How the timer works
Last updated 10 November 2026
A timer counts down from a length of time you choose. People use one for cooking, study sessions, workouts, meetings, laundry and presentations. This one is free, needs no sign-up and works on a phone or a computer.
Set the hours, minutes and seconds, or tap a quick time, then press Start. You can pause and resume, and Reset puts it back to the time you set. When it reaches zero the panel changes colour, the message reads Time is up, and a short beep sounds if the beep box is ticked.
How it works
The timer does not count ticks. A browser may slow down a page that is in the background, which would make a tick-counting clock run late. Instead, when you press Start the timer remembers the moment on your device's clock, and every time it redraws it works out how much time has gone by since then. Pausing banks the time already used, and resuming starts a new measurement.
For example, a 5 minute timer checked 90 seconds after it started shows 0:03:30, even if the page was only redrawn once. If the page was hidden for 15 minutes, it shows 0:00:00 and Time is up when you come back.
The beep
The beep is generated by your browser using the Web Audio feature, so there are no sound files to download. It is three short tones. The sound is scheduled on the audio clock when you press Start, which keeps running when the tab is in the background, so it still sounds close to on time. Browsers only allow sound after you press a button, which is why Start matters.
Accessibility and motion
Every control can be used with a keyboard and has a visible label. The running clock is not read out every second, because that would be tiring for a screen reader user. The page announces only when the timer starts, pauses, resumes, resets and finishes. If your device is set to reduce motion, the time is up panel changes colour without any animation.
Handy times
A common study method is 25 minutes of work followed by a 5 minute break, which together is 30 min. Set 25 minutes, work until the beep, then set 5 for the break. For cooking, check the packet and add a minute or two for resting. For a presentation, set the slot length and watch the clock rather than your phone.
- 1 minute: brewing tea, a plank, a quick stretch.
- 5 and 10 minutes: a short break or a quick tidy.
- 30 minutes and 1 hour: a work block or a class.
Other clock tools
To measure time that is already running, use the stopwatch. To count down to a date or an event, use the countdown timer. To add up hours, use the time calculator.
Privacy
The timer runs in your browser. It does not ask for notification permission, does not keep your screen awake and does not store the time you set.
Things to watch
- Keep the tab open until the timer finishes. If your phone locks or the browser is closed, the page may stop.
- Do not rely on any web timer for anything where timing is critical to safety.
Like every tool on MoneyMzansi, this one works in your browser with no account and no upload.
