時間制限付き集中セッションを使う理由は？
Conquer the 2-minute rule
David Allen's GTD method says: if a task takes less than 2 minutes, do it now. A 1-minute timer gives you a crisp boundary — you either finish the task or realize it's bigger than you thought.
Break the procrastination loop
The hardest part of any task is starting. Committing to just one minute removes the psychological resistance. You can always stop after one minute — but you rarely want to.
Micro-recovery between deep work blocks
One minute of deliberate breathing or stretching resets your nervous system more effectively than a passive scroll break. Use this timer as a structured micro-rest.
このタイマーを使う場面
The 1-minute timer works best for immediate micro-tasks: replying to a short message, filing a document, wiping down your desk, or doing a quick gratitude check. It is also the ideal timer for guided breathing exercises like box breathing (4-4-4-4 counts).
よくある質問
What is a 1-minute timer good for?+
A 1-minute timer is ideal for micro-tasks (the GTD '2-minute rule'), short breathing exercises, timed flashcard reviews, or as the first step in overcoming procrastination by committing to 'just one minute' of a bigger task.
Can I use this timer without installing anything?+
Yes. This is a browser-based countdown timer — no app, no download, no sign-up. Press play and it runs. Your browser plays a soft chime when the minute is up.
What happens when the timer ends?+
The ring fills completely, the display shows 'Done!', and you hear a short audio tone. You can immediately reset and start again.
