Questions and answers

Does it keep timing if I switch tabs?
Yes. The stopwatch is built on absolute epoch time (Date.now()), so switching tabs or returning after a browser pause does not add tick-count drift. The elapsed time is recalculated from the real clock when the page updates.
How do I record a lap?
Click the Lap button while the stopwatch is running, or press the L key. Each lap entry shows the split (time since the last lap) and the running total. The most recent lap is highlighted at the top of the list.
Can I save my lap times?
Yes. Click "CSV" after recording at least one lap to download stopwatch-laps.csv, or click "Copy" to place the lap/split table on your clipboard.

About this stopwatch

The Clockfresh stopwatch is a free, ad-free browser stopwatch with laps, a copyable lap table, CSV export, fullscreen mode and keyboard shortcuts. Hit Start to begin, Lap to mark splits, and Stop to pause. The elapsed time is computed from the real system clock — not accumulated tick counts — so it catches up cleanly when the page updates after tab switches or browser pauses. Use fullscreen for a big classroom display, and copy or export your laps for further analysis in a spreadsheet.

Common uses

  • Athletics and fitness — track intervals, splits and personal bests.
  • Cooking — time multiple stages without resetting between them.
  • Presentations and debates — keep speakers to their allotted time.
  • Development and testing — measure how long a build or process takes.
  • Games — any activity that needs a running clock with recorded splits.
