A big, full-screen 13 minute timer. Press Start and the countdown fills your screen in large, glance-able digits; when it reaches zero an alarm sounds and the screen flashes so you notice from across the room. Click for fullscreen, and use Start / Pause or just click the screen to control it.
Nothing to install and no account — the 13 minute countdown runs live in your browser, keeps your screen awake while it counts, and beeps when time is up. Need a different length? Try the 30-minute-timer or 1-hour-timer, or keep the current time in view with the flip clock.
What people use it for
Cooking & tasks
Set the 13 minute timer for steeping tea, a workout round, laundry, or anything on the stove, and let the full-screen alarm call you back.
Focus & study blocks
Run a 13 minute block of focused work with the countdown visible on a spare monitor, then take a break when it rings.
Presentations & meetings
Keep a talk, demo or breakout on schedule — a big shared countdown is far clearer than a phone timer on a table.
Frequently asked questions
Is the 13 minute timer free?
Yes — no app, no account, no download. Open the page, press Start, and it runs in your browser.
Does it make a sound when it ends?
Yes. When the countdown reaches zero it plays a repeating alarm beep and the screen flashes. Press Reset or Pause to stop it.
Can I pause and resume?
Yes. The Start button becomes Pause while running; click it (or click the screen in fullscreen) to pause and resume. Reset returns it to the full time.
Will it keep running if I switch tabs?
The countdown keeps time in the background, and the alarm still fires when you return. For a reliable alarm keep the tab open; the page also requests a screen wake-lock so the display stays on while it counts.
Can I change the length?
This page starts at 13 minute. Use the +1 min button to extend it, or pick another preset from the Timers menu for a different duration.
