A timer, stopwatch and Pomodoro — all in one
This single tool combines the three timing tools you reach for most: a countdown timer for cooking, workouts and reminders; a stopwatch to measure how long something takes; and a Pomodoro focus timer for structured work sessions. No app to install, no account to create — keep the tab open and it just works.
How it works
All three modes are driven by real elapsed wall-clock time rather than a tick counter, so they stay accurate even when the browser throttles a background tab. The timer counts down from the minutes and seconds you set to zero; the stopwatch counts up from zero; and Pomodoro runs the classic 25-minute focus / 5-minute break cycle, switching automatically and tallying how many focus blocks you complete. When a countdown reaches zero — or a Pomodoro phase ends — a short beep is generated on the fly with the Web Audio API, so no sound file is loaded.
Mode comparison
| Mode | Direction | Best for |
|---|---|---|
| Timer | Counts down | Cooking, reminders, intervals |
| Stopwatch | Counts up | Timing tasks, laps |
| Pomodoro | 25 / 5 cycles | Focused work sessions |
Worked examples
Tea or pasta timing. Set the timer to 4:00 and press Start. Walk away — when the kettle is ready the beep fires even if you have switched to another tab, because timing tracks wall-clock time, not tab activity.
Lap timing with a stopwatch. Press Start when the interval begins, then Lap after each segment. Each lap split is recorded independently so you can compare them at the end without losing the running total.
A Pomodoro work session. Switch to Pomodoro mode and press Start. The tool runs 25 minutes of focus, beeps, then starts a 5-minute break automatically. After four focus cycles many practitioners take a longer 15–20-minute break. The completed-cycle count shown in the tool is the signal to pause and step away properly.
The Pomodoro technique in practice
The Pomodoro technique was developed to help people resist interruptions and maintain consistent effort. The core idea is that most people can concentrate fully for 25 minutes; shorter sprints feel achievable and create a rhythm that keeps momentum through a long day. The automatic transition in this tool removes the need to watch a clock, so you can stay in flow during the work block and properly disconnect during the break.
Common adjustments people make:
- Longer work blocks — some prefer 45/15 or 50/10 splits for deeper work
- Shorter blocks — 15/5 suits people new to the technique or doing repetitive tasks
- Counting cycles before a long break — four 25-minute blocks followed by a 20-minute rest is a common pattern
This tool uses the classic 25/5 split with automatic switching. The cycle counter keeps a running tally so you know exactly how much concentrated work you have done in a session.
Practical tips
- Leave the tab open, not the window minimised. Modern browsers throttle background tabs more aggressively than background windows; keeping the timer visible prevents any throttling from affecting the display refresh.
- Allow audio if your browser asks: the beep uses the Web Audio API, so you may need to interact with the page once before it can play sound. The first time you press Start the permission is granted.
- Stopwatch laps are useful for interval workouts, reading sprints, or any activity where you want to track splits rather than a single elapsed time.
- No data ever leaves your browser — there is no account, no sync, and nothing is stored between sessions.
