How to use
- Press “Start” or the Space bar to begin, and press again to pause.
- While it runs, press “Lap” or L to record the split for that lap and the total time so far. With two or more laps, the fastest is shown in green and the slowest in red.
- Use “Copy” to copy the lap table as tab-separated text that pastes neatly into Excel or Google Sheets.
- After pausing, press “Reset” or R to go back to zero.
FAQ
How precise is it?
The display shows hundredths of a second and the lap table shows milliseconds. Time is calculated from your device clock, so it stays right even if you switch tabs or the screen dims — your own reaction time is the main source of error.
What is the difference between lap and total time?
Lap time is how long that lap took since the previous one. Total time is everything since you first pressed Start.
Are my laps saved?
No. Laps live only on this page and disappear when you reload it. Use “Copy” to keep them.
