Pomodoro Timer

Developed by Francesco Cirillo in the late 1980s, the Pomodoro Technique divides work into 25-minute focused intervals (called pomodoros) separated by 5-minute breaks. After completing four pomodoros, you take a longer 15-30 minute break. The technique works because 25 minutes is long enough to make meaningful progress but short enough to maintain intense focus — research shows that sustained attention typically deteriorates after 20-30 minutes without a break. During each pomodoro, you work on a single task with zero interruptions: no checking email, no responding to messages, no switching tasks. If an interruption occurs, you either postpone it (write it down and address it after the timer) or abandon the pomodoro and start fresh. This discipline builds the habit of deep work. Most people complete 8-12 pomodoros per productive day, representing 3.3-5 hours of concentrated work — more focused output than most 8-hour workdays produce. This timer automates the cycle with configurable work and break durations, tracking your completed pomodoros throughout the day.

While the classic 25/5 split works well for most people, the optimal intervals depend on your work type and concentration capacity. Software developers often prefer 50-minute focus periods because entering a coding flow state takes 10-15 minutes, and breaking at 25 minutes disrupts it. Writers might use 45-minute sessions. For tedious administrative tasks, shorter 15-minute bursts can prevent procrastination. Experiment to find your ideal ratio — the key principle is alternating focused work with genuine rest. During breaks, stand up, stretch, look at something distant (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds), and avoid screens. Your brain consolidates information during rest periods, which is why solutions to difficult problems often appear during breaks. Track your pomodoros over a week to understand your productivity patterns: most people have peak focus in the morning (9-11 AM) with a secondary peak in the late afternoon (3-5 PM). Schedule your most demanding tasks during these windows and save routine work for low-energy periods.
