30 minute timer

Half an hour, preset. A good length for workouts, power naps, oven dishes and longer focus blocks — start it and get on with the thing itself.

When the time is up you hear three beeps and the tab title flashes — no account, nothing to install.

What a 30 minute timer is good for

Like every timer on this site, this countdown is computed from timestamps rather than counted ticks, so it ends on time even if the tab sits in the background — the alarm still sounds the moment you bring the tab forward, and the title keeps flashing until you do. Need a different length? Use the full countdown timer to set any duration, or pick another preset: 5 minutes, 10 minutes, 25 minutes, 60 minutes.

Frequently asked questions

Will it still be accurate after half an hour in a background tab?
Yes. The remaining time is recomputed from timestamps on every frame, so background throttling cannot accumulate error — the countdown ends at the true thirty-minute mark.
Can I make it 35 minutes instead?
Tap +1:00 five times, or use the full countdown timer to set any length directly.
