Online Stopwatch with Laps
Start, pause and record laps with a large live display. Review lap count, latest, best and average lap in the result area, then copy or export the session.
Stopwatch workspace
The result area is live from the moment you start. Record laps without interrupting the stopwatch, then compare latest, best and average lap times.
Keyboard: Space = start/pause · L = lap · R = reset when paused
Timing method: elapsed time is derived from timestamps rather than incrementing a counter on every screen refresh. This helps avoid accumulated drift when rendering slows.
Full Screen Stopwatch with Lap Tracking
Select Full Screen above the online stopwatch for a larger elapsed-time display. This helps when timing presentations, exercise intervals, classroom activities or practice sessions where you need to read the clock from a distance.
The Start, Pause, Lap and Reset controls work in the focused view, and your recorded laps are not cleared simply by entering or exiting full screen. Use Exit Full Screen to return to the page, where you can copy or export your lap results as CSV.
Stopwatch with a Useful Result Area
The result panel is no longer an empty calculator placeholder. It now acts as the stopwatch's live lap workspace. Each lap records an individual lap duration and the total elapsed time at that point. Summary cards show how many laps you have recorded, the latest lap, the fastest lap and the average lap.
The stopwatch display uses hundredths of a second for convenient on-screen timing. For ordinary browser use this is useful for work sessions, study intervals, exercise sets, presentations, production checks and informal performance measurements. It is not a certified sports timing instrument.
Copy or Export Lap Results
When a session is finished, Copy Results puts the elapsed time and lap list on the clipboard. Download CSV creates a simple file with lap number, lap time and total time, which is convenient for spreadsheets or records. These operations happen locally on your device.
Example: if you record laps at 00:45.20, 01:29.80 and 02:16.10 total elapsed time, the result area also calculates the individual lap intervals so you can compare pace rather than only cumulative time.
Stopwatch Controls
- Start / Pause: start timing or freeze the current elapsed time without clearing it.
- Lap: capture the current interval while the main stopwatch continues running.
- Reset: clear elapsed time and laps after the stopwatch has been paused.
- Keyboard shortcuts: Space starts or pauses, L records a lap, and R resets while paused.

Yes. Select Full Screen above the stopwatch, then use Lap as usual. Your elapsed time and recorded laps remain available when you exit full screen.
Where are the stopwatch results?
The complete live result area is beside the stopwatch on desktop and directly below it on smaller screens. It shows lap statistics and every recorded lap.
Can I export laps?
Yes. Use Download CSV to save lap number, individual lap time and cumulative elapsed time.
Does pausing erase laps?
No. Pause keeps the elapsed time and lap history. Reset clears the session.
Is the stopwatch suitable for official race timing?
No. It is a browser-based convenience tool and can be affected by the device, operating system and browser environment.
