What is Timer?

A straightforward countdown timer that lets you set hours, minutes, and seconds, then counts down to zero with an audible alert. Use it for cooking, workouts, study sessions, or anything else on the clock.

Pick a duration with hour, minute and second fields, or tap one of the six preset buttons for the most common intervals (1, 5, 10, 15, 25, 30 min). The last eight durations you ran are saved to localStorage so a quick re-run is one click away. Choose an alarm before you start — a warm bell, a sharp beep, a gentle chime, or silent for shared rooms — and tap any option to preview it. While the timer runs, the live countdown is mirrored in the tab title and the progress bar shifts from green to amber to rose as time runs out. When time hits zero, your chosen alarm plays and an optional system notification fires, so you stay on track even with the tab in the background.

How to use

  1. Set the desired duration using the hour, minute, and second inputs.
  2. Press Start — the countdown begins immediately with a live display.
  3. When the timer reaches zero, an alarm sounds. Tap Reset to set a new duration.

When to use

  • Running a 25-minute Pomodoro focus block followed by a 5-minute break.
  • Cooking a steak or pasta where overshooting by 30 seconds ruins the dish.
  • Capping a workout interval like a 45-second plank or 3-minute HIIT round.

Result

Set 25 minutes for a focused study session, hear the alarm when time is up, then reset to 5 minutes for a break.

FAQ

Will the timer keep running if I switch to another tab?
Yes. The end-time is stored as a timestamp and the display catches up the moment the tab regains focus. Modern browsers throttle background timers, but the math is based on the system clock so the alarm still fires at the correct moment.
Why isn't my notification appearing when the timer ends?
Notifications require explicit permission per site. Tap 'Enable notifications' once and accept the browser prompt. If you previously blocked them, you'll need to clear the site permission from the address bar's lock icon and grant it again.
Can I pause and resume the timer?
Yes. Pause freezes the remaining time, and Resume continues from exactly where you stopped without skipping ahead. Reset clears everything and returns you to the input fields with the duration you typed in.
How are recent durations chosen?
Each time you press Start, the duration is added to the top of the history list and any duplicate is removed. The list keeps the last eight unique durations and persists across reloads through localStorage. Tap any chip to reload that duration.
Does the alarm play if my phone is on silent?
The alarm uses the Web Audio API, which respects the device's media volume rather than ringer settings. On most phones silent mode mutes notifications but not media — turn the volume slider up before starting if you want to be sure the beep is audible.
