What this page is

Simple Stopwatch is a fast, private, browser-based stopwatch for everyday tasks—study sessions, workouts, talks, cooking, and productivity sprints. It runs locally on your device (no sign-in) and supports keyboard shortcuts, dark mode, and lap times.

Start the timer, add laps to capture splits, pause to take a break, then resume without losing precision. Below you’ll find quick tips, a shortcut cheat-sheet, and answers to common questions.

How to use Simple Stopwatch

Simple Stopwatch is a minimal stopwatch that prioritizes accuracy, accessibility, and speed. Hit Start (or press Space) to begin timing. Use Lap to capture split times without stopping the clock. Press Pause to freeze the timer, then hit Start again to resume from where you left off. Reset clears the clock and laps.

This tool runs entirely in your browser—no sign‑in, no tracking cookies for features, and nothing is sent to a server. It works well for workout intervals, talks, cooking, speed‑runs, or any task where you want a precise and distraction‑free stopwatch.

Prefer a darker look? Toggle the moon/sun button in the header to switch between light and dark modes. Your choice is saved on this device.

Keyboard shortcuts

Keep your hands on the keyboard while you time:

  • Space: Start/Pause
  • L: Add lap
  • R: Reset
  • C: Copy current time

Tips for accuracy

The stopwatch uses high‑resolution time sources in modern browsers and updates the display up to 60 times per second. For the most consistent results, keep this tab active. If you switch tabs for a long time, the page keeps time accurately and catches up when you return, but the visual update rate may be reduced by the browser in background.

Practical ways to use this timer

Here are simple, real-world workflows you can copy:

  • Pomodoro focus (25/5): Work for 25 minutes, press L to mark the end, take a 5-minute break, then repeat. After four cycles, take a longer 15–20 minute break.
  • Workout intervals: Start the timer, hit L at each set or lap. The lap table tracks each split so you can compare pace or rest consistency.
  • Speech practice: Rehearse from start to finish and press L at each section (intro, body, close). Check total time and per-section timing to tighten your delivery.
  • Cooking: For multi-step recipes, press L at each step boundary to keep a record of how long stages actually take on your stove/oven.
  • Deep work sprints: Use 45–60 minute focus blocks with short breaks. The lap list shows how many blocks you actually completed today.

Tip: You can copy the current time with C and paste it into notes or a spreadsheet.

FAQ

Is the timer accurate enough for speed‑critical tasks?

Yes—elapsed time is based on a monotonic clock (not system wall time), which prevents jumps if your system clock changes. Display granularity is 1 ms.

Does it work offline?

Yes, after the page is loaded. Everything runs in your browser.

Can I export or copy lap times?

Use the Copy button to copy the current time. You can also select the lap table and copy it into a spreadsheet.

What about privacy?

The timer itself stores only your theme preference locally on this device. We avoid analytics by default here; ad slots may load via Google AdSense—see their privacy documentation for details.

Privacy & accessibility

We keep things simple: no login, no account, and no personal data collection for timer features. The timer readout is announced to assistive tech using an aria‑live region. Buttons have visible focus states and sensible labels.
