How to use it
- Tap a preset such as 5 min or 25 min to start straight away, or type hours, minutes and seconds.
- Press Start. Use Pause and Resume as needed, and Reset to go back to the set time.
- When the time is up, a short beep sounds (if enabled), the screen shows “Time’s up!” and the tab title changes so you notice it from another tab.
How it keeps accurate time
The timer stores the moment it should finish and, on every screen refresh, shows the difference between that moment and the current time. Browsers slow down scripts in background tabs, but because the end time is fixed, the countdown does not fall behind: when you come back, it shows the right time.
Ideas for presets
- 1–3 minutes: brushing teeth, steeping tea, a plank.
- 5–10 minutes: a short break, boiling eggs, a quick tidy-up.
- 25 minutes: one Pomodoro work session, followed by a 5-minute break.
- 45–90 minutes: a lesson, an exam section, a baking time.
