タイマー＆ストップウォッチとは？
The Timer provides countdown timer, stopwatch, and alarm functionality in a clean, easy-to-use interface. Whether you're timing a workout, cooking, studying with the Pomodoro technique, or tracking any time-sensitive activity, this tool has you covered. Effective time management is consistently linked to higher productivity and lower stress. Techniques like the Pomodoro method (25-minute focused work intervals with 5-minute breaks) and time-boxing rely on accurate timers to structure work sessions. This timer works entirely in your browser with audio notifications, so you don't need to install any app. Set custom durations, use preset intervals for popular techniques, or use the stopwatch for open-ended timing. The timer continues running even when you switch to other browser tabs.

よくある質問
▶ストップウォッチはどれくらい正確ですか？
ストップウォッチはブラウザの高解像度タイマーを使用し、ミリ秒の精度を提供します。
▶タブを切り替えてもタイマーは動作しますか？
はい！タブを切り替えてもタイマーは実行し続けます。カウントダウンがゼロになるとアラート音が鳴ります。
▶ラップタイムを記録できますか？
はい！ストップウォッチモードでラップボタンを押すとスプリットタイムが記録されます。すべてのラップは個別時間と累積時間で表示されます。
▶Will the timer keep running if I switch tabs?
Yes. The timer uses background-safe timing mechanisms that continue accurately even when the tab is not active. You'll receive an audio notification when the timer completes.
▶What is the Pomodoro technique?
The Pomodoro technique is a time management method where you work in focused 25-minute intervals (called 'pomodoros') separated by 5-minute breaks. After four pomodoros, you take a longer 15-30 minute break. It's proven to improve focus and reduce mental fatigue.
▶Can I set multiple timers at once?
The current version supports one active timer at a time. For multiple concurrent timers, you can open the tool in multiple browser tabs, each running an independent timer.
