# Free Timer Online — Countdown, Stopwatch and Full-Screen Clock — diStudero

> A free online countdown timer, stopwatch and set of full-screen clocks that run in the browser. No sign-up, no download, no ads.

## Quick answer

diStudero's free timer runs at https://www.distudero.com/en/free/timer. Pick a duration and the countdown starts immediately — there is no start button to find and no account to create. It is free permanently, not a trial.

## The countdown timer

- **One-tap durations** — 1, 3, 5, 10, 15, 20, 25, 30, 45 and 60 minutes.
- **Pomodoro** — the 25-minute preset is a focus block; the 5-minute preset is the break.
- **Stopwatch** — counts up from zero instead of down, with the same pause and reset.
- **Extend while running** — "+1 min" and "+5 min" add time without restarting.
- **Accurate in a background tab** — the countdown is measured against the device clock rather than by counting ticks, so it stays correct when the tab is hidden or the laptop briefly sleeps.
- **Remaining time in the tab title** — readable without switching back to the tab.
- **Chime at zero** — a short two-note tone, synthesised in the browser.

## The full-screen clocks

Animated full-screen scenes that show the current time, meant to be left running on a screen while you work. Each scene caps its own frame rate and pauses entirely when the tab is hidden (measured 3–4% of one CPU core at 1920x1080), and canvas-based scenes offer a quality setting.

- Aurora — drifting northern lights, four colour moods.
- Rain — layered night rainfall with shifting wind.
- Lava — slow merging blobs, like a lava lamp.
- Minimal — oversized time on black with an hour progress line. Lightest on battery.
- Word clock — the time spelled out of a letter grid, in English, Czech or Polish.
- Slide — digits that slide down to replace each other.
- Columns — endless reels of numbers, current time lit in the middle.

Each is at https://www.distudero.com/en/free/timer/<name> (aurora, rain, lava, minimal, textgrid, slide, columns).
