About the Countdown Timer

A countdown timer measures time from a value you set down to zero and alerts you with a sound when it finishes. It is handy whenever you need to track "how many minutes left" — cooking, studying, breaks, presentations, and more. This tool requires no installation and runs entirely in your browser. The times and timer names you enter are never sent to any server.

  • Alarm NotificationPlays a Web Audio alarm when time is up and shows the remaining time and finish in the tab title, so you never miss it.
  • Pause & ResumeStart, pause, resume, and reset intuitively. Keyboard shortcuts (Space and R) are supported too.

FAQ
