Countdown Timer
Set a countdown in minutes and seconds and get an audible alarm the moment it hits zero — great for cooking, breaks, or timed tasks.
A countdown timer solves a different problem than a stopwatch does — instead of measuring how long something took, it enforces how long something should take. That distinction shows up everywhere: a debate moderator doesn't care how long a rebuttal actually lasted, they care that it stops at exactly two minutes. A parent doesn't need to know precisely how long screen time ran, they need the tablet to make a noise at thirty minutes so they don't have to keep checking a clock themselves.
The reason a countdown timer is genuinely useful software, and not just a stopwatch running backward, comes down to that alert at zero. Without a clear, audible signal when time's up, a countdown is just a number decreasing on a screen that you still have to watch — which defeats half the purpose of setting a timer in the first place. The value is in being able to walk away and trust that you'll be told when to come back.
This version keeps that promise simple: set any duration in minutes and seconds, press start, and get a sound plus an on-screen message the moment it hits zero — nothing to configure, no account, and it works identically whether you're timing a two-minute egg or a two-hour exam. Below, you'll also find preset versions for the most commonly needed durations, from a one-minute timer up to a full hour, each pre-loaded so you don't have to type the numbers in yourself.
- Enter your minutes and seconds.
- Press Start to begin the countdown.
- Listen for the beep when time's up.
- Press Reset any time to set a new duration.
The beep plays through your browser's audio, so you'll hear it even if the tab isn't focused, as long as the tab stays open.
Currently minutes and seconds only — for longer durations just enter the total in minutes (e.g. 90 for 1.5 hours).
Yes, it works in any modern mobile browser, but keep the screen on or the timer may pause when the phone sleeps.
