Thirty seconds feels like nothing until you spend it in a plank. Press Start and the clock counts down from 0:30, then beeps and shows "Time's up" in the tab title.
What people use a 30 second timer for
- A plank, a wall sit, or one exercise in a circuit of 30 seconds on and 30 seconds off.
- An elevator pitch. If you cannot say what you do before the beep, cut it down.
- Turns in charades, Pictionary or any word game where each player gets half a minute.
- Melting chocolate in the microwave 30 seconds at a time, stirring in between so it does not scorch.
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
Is a 30 second plank good?
For a beginner it is a good start. Keep your body in a straight line for the full 30 seconds, then add time over the following weeks. Good form counts for more than a long hold.
How many words fit in a 30-second speech?
Roughly 65 to 75. Most people speak at about 130 to 150 words a minute, so write to that length and then time it out loud.
Does it vibrate on a phone?
On phones that let websites vibrate, yes, along with the beeps. Safari on iPhone does not, so there you get the sound only. Make sure the phone is not on silent.
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.
