Frequently Asked Questions 常见问题

• What is the Pomodoro Technique? — The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It uses a kitchen timer to break work into intervals (typically 25 minutes) separated by short breaks, improving focus and productivity.
• Why 25 minutes? — 25 minutes is the traditional interval, but you can adjust it. Some people prefer 50/10, 90/20, or other ratios. The key is finding an interval that keeps you focused without causing fatigue.
• Does the timer work in the background? — Yes, the timer continues running even if you switch to another tab. When the session ends, the notification sound will play (note: browser tab must be open for sound to work).

• 什么是番茄工作法？ — 番茄工作法是 Francesco Cirillo 在 1980 年代末开发的时间管理方法。用计时器将工作分成若干时段（通常 25 分钟），中间用短休息隔开，提高专注力和效率。
• 为什么是 25 分钟？ — 25 分钟是传统的间隔时间，但你可以自行调整。有些人偏好 50/10、90/20 等比例。关键是找到一个让你保持专注而不疲劳的间隔。
• 计时器在后台运行吗？ — 是的，即使切换到其他标签页计时器也会继续运行。会话结束时播放提示音（注意：浏览器标签页必须保持打开才能发出声音）。
