Lap timing with export-ready results
Use this stopwatch when you need continuous elapsed time plus lap splits you can review later. It supports precision changes, lap history, fullscreen display, and CSV/JSON export, so it works for drills, practice logs, and timing checks. Hidden tabs may refresh less often visually, but the measured elapsed time keeps running.
Best-fit uses
- Capture lap splits during training or process checks.
- Export CSV or JSON after a run for notes or spreadsheets.
- Copy a TSV lap table when you only need plain text results.
What to remember
- Shared URLs keep display settings, not the live running state.
- Browser refresh or device change is not the same as a dedicated timing instrument.
- Verify the selected precision before comparing runs across teams.
FAQ
Will the timer drift?
Display updates may throttle under heavy load, but the timing itself is measured with a high-precision timer.
Does the share URL include the running state?
No. Only display settings are shared. The running state and lap data are not included.
Can I export lap history?
Yes. Export laps as CSV or JSON, or copy a TSV table for notes and spreadsheets.
Does the stopwatch keep lap data after refresh?
If save-laps is enabled, the same device can restore recent lap data locally. Shared URLs do not include live lap history.
