Online Timer — Free Countdown Timer with Alarm

A free online timer that does exactly what you need and nothing else. Type any length from 1 to 180 minutes in the box and press Set, or tap one of the presets under the clock, then hit start. It keeps accurate time in a background tab, chimes when it's done (or stays silent — your choice), and goes full screen for a room to see.

How to Use This Countdown Timer

1. Choose a time — type minutes into the box and press Set, use −1/+1 to fine-tune, or pick a preset.
2. Press start — or tap the ring. The time left also shows in your browser tab.
3. Get on with it — switch tabs or apps; the alarm is scheduled to sound on time.
4. Pause or reset any time. Your timer is remembered if you reload the page.

What Makes a Good Online Timer?

• It keeps time when you're not looking. Many browser timers drift or go silent in a background tab. This one counts from the clock and schedules its alarm in advance.
• It's readable from across a room. Full screen scales the ring and digits to fill any display.
• It respects quiet spaces. Switch the sound off for libraries, exams and meetings.
• It doesn't ask for anything. No account, no download, no ads.

Put It on Your Own Site
