Cooking, presenting, doing a quick focus sprint: a reliable countdown timer is one of the most-used utilities on a laptop. The ChrysoKit Countdown Timer keeps it simple and trustworthy.
Why use it
Browser timers traditionally lose accuracy when the tab is in the background. Ours uses the timestamp of when it started, so it stays accurate regardless of tab state.
How to use the Countdown Timer
- Enter hours, minutes and seconds.
- Press start.
- Pause or reset at any time.
- Hear the alert when time is up.
Features worth knowing
Background-safe
Stays accurate even if the tab is hidden.
Audio alert
A clear notification sound when the timer hits zero.
Big readout
Designed to be readable from across the room.
Pro tips
- Browser tabs can mute audio by default. Allow sound on the page once and the alert will play reliably.
- Pin the tab to keep it visible during long sprints.
- Stack multiple timers in separate tabs if you need parallel countdowns.
Privacy first. The Countdown Timer runs entirely in your browser. Nothing you enter is sent to a server.
