The GTD 2-minute rule, made visual
Getting Things Done author David Allen advises completing any task that takes 2 minutes or less immediately rather than scheduling it. This timer makes that rule tangible and satisfying.
Quick email and message replies
Most short email replies take under 90 seconds to write. Setting a 2-minute timer creates a small deadline that sharpens your focus and stops you from over-editing simple responses.
A mindful reset between context switches
Two minutes of eyes-closed breathing or stillness is enough to clear working memory after a demanding task. This timer structures those transitions so they don't stretch into 20-minute distractions.
このタイマーを使う場面
Use a 2-minute timer for quick captures (writing a thought into your task list), fast file organization, standing up between desk sessions, or timed journaling prompts. Pairs perfectly with a Pomodoro break routine.
よくある質問
What is the GTD 2-minute rule?+
Productivity expert David Allen's rule: if a task will take 2 minutes or less to complete, do it immediately instead of adding it to a to-do list. The 2-minute timer makes this rule concrete by giving you a visual countdown.
Is 2 minutes enough to make a meaningful break?+
Yes — research on attention restoration shows that even very short mental breaks reduce cognitive fatigue. Two minutes of focused breathing activates the parasympathetic nervous system, providing measurable recovery.
Can I chain multiple 2-minute timers?+
Absolutely. Many productivity practitioners use repeated micro-sprints: 2 minutes on a task, 1 minute reset, repeat. Simply press reset and play when the chime sounds.
