Timer, Stopwatch & Pomodoro

This page puts three timers in one place. The Timer tab counts down from a quick time such as 5 or 25 minutes, or from any hours, minutes and seconds you type, and finishes with a soft chime. The Stopwatch tab counts in hundredths of a second and records laps. The Pomodoro tab runs the well-known focus method: work for 25 minutes, take a 5-minute break, and after four rounds take a longer one, with every length up to you.

Most free timers count ticks, so they drift or freeze when you switch tabs or your laptop sleeps. This one works from the real clock: it notes when the time will end and checks against that, so 25 minutes is 25 minutes even if the tab sat in the background. The time left shows in the tab title, the chime is booked on the audio clock so it rings on time, and you can ask for a notification too.

Use it for study, cooking, workouts and exams. Everything runs in your browser: your settings, tasks and daily count are kept on this device only, and nothing is sent anywhere.

1. Pick a tab at the top: “Timer”, “Stopwatch” or “Pomodoro”.
2. For a countdown, tap a quick time such as “10 min” to start at once, or type hours, minutes and seconds and press “Start”.
3. On the stopwatch, press “Start”, then “Lap” for each split. “Copy laps” copies the table for a spreadsheet.
4. For Pomodoro, set the focus and break lengths, add a task and press “Start”. Breaks follow on their own if you leave that box ticked.
5. Press the expand button beside the tabs (or F) for focus mode, where only the ring and its buttons fill the screen.

• Countdown timer with eleven quick times from 1 minute to 1½ hours, your own time up to 99 hours, “+1 min”, and an optional label such as “Oven”.
• Big glowing progress ring with the end time shown underneath (“Ends at 14:32”).
• Stopwatch with hundredths, lap and total times, fastest lap in green and slowest in red, and one-tap copy.
• Pomodoro with your own focus, short-break and long-break lengths, how many rounds before the long break, and auto-start for breaks and focus sessions.
• A small task list: pick a task and each finished focus session is counted against it.
• Today’s finished focus sessions and minutes, reset each day, stored in this browser.
• Keeps exact time in background tabs and picks up where it left off if you reload or close the page.
• Soft three-note chime with volume control, a flashing tab title, and optional system notifications.
• Keyboard shortcuts: Space start or pause, R reset, L lap, S skip, F focus mode, Esc to leave it.

• Browsers only allow sound after you have clicked something, so start the timer with a click or key press rather than leaving it to auto-start after a reload.
• Phones often pause web pages when the screen locks. The time stays correct, but the chime may wait until you return, so for an alarm you must hear, keep the screen on.
• Use the label on the Timer tab when you run several things: the label appears in the tab title and the notification, so you know which one finished.
• Notifications need your permission once. Chrome on Android doesn’t allow this kind of page notification, so rely on the chime and the tab title there.
