Twenty minutes is the classic length for a power nap: long enough to feel better, short enough to wake up without the fog. Press Start and lie down.
What people use a 20 minute timer for
- A power nap.
- The 20-20-20 rule for screens: every 20 minutes, look at something 20 feet away for 20 seconds.
- A short run, a yoga flow or a stretching routine.
- Letting dough rest or meat come to room temperature.
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 long should a power nap be?
Somewhere between 10 and 20 minutes. Much longer and you are more likely to wake up groggy.
Can I run it again for the next 20 minutes?
Press Reset and Start again, or just press Start after it has finished and it begins a fresh 20 minutes.
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.
