Useful results, without the extra work
A lap measures the time since the previous lap; the total split measures the time since you started. Pause for a break, then resume the same session. Copy a readable results table or export a CSV file when you are finished.
All controls work with the keyboard. Optional shortcuts can be enabled above: Space to start or pause and L to record a lap, when you are not typing or using another control. Active timing uses a monotonic clock. After a refresh, elapsed time is recovered from your device clock, so changing the device clock can affect recovery. Keep the page open for dependable session timing.
