This stopwatch counts upward from zero so you can measure how long an activity, attempt, task, or interval takes. It includes start, pause, reset, and lap controls.
Use lap times when one continuous activity has smaller sections inside it, such as practice rounds, exercise sets, rehearsal passes, speed tests, or repeated work cycles.
Use the stopwatch when you do not know the final duration in advance. It is designed for measuring how long a task, activity, attempt, or interval actually takes.
Lap times are useful when one continuous activity has smaller sections inside it. You might record laps for practice rounds, exercise sets, rehearsal passes, study cycles, support calls, speed tests, or any repeated task where each split matters.
Record laps for drills, rounds, sets, or repeated attempts where each split matters.
Measure how long support calls, admin tasks, edits, tests, or repeatable workflows actually take.
Compare attempts over time by saving lap marks at consistent checkpoints.
Use the stopwatch when you need to observe duration rather than enforce a deadline.
Choose the timer when the duration is known before you start. A countdown is best for deadlines, reminders, focus blocks, cooking times, break limits, and routines where the end point matters.
Choose the stopwatch when the duration is the thing you want to measure. A stopwatch is best for tracking attempts, comparing laps, recording task length, timing an activity, or understanding how long a process really takes.
Yes. Use the custom hours, minutes, and seconds fields, then set the timer before starting the countdown. The selected custom duration becomes the timer's reset point.
A timer counts down from a set amount of time to zero. A stopwatch counts up from zero so you can measure how long something takes.
Yes. Start the stopwatch and use the lap control to save recent split times while the elapsed time continues.
The timer uses timestamps rather than simply counting browser ticks, so it corrects itself when the tab resumes or the browser throttles background updates.
Yes. The countdown plays a short browser-generated chime when it reaches zero. Your browser, device, or operating system volume settings can affect whether you hear it.
Yes. Both tools can be paused and resumed. Reset returns the timer to its selected duration and clears the stopwatch back to zero.
