Pomodoro Timer — Free, No Ads, No Account

The Pomodoro Technique

Work for 25 minutes, rest for 5. Repeat four times, then take a 15-minute long break. The method was developed by Francesco Cirillo in the 1980s (the kitchen timer he used was shaped like a tomato — pomodoro in Italian). Decades of research on spaced rest back the core idea: short, regular breaks prevent cognitive fatigue and sustain attention across long work sessions far better than grinding through without stopping.

Why ambient sound helps

Moderate ambient noise (~70 dB) has been shown to improve creative performance and maintain focus by masking disruptive background sounds. Rain, café chatter, and white noise all produce similar effects — the “right” choice is whichever you find least distracting. All three are generated in real time by the Web Audio API; nothing is downloaded.

Tips for getting started

• Before each session, name the task you're working on — it reduces decision fatigue mid-session.
• Treat the break as mandatory, not optional. Close the tab, stand up, look away from the screen.
• If you finish before the timer, use the time to review what you just did — not to start the next thing.
• 4 pomodoros = roughly 2 focused hours. That's a realistic daily target for deep work.
