Online Timer

The presets cover the lengths people actually set the most — 1, 3, 5, 10, 15, 25, 30, and 60 minutes — so one tap gets you a timer for tea, a quick break, a focus block, or a class activity. Need something else? Type the hours, minutes, and seconds directly instead of clicking through a picker.

While it is running, the time left shows in the tab title as well as on the page, so you can read it from across the room even with the tab in the background. Pause and resume keep the remaining time exactly where you left it, and reset brings it back to the length you set, not to zero.

At zero, the default tones play from Web Audio right in the browser, synthesized rather than downloaded. The optional environment chime is the one exception — picking it downloads a small audio file, and falls back to a synthesized tone if that file cannot load.

Because the countdown is worked out from the system clock instead of ticking down on its own, a timer that spent its final minutes in a throttled background tab still ends at the right second instead of finishing late.

A timer is really just one number, so that number lives in the link — add a length to the address and you get a timer that opens already set, ready for you to press Start. That is the fastest way to hand a class, a team, or a workout buddy the exact same timer without walking them through the settings.

The timer is free, with no cap on how many you run. Your last length is remembered in your browser, so it opens right where you left it, and nothing is sent anywhere else. Once you need to turn tracked time into hours worked and pay, that is what the hours calculator and the timesheet are for.
