Free Countdown Timer
NToolHub’s Countdown Timer counts down from any duration you set — hours, minutes, seconds — and sounds a clear alarm when time expires. A live progress bar shows how much time remains at a glance. Use it for cooking, workouts, exams, presentations, and productivity sprints, with handy presets for common durations.
Tip: preset buttons
How to Use the Countdown Timer
- Set hours, minutes, and seconds — or tap a preset like 5 minutes.
- Click “Start” to begin the countdown.
- Pause and resume, or reset any time.
- A loud alarm sounds when the countdown reaches zero.
Features
Hour/minute/second inputs with five quick presets (1 min to 1 hour), pause/resume that preserves remaining time, a smooth progress bar, a TIME UP display state, and a Web Audio alarm that plays four beeps — no audio files needed.
Benefits & Use Cases
Time-boxing keeps meetings, study sessions, and workouts on track. The audible alarm means you do not have to watch the screen, and presets make starting a standard Pomodoro or steeping tea a one-click affair.
Tips
Keep your volume up and the tab open so you hear the alarm. For repeated intervals, use the preset buttons to reset quickly. If your browser blocks sound, interact with the page once first — starting the timer counts.
Frequently Asked Questions
Will the alarm sound if the tab is in the background?
Usually yes, as long as the browser is running and not muted. For critical timing, keep the tab visible.
Can I pause and resume the countdown?
Yes. Pause freezes the remaining time exactly, and Start resumes from where you stopped.
What is the maximum countdown?
You can set up to 99 hours, 59 minutes, and 59 seconds.
Why did I not hear the alarm?
Browsers require a user gesture before playing audio. Clicking Start counts as that gesture. Also check your system volume and that the tab is not muted.
