Pomodoro Technique — 25 Minute Timer

The Pomodoro Technique breaks work into 25-minute focused intervals separated by 5-minute breaks. Tap the 25 min preset, press Start, and work with complete focus until the chime fires. Then tap 5 min for your break. After four Pomodoros, enjoy a 30-minute break. This structured method prevents mental fatigue and is used by millions of students and professionals daily.

Timer vs Alarm Clock — Key Difference

A countdown timer is duration-based — "alert me after 25 minutes". An alarm clock is time-of-day-based — "alert me at 7:00 AM". Use a timer for cooking, workouts and Pomodoro. Use an alarm for scheduled wake-ups and meetings.

Frequently Asked Questions

Does the timer keep running if I switch tabs?

Yes. The timer references your device's high-resolution system clock, not a simple JavaScript interval, so it stays accurate when you switch to other tabs, minimize the browser, or briefly sleep the screen. The chime fires at the correct moment regardless.

Why doesn't the alarm sound play when it reaches zero?

Browsers require at least one user interaction — a click, tap, or keypress — on the page before allowing audio playback. If the chime doesn't play, click anywhere on the page once and restart the timer. Also verify your system volume is not muted and the browser tab is not silenced.

Can I run multiple countdown timers simultaneously?

Yes — open multiple browser tabs on vattoo.site/timer/, each set to a different duration. Each tab counts down independently and fires its own audio alert at zero. This works great for managing multiple cooking items or parallel work tasks.

What is the maximum timer duration I can set?

Up to 99 hours, 59 minutes and 59 seconds — almost 4 full days. This covers everything from a 30-second kitchen timer to a multi-hour process or overnight monitoring timer.

Is the countdown timer free?

Yes, completely free. No registration, subscription or payment is ever required to use any timer feature.
