A stopwatch that does not lose time
Most browser stopwatches count ticks — they ask the browser to nudge them roughly every so often and add up the nudges. That works until you switch tabs, at which point the browser deliberately slows those nudges down to save battery, and the stopwatch quietly falls behind.
This one records the exact moment you pressed start and works out the difference against the current time whenever it redraws. Switching tabs, minimising the window or locking your phone makes no difference to the result. Come back an hour later and the elapsed time is correct, not an hour of missed ticks short.
Laps and splits
Press Lap while it runs to record a split without stopping the clock. Each row shows the time for that individual lap next to the running total, so you can see whether you are speeding up or slowing down rather than doing the subtraction yourself. Once there is more than one lap the fastest and slowest are highlighted automatically.
Made for leaving open
- Space starts and stops, L records a lap — no need to find the buttons.
- Full screen scales the digits to fill the display, hides every ad, and fades the header away.
- Hundredths of a second are shown throughout, in your choice of six numeral fonts.
- Tabular digits mean the numbers never jitter sideways as they change.
Common uses are interval training, timing presentations and exams, cooking, lab work, and timing how long a task actually takes. If you want to count down to zero rather than up from it, use the timer instead.
