How to use the race finish stopwatch
Enter one participant or bib number per line and prepare the lineup. Start the race clock once. Tap a participant's Finish button as they cross the line; their time is recorded without stopping the others.
Finish order is based on captured times, with tap order breaking exact ties. Gaps compare each result to the first finish. Undo latest finish restores that participant's button. The race ends automatically when everyone finishes; you can end it early and unfinished entries are exported as Not recorded.
Can I use this for official race results?
This is a manual practice and small-event recorder. Human reaction, device input latency and browser scheduling affect the result; it is not certified electronic timing. Keep one operator and one page for a shared start.
How accurate is the stopwatch?
The display can show hundredths of a second, but human reaction and browser input latency affect a manual measurement. Live timing uses a monotonic clock, so changing the device time does not change an open session. After a refresh, recovery uses saved device timestamps. Device sleep and a changed clock can affect that recovery. Keep this page and device awake for dependable timing.
Where are my results saved?
Only in this browser on this device, with no account required. Use one tab per tool to avoid overwriting the same saved session. Export CSV before clearing local settings. Each session can hold up to 500 marks and seven days of active elapsed time. Live updates stop while paused; no stopwatch readings are sent to our server.
