Overview
Three time tools in one
This tool combines the three timing tools people reach for most: a countdown timer with an audio alarm, a stopwatch with lap support, and a Pomodoro timer for focused work. Everything runs in your browser, the alarm needs no audio file, and the countdown stays accurate even when the tab is in the background.
Set it and forget it
Countdown timer
Set hours, minutes, and seconds, or tap a preset (1, 3, 5, 10, 15, or 30 minutes). Press Start and a ring counts down around the clock. When it reaches zero, a beep plays and the display flashes. Because the timer tracks the real target end time rather than counting ticks, it stays correct even if your browser throttles the background tab — a common problem with naive timers.
Cooking
Boil eggs, steep tea, rest a steak. Tap a preset and listen for the beep.
Workouts
Time intervals, rest periods, planks, and HIIT rounds.
Studying
Time-box revision sessions so you take regular breaks.
Presentations
Keep a talk on schedule with a visible countdown.
Time anything open-ended
Stopwatch
Start from zero and time as long as you need, down to the hundredth of a second. Press Lap to record split times — each lap shows both the total elapsed time and the gap since the previous lap. Useful for running intervals, comparing attempts, and any activity where you want to measure segments.
Focus in blocks
Pomodoro timer
The Pomodoro technique, created by Francesco Cirillo in the late 1980s, breaks work into focused intervals separated by short breaks. The classic rhythm:
- Work with full focus for 25 minutes
- Take a 5-minute break
- Repeat — after four focus blocks, take a longer 15-30 minute break
Our Pomodoro mode automates the cycle: it switches between focus and break automatically, beeps at each transition, and counts your completed sessions. You can adjust the focus and break lengths to suit your own rhythm.
Why it works
No file needed
How the alarm works
The beep is generated on the fly with the Web Audio API, so there's nothing to download and no external sound to load. Make sure your device isn't muted. Browsers require a user interaction before playing audio, which happens automatically when you press Start, so the alarm is ready by the time the countdown ends.

Common questions
Does the timer keep running in a background tab?
Yes. It's based on the actual end time, so even if the browser throttles the tab, the remaining time stays accurate and the alarm fires at the right moment when you return.
Why didn't the alarm make a sound?
Usually because the device is muted or the browser blocked audio. Pressing Start unlocks audio in most browsers. Check your volume and that the tab isn't muted.
Can I set a timer for more than an hour?
Yes. The hours field accepts up to 99 hours, so you can set very long countdowns. For very long durations, keep the tab open.
What's a good Pomodoro setting for studying?
The classic 25/5 (25 minutes focus, 5 minutes break) works for most people. If you find your focus dips sooner, try 20/5. For deep work you're already absorbed in, 50/10 can keep momentum while still forcing breaks.
