Frequently asked questions
What is a 15 minutes timer good for?
It works well for a stand-up meeting, a short study sprint, a power break, or letting a dish cool before serving.
Does the timer keep working in a background tab?
Yes. It stores the exact end time and compares it with your device clock, so it is accurate even if the browser slows down the tab. The alarm sounds when the time is up.
What happens if I reload the page?
The timer carries on from where it was. Its state is saved in your browser only.
Can I choose the alarm sound?
Yes. Pick from four tones and set the volume. The sounds are generated in your browser, with no audio files.
Can I keep my screen on while it runs?
Turn on “Keep screen on” if your browser supports it. It stops the display from dimming until you leave the page.
Are there ready-made timers for common times?
Yes. Open the timers by duration below, for example the 5 minute timer or the 10 minute timer, each on its own page.
A simple 15 minutes countdown
A 15 minutes timer is handy for a stand-up meeting, a short study sprint, a power break, or letting a dish cool before serving. Press Start and the countdown begins at once. The digits are large enough to read from across the room, and an alarm sounds when the time is up, even if this tab is in the background. You can add a minute while it runs, repeat it automatically, or switch to another duration from the list further down this page.
The timer calculates the remaining time from your device clock instead of counting ticks, so it stays accurate when the browser slows down hidden tabs. If you reload the page the countdown carries on from where it was. Pick a tone and volume, go fullscreen for a classroom or a stream, and turn on keep-screen-on if your browser supports it. It is free, works on phones and computers, and needs no account.
