About the Stopwatch With Export

When lap lists need to live in a spreadsheet, a coach email, or a lab notebook, retyping splits is where errors creep in. A stopwatch with export sends session data - lap index, split, cumulative total, optional notes - to a CSV file you open in Excel, Google Sheets, or R without hand transcription. Researchers timing repeated trials get one row per lap per run. Swim coaches attach exports to weekly reports.

How to use it

  1. Complete the session with disciplined lap marking.
  2. Review the on-screen lap list for a missing final lap.
  3. Choose Export and save the CSV with a dated filename.
  4. Open in your spreadsheet and verify row count matches laps.
  5. Archive or merge into your master log or control chart.

Good to know

The stopwatch counts while this tab is open. A slept tab can pause or jump. For a race result you may need to keep the phone unlocked in your hand.
