Timer & Stopwatch

A free online countdown timer and stopwatch with lap times, alarm sound and Pomodoro presets. Runs in your browser, nothing to install.

The Timer & Stopwatch combines a countdown timer with an alarm, a lap-tracking stopwatch, and Pomodoro presets in one browser tool — no app install, no ads interrupting a focus session. Set a countdown for a specific task, switch to the stopwatch to record lap splits, or use a Pomodoro preset to structure work into focused intervals with built-in breaks.

Elapsed and remaining time are calculated from timestamps rather than a simple tick counter, so switching tabs or letting your laptop sleep briefly doesn't cause the timer to drift out of sync. Whether you're timing a workout, running a classroom activity, or working through a Pomodoro session, the tool keeps accurate time in the background while you focus on the task.

How to use the Timer & Stopwatch

1. Choose between Timer, Stopwatch or Pomodoro mode.
2. For the timer, set the countdown duration and start it — an alarm sounds when it reaches zero.
3. For the stopwatch, press start and tap Lap to record split times as you go.
4. Review your recorded lap times listed in order once you stop the stopwatch.
5. For Pomodoro, select a work/break preset and let the tool cycle through focus and rest intervals automatically.

Why use this tool

Accurate even in background tabs

Time is calculated from timestamps rather than tick counts, so the countdown or stopwatch never drifts even if the tab loses focus.

Three tools in one

Switch between a countdown timer, a lap stopwatch and Pomodoro presets without needing three separate apps.

Audible alarm on completion

A sound plays when a countdown reaches zero, so you don't need to keep glancing at the screen while working on something else.

Common use cases

• Running Pomodoro focus sessions with built-in work and break intervals.
• Timing a workout circuit with a countdown and alarm between exercises.
• Recording lap splits for a practice run or timed drill.
• Setting a countdown for a classroom activity or exam section.
• Timing cooking steps that need a precise countdown with an alert.

Why timestamps matter for accuracy

Simple tick-based timers can lose time if the browser throttles background tabs, a common behaviour used to save battery. Calculating elapsed time from the difference between two timestamps avoids that drift entirely, so the timer stays accurate even minimised.

Using Pomodoro presets

The Pomodoro technique splits work into focused intervals — typically 25 minutes — followed by a short break, with a longer break after several cycles. The presets handle the switching automatically so you can stay in the work session without resetting a timer manually.

Lap timing accuracy

Each lap records the exact time since the previous lap and the total elapsed time, useful for comparing split consistency across repeated efforts like interval training or timed reading exercises.

Frequently asked questions

Does the timer keep running in a background tab?

Yes. Elapsed time is calculated from timestamps rather than tick counts, so switching tabs never causes drift.

What is the Pomodoro technique?

Work for 25 focused minutes, take a 5-minute break, and after four rounds take a longer 15–30 minute break — a simple rhythm that protects concentration.

Is Timer & Stopwatch free to use?

Yes. Timer & Stopwatch on Klipza is completely free with no account, no subscription and no watermark on your files, and there is no daily usage limit.
