Online Timers & Clocks
Set a timer, run a stopwatch or start a Pomodoro session in one click.
These free online timer and clock tools cover timekeeping without installing anything: an online timer for cooking, workouts and exams, a stopwatch with lap times, an alarm clock that rings at a set time, and a Pomodoro timer for 25-minute focus sessions with breaks. Musicians get a metronome with adjustable BPM, and the countdown to date tool shows exactly how long until a wedding, launch or holiday.
Each tool starts in one click and shows big, readable digits that work from across the room. They run in your browser, free and without accounts. One honest limitation stated up front: browser tools ring only while the tab is open, so keep the tab running for alarms and long timers rather than closing the browser and hoping.
Frequently asked questions
Are these timers free?
Yes, every tool is free and unlimited with no sign-up. Open the page and press start.
Will the alarm still ring if I close the tab?
No. Browser tools only run while their tab exists, so keep the tab open (in the background is fine). For wake-up alarms when your computer might sleep, a phone alarm is the more reliable choice, and we would rather say so than let it fail on you.
Do the timers keep accurate time in background tabs?
Yes. They compute elapsed time from the clock rather than counting ticks, so even when the browser slows background tabs, the timer stays accurate and the alarm fires on schedule.
Do they work on phones?
Yes, all tools work in mobile browsers with touch-friendly controls. Keep the screen awake for long timers, as phones aggressively pause background browser tabs.
Can I use the Pomodoro timer with my own intervals?
Yes. The classic 25/5 pattern is the default, but work and break lengths are adjustable if you focus better with 50/10 or something else.
