A clean, distraction-free stopwatch with lap timer. No ads, no account, no install. Start measuring in one click on any device.
Track pace per lap, circuit time, or total run duration. Lap button records each split while the overall clock runs.
Time individual lengths or sets. Each lap press records the interval so you can review consistency across the session.
Measure exact cook times without a preset duration. Useful when a recipe says "cook until golden" rather than a fixed time.
The ring on this stopwatch fills over a 60-second cycle — each full rotation represents one minute elapsed. It resets at 60 seconds and begins again, so you always have a visual reading of your current minute's progress.
Full lap timing and keyboard shortcuts built in.
Click Start or press Space. The clock begins counting from 0:00.0 immediately.
Press Lap or the L key to record a split. The lap time and cumulative time are listed below the ring.
Press Space or click Start again to pause. Press Space to resume from the paused time.
Press R or click Reset to clear the timer and all lap records instantly.
This stopwatch uses wall clock time (Date.now()) for elapsed calculation, which is accurate to millisecond precision on modern devices. For professional timing events, a certified stopwatch is required. For workouts, cooking, and everyday use, this is more than accurate enough.
A lap timer records split times — the time elapsed at each point you press Lap. You can see how long each interval took while the overall stopwatch keeps running. Useful for running circuits, swimming sets, and interval training where you want to compare individual round times.
A stopwatch counts up from zero — you start it and it measures elapsed time. A countdown timer counts down from a set duration and alarms at zero. Use a stopwatch when you don't know the target time; use a countdown timer when you have a specific target duration in mind.
Yes. The stopwatch continues running in the background when you switch browser tabs. The elapsed time uses wall clock time rather than animation frame counting, so it stays accurate even when the tab is not in focus.
Press Start when your work interval begins. Press Lap when it ends to record the split. Press Lap again when your rest ends to record the rest duration. Each press adds a row to the lap list so you can review consistency across all rounds after your session.
Yes. This stopwatch is fully responsive and works on all screen sizes. On mobile, tap the buttons normally. The ring and display scale to fit smaller screens automatically.
Running and swimming pace tracking, HIIT and circuit training, cooking and food preparation, classroom and exam timing, sports coaching drills, speech rehearsal, board game turn timers, and measuring task completion time for productivity analysis.
A browser-based stopwatch has specific advantages for sport and training.
This stopwatch uses wall clock time (Date.now()) for elapsed calculation rather than counting animation frames — meaning it stays accurate even when your browser tab is in the background, your phone screen dims, or your device throttles background processes. The lap list records every split automatically, with cumulative time displayed alongside each lap time for pace analysis.
Start at the beginning of your run, press Lap at each kilometre or mile marker. Review your split times after to analyse pace consistency.
Time individual drill repetitions. Press Lap after each rep to record times without stopping the overall clock — exactly how coach timing works.
When a recipe says "cook until golden," use a stopwatch to track your actual cook time so you can replicate the result next time.
