💡 Start with Rain or White Noise — they work well for most focus sessions.

2

Adjust the Volume

Use the slider under each sound button to set its individual volume. When layering multiple sounds, balancing the levels creates a natural, cohesive soundscape. The master volume slider adjusts all sounds at once.

💡 Try setting the primary sound (e.g. Rain) to 70% and a secondary sound (e.g. White Noise) to 30% for a good balance.

3

Start the Timer

Click the "Start" button in the timer panel to begin a 25-minute countdown. You can customize the focus duration in the settings (⚙️ icon). When the timer reaches zero, a notification sound plays and prompts you to take a break.

4

Switch to Break Mode

After the timer ends, switch to the 5-minute break timer. Ambient sounds continue playing during your break. If you want a change of mood, try switching to a different sound set.

💡 Gentle sounds like Birds or Bell are great for helping you unwind during breaks.

5

Save a Preset

Save your favorite sound combinations as a preset. Press the "Save" button and your current settings will be stored in your browser. Next time, load them back in a single click.

FAQ

Sound stopped unexpectedly

If a browser tab is in the background for a long time, power-saving features may pause audio. Bring the tab back into focus and press play again.

Does it work on smartphones?

Yes. However, on mobile devices audio may stop when the screen turns off. Set your screen timeout to "Never", or tap the screen occasionally to keep it awake.

Does it work offline?

Focus Mixer is a browser-based web app. Sound files are cached after the first visit, so basic functionality is available offline once the page has been loaded.
