Three timers in one page. The countdown takes any hours/minutes/seconds or one-click presets like 1, 5, 10, 25 or 60 minutes, and when time is up it beeps and flashes the screen. The stopwatch is accurate to 1/100 s with laps, highlighting the fastest and slowest lap. The Pomodoro timer cycles 25 minutes of focus and 5 minutes of rest, with a long break every 4 pomodoros — all durations adjustable. Timing uses the browser's high-resolution clock, so it stays accurate in background tabs, and the page title shows the remaining time. Great for classes, exams, meetings, workouts, cooking and deep work.

## How to use

## FAQ

### Will the timer drift if I switch tabs or minimize the browser?

No. The time is computed from the difference between the start moment and now rather than by counting ticks, so even when the browser throttles background tabs the time stays exact, and the countdown alarm still fires.

### Why is there no sound when the countdown ends?

Browsers only allow audio after you interact with the page; the timer unlocks audio when you press Start. Make sure "Beep when finished" is on and neither your system nor the tab is muted — use "Test sound" to check.

### What is the Pomodoro Technique?

It is a time-management method: work with full focus for 25 minutes (one "pomodoro"), then take a 5-minute break, and after every 4 pomodoros take a longer 15–30 minute break. The tool switches phases for you and alerts you at each change; every duration is adjustable.

### Do I need to sign up or install anything?

No. Just open the page — it is completely free, runs entirely in your browser and collects no data.
