Question 1

Does the countdown timer make a sound when it finishes?

Accepted Answer

Yes. Tick the "Sound alarm when done" checkbox before starting the timer. When the countdown reaches zero, the browser plays a short ascending beep using the Web Audio API — no external file or plugin needed. The sound works in all modern browsers. If you hear no sound, check that your device is not muted and that your browser has not blocked audio. The Pomodoro timer always plays a sound at the end of each phase.

Question 2

What is the Pomodoro technique and how does this timer implement it?

Accepted Answer

The Pomodoro technique alternates focused work sessions with short breaks. The classic pattern is: 25 minutes work → 5 minute break, repeated 4 times, followed by a 15–30 minute long break. This timer automates the full cycle: it tracks which session you are on, shows the phase name (Work Session 1, Short Break, etc.), and automatically advances to the next phase after each one finishes with an alarm. You can customise the work, short break and long break durations.

Question 3

How do lap times work in the stopwatch?

Accepted Answer

Press Lap while the stopwatch is running to record the current elapsed time without stopping the clock. The lap table shows: the lap number, the duration of that specific lap, the variance from the average lap time (shown as + or - with the difference), and the total elapsed time. The fastest lap is highlighted green, the slowest red. A summary at the bottom shows best, worst and average across all laps. Press "Copy Laps" to export the table to your clipboard for pasting into a spreadsheet.

Question 4

What are the quick preset timers?

Accepted Answer

The presets set the countdown instantly: 1 min (short tasks), 5 min (breaks), 10 min (focused tasks), 25 min (one Pomodoro), 45 min (lecture or class), 1 hour, 1.5 hours and 2 hours. Click any preset and then Start. You can also type custom values in the hours, minutes and seconds fields for any duration up to 23:59:59.

Question 5

Does this timer work when the browser tab is in the background?

Accepted Answer

The countdown and Pomodoro timer use setInterval which continues running when the tab is in the background in most browsers. However, some browsers throttle JavaScript in background tabs to save battery, which may cause slight inaccuracies (usually 1–2 seconds over a long session). For critical timing needs, keep the tab active or use a dedicated application. The stopwatch uses Date.now() for elapsed time measurement, which is accurate regardless of tab focus.
