Online Stopwatch
Track time accurately. Perfect for running, cooking, workouts.
Common Uses
🏃 Running: Track mile splits. Hit "Lap" at each mile to see your pace.
👨🍳 Cooking: Time pasta (11 min), eggs (6.5 min boiled), steak rest (5 min).
💪 Workouts: HIIT intervals (30s work, 10s rest). Plank challenges.
📚 Study: Pomodoro (25 min focus, 5 min break).
💡 Expert Tip: Using Laps
Don't just stop the timer! Use the Lap button to track intervals without pausing the total time. This is crucial for runners tracking mile splits or HIIT workouts where you need to see consistency.
⚠️ Common Mistake: Relying on Browser Tabs
Browsers often "throttle" (slow down) inactive tabs to save battery. If you switch tabs, the timer might drift. For critical timing, keep this tab active or open in a separate window.
