High-Precision Timer • Lap Recording • CSV/Excel Export
This is a precise stopwatch for timing anything — workouts, races, experiments, cooking, or any task with multiple stages. Press Lap while it's running to record a split, showing both the time for that specific lap and the running total. Timing is calculated from real timestamps rather than simply counting up on an interval, so it stays accurate even if the browser tab is briefly backgrounded. When you're done, export all your recorded laps as a CSV file, which opens directly in Excel, Google Sheets, or any spreadsheet program. All processing happens locally in your browser.
