Choose lap analysis for repeatable efforts, running or swimming for distance-aware splits, a race recorder for shared starts, or independent watches for simultaneous activities. Task and time-study stopwatches help turn elapsed time into understandable records.
Does a stopwatch need internet time?
No. A stopwatch measures a duration, not the current time of day. These tools use a monotonic browser clock while open. No request is sent to a time server for each update. Refresh recovery uses saved device timestamps, so changing the device clock can affect restored results.
Do I need an account to save results?
No. Current sessions stay in this browser. Copy or export your results before clearing data or switching devices. A browser stopwatch is useful for practice and everyday measurements; its display precision is not a guarantee of measurement accuracy.
