About the Online Timer & Stopwatch
Whisser Timer & Stopwatch combines three tools in one page: a countdown timer with an alarm, a stopwatch with lap times, and a Pomodoro timer for focused work sessions. Timing is based on your device clock rather than counting ticks, so it stays accurate even when the tab is in the background. Everything runs in your browser with no account.
How to use
- Choose Timer, Stopwatch or Pomodoro at the top.
- For a countdown, tap a preset or click the hours, minutes and seconds to type a time, then press Start or the Space bar.
- For the stopwatch, press Start, then Lap (or L) to record split times. Press Pause and Reset to start over.
- For Pomodoro, set your focus and break lengths, then start a session. Breaks follow automatically when Auto-start is on.
- Use the expand button or F for a distraction-free fullscreen view, and enable desktop notifications if you work in other tabs.
Frequently asked questions
Will the timer keep running in a background tab?
Yes. The timer, stopwatch and Pomodoro clock are calculated from your device clock, so they stay accurate when you switch tabs or minimize the window. The remaining time is also shown in the browser tab title.
How do I stop the alarm?
Press Stop alarm, the Space bar, or the Stop button in the notice at the bottom. The alarm repeats every few seconds until you stop it and turns itself off after two minutes. You can also press +1m to snooze for one more minute.
Can I get a notification when the timer ends?
Yes. Turn on Desktop notification in the Alerts panel and allow notifications when your browser asks. You will then see a system notification even if you are working in another tab.
What is the Pomodoro technique?
It is a time management method where you work in focused sessions, traditionally 25 minutes, separated by 5-minute short breaks, with a longer 15 to 30-minute break after every four sessions. You can change all of these lengths here.
Which keyboard shortcuts are available?
Space starts or pauses the current mode, R resets it, L records a lap on the stopwatch and F opens or closes the fullscreen focus view.
Is the online timer free?
Yes. It is free, needs no account, and your settings and daily Pomodoro count are stored only in this browser.
