Stay Focused with the Pomodoro Technique and Ambient Noise
PomoNoise combines a clean Pomodoro timer with a powerful ambient noise mixer to help you focus, study, and get more done. Choose from six noise colors — white, pink, brown, green, blue, and violet — and mix them at any volume to create your perfect focus soundtrack. The built-in Pomodoro timer keeps your work sessions structured with 25-minute focused intervals followed by short breaks.
Brown noise has become one of the most popular focus tools, especially within the ADHD community, where its deep, steady rumble helps quiet distracting thoughts and improve concentration. Unlike music or podcasts, noise colors provide a consistent audio backdrop that doesn't compete for your attention.
PomoNoise is designed for students, remote workers, writers, developers, and anyone who needs to concentrate. It works entirely in your browser with no downloads, no signup, and no usage limits. Every sound is generated in real time using the Web Audio API — no looped audio files, no buffering, just pure, infinite noise at the quality you choose.
Use PomoNoise to power through study sessions, tackle deep work, or simply create a calm environment for reading and thinking. Combine multiple noise colors to find the mix that works best for you, and let the Pomodoro timer handle the rest.
Frequently Asked Questions
What is the Pomodoro Technique?
The Pomodoro Technique is a time management method where you work in focused 25-minute intervals (called pomodoros) followed by 5-minute short breaks. After completing four pomodoros, you take a longer 15-minute break. This cycle helps maintain concentration and prevents burnout.
Why combine a Pomodoro timer with ambient noise?
Research shows that consistent background noise like brown noise or rain sounds can improve focus by masking distracting sounds. Combining this with timed work sessions creates an ideal environment for deep work, studying, or any task that requires sustained attention.
What is brown noise and why is it popular for focus?
Brown noise is a deep, rumbling sound with more energy at lower frequencies than white noise. It has gained popularity especially among the ADHD community for its ability to help with concentration and focus. Unlike white noise which sounds like static, brown noise sounds more like a steady waterfall or strong wind.
Is PomoNoise completely free?
Yes. PomoNoise is 100% free with no signup required, no account needed, and no usage limits. All noise colors and the Pomodoro timer are available without any restrictions.
What noise colors are available?
PomoNoise offers six noise colors: white noise (equal energy across all frequencies), pink noise (balanced, natural-sounding), brown noise (deep, low-frequency rumble), green noise (mid-range, calming), blue noise (bright, high-frequency), and violet noise (very bright, sharp high frequencies). You can play multiple noise colors simultaneously and adjust each volume independently.
