About Focus Mixer

Focus Mixer is a minimalist Pomodoro timer and ambient sound mixer designed to support deep, sustained focus in modern digital work. By stripping away unnecessary features, it lets you build your own ideal work environment with intuitive, distraction-free controls.

The Science of the Pomodoro Technique

The Pomodoro Technique is a time management method developed in the 1980s. By alternating short focused work intervals with brief breaks, it helps reduce mental fatigue and maintain high performance over long sessions.

Expected Benefits

• Sustained concentration: A 25-minute deadline prevents the brain from wandering.
• Mental wellbeing: Regular 5-minute breaks reduce stress from extended work sessions.
• Productivity visibility: Counting work in "Pomodoro" units helps you understand your own rhythm.

The Power of Ambient Sound

The 12 ambient sounds in Focus Mixer are carefully selected to maximize the sound masking effect.

What is sound masking?
It is the technique of playing ambient sounds at specific frequencies to make surrounding voices and sudden noises harder for your brain to perceive — effectively drowning out distractions.

Recommended Combinations

• Maximum focus: Rain × White Noise
• Relaxed creativity: Cafe × Birds
• Engineer mode: Server × Fan
