- A practice exam or a timed essay.
- A study session, followed by a proper break.
- A parking meter or a booking you do not want to overrun.
- Anything slow in the oven.
How this timer works
- It remembers the moment it will end, so it stays right when you switch tabs or your phone locks.
- At zero it plays a few short beeps, vibrates on phones that can, and shows "Time's up" in the tab title.
- While it runs it asks the screen to stay on. Full screen makes the numbers big enough to read across a room.

Questions people ask
How do I set a one-hour timer on my phone?
On iPhone, say "Hey Siri, set a timer for one hour", or use the Timers tab in the Clock app. This page also works in the phone's browser.
Can I set a timer for longer than an hour?
Yes. The custom timer on this site takes any length up to 24 hours. For something days away, use a countdown instead.
Does the timer work without an internet connection?
Once the page has loaded, yes. The timer runs in your browser and does not need the network to count down or to beep.
Counting down to a date rather than a few minutes? The countdown maker works for any day, and with Pro the Countdown app puts it on your iPhone Lock Screen.
