How do I use an online stopwatch with laps?
Press Start to begin timing and Lap each time a lap or split ends. Each lap shows its own time and the running total, with the fastest and slowest laps marked. Press Stop to pause, Resume to continue and Reset to clear. FixDoks's Stopwatch runs in your browser, shows hundredths of a second, and lets you copy laps or download them as CSV.

A stopwatch in your browser
This stopwatch counts up from zero with hundredths of a second, records as many laps as you need and works on phones, tablets and computers. It is useful whenever you need to know how long something took rather than count down to a set time.
Laps and split times
Each time you press Lap, the stopwatch records two figures:
- Lap time: the time since the previous lap. Use it to compare laps of a track, lengths of a pool or repetitions of a task.
- Total: the time since you pressed Start, often called the split.
Once there are two or more laps, the fastest is shown in green and the slowest in red, so you can see at a glance where you slowed down. The current lap keeps counting under the main display.
Keeping your results
Copy laps puts a plain text list on your clipboard, ready to paste into a message or notes. Download CSV saves a file with each lap time and total, in both minutes:seconds format and seconds, which opens in Excel or Google Sheets for charts and averages.
Accuracy
The stopwatch uses your browser's high-resolution clock, so it does not drift if the display updates slowly. The display updates many times a second while running. In a background tab the display pauses to save power, but the time is still counted correctly and shows again when you come back.
Uses
- Running, cycling and swimming laps, and interval training.
- Timing a speech, a reading or a practice answer.
- Measuring how long a task or process takes at work.
- Science experiments and classroom activities.
- Board games and quizzes where each turn is timed.
To count down from a set time instead, use the online timer.
