How to use this tool
- Start timer and capture laps during active run.

- Export lap logs and summary report for session records.
Precision
- Stopwatch uses performance timing with animation-frame updates.
- Lap deltas isolate segment duration independent of total elapsed.
- Target progress bar helps pacing in fixed-session workflows.
Operational usage
- Use keyboard shortcuts when timing while coding or training.
- CSV exports integrate with spreadsheets and QA logs.
- JSON reports preserve all lap metadata for audits.
FAQ
- Does it run when tab is backgrounded?
- Elapsed time is based on timestamps, so totals remain consistent when resumed.
- Can I export only the latest lap?
- Current export includes all laps; filter in CSV if needed.
- Is there an audible alert at target?
- No. Target state is visual only in this version.
