Countdown Timer
Set hours, minutes, and seconds or a quick preset; get a big countdown, a progress bar, a tab-title timer, and a beep at zero.
Processed locally in your browser — nothing is uploaded.
The remaining time also shows in the browser tab, and a short beep plays when the timer ends (keep this tab's sound on).
About Countdown Timer
A no-nonsense countdown: set a duration or tap a 1/5/10/25-minute preset, then start. The big display and progress bar show where you are, the remaining time mirrors into the browser tab so you can switch away, and a short synthesized beep plays when time is up — no audio files, no notifications permission.
Common uses
- Run 25-minute focus blocks with the preset
- Time tea, laundry, or oven checks while working in other tabs
- Give talks and exercises a hard stop
Example
Input
Preset: 25 min
Output
25:00 counting down, tab shows 24:59… and beeps at zero
Limitations
- The end-of-timer beep needs the tab's sound unmuted; browsers may block audio until you've interacted with the page.
