Online countdown timer – Smart, customizable, and easy to use

Looking for a simple yet powerful online countdown timer? Whether you're timing a study session, workout routine, or cooking task, our free online timer has everything you need—and more. With advanced customization, multiple presets, audio alerts, and exportable data logs, this digital timer tool is built to support your productivity and focus.

1. Choose hours, minutes, and seconds

At the core of our online timer is its easy hour-minute-second selector. Instead of manually typing the countdown time, you can quickly adjust it using dropdowns or by clicking on the intuitive number selectors.

  • Choose any duration from a few seconds to several hours.
  • No need to refresh the page—adjust the timer on the fly.
  • Real-time validation ensures accurate timing.

2. One-Click preset buttons for popular timers

To save time, we’ve included preset timer buttons for commonly used countdown durations. These buttons appear prominently and let you instantly activate durations like:

  • 5 minutes for a coffee break
  • 15 minutes for a quick study block
  • 25 minutes (Pomodoro-style) for focused work
  • 1 hour for meetings or events

These presets are fully configurable, so you can add your own favorite durations later on.

3. Choose an alarm sound & preview It

Select from multiple alarm tones like bell, buzzer, chime, or beep. Preview each sound with one click and choose the best alert for your environment.

4. Control how long the sound plays

Configure your alarm duration from 5 to 30 seconds or even loop it until manually stopped. Never miss an important alert again.

5. Add a custom timer title

Add a clear label like “Break Time” or “Next Meeting” above your timer to give your session purpose and context.

6. Key timer controls: Start, pause, stop, restart

Use intuitive control buttons to manage your countdown in real time. Pause and resume anytime without resetting your duration.

7. Exportable timer data: Excel, csv, delete

All actions are logged and can be exported in Excel or CSV format. Perfect for productivity tracking, classroom use, or professional reporting.
