無料オンラインポモドーロタイマー

Developed by Francesco Cirillo in the late 1980s, the Pomodoro Technique is a time management method: work for 25 minutes (one "pomodoro"), take a 5-minute break, and repeat. After 4 pomodoros, take a 15–30 minute long break. The name comes from a tomato-shaped kitchen timer.

It leverages focused work intervals to minimize distractions, uses regular breaks to prevent cognitive fatigue, creates urgency (25 minutes feels finite and manageable), and gamifies task completion through pomodoro counting.

Yes. Go to Settings to change work interval (default 25 min), short break (default 5 min), and long break (default 15–30 min). Common variations: 45/15, 52/17, or 90/20 minute work/break ratios.

Short breaks (5 min): stand up, stretch, look away from the screen (20-20-20 rule), get water. Long breaks (15-30 min): walk, eat, do light physical activity. Avoid checking social media or email — the break is for your brain, not your inbox.

Yes. The JavaScript timer continues running in the background. When the session ends, an audio alert plays and you receive a browser notification (if notifications are enabled).
