This timer draws 25 minutes as 20 concentric rings; one empties every 1.3 minutes, so a glance shows how far along you are without reading a digit. It chimes at zero, keeps counting in a background tab, runs fullscreen, and exports as a free MP4 video. Handy for a Pomodoro work interval, a writing sprint, or roasting nuts without burning them.
The classic focus rhythm runs twenty-five minutes on, five off, with a longer rest after every fourth round. It works because the end stays in sight: nearly anything that pings or knocks can wait that long. Whatever still matters when the round ends gets its five minutes.
Twenty-five minutes is the pomodoro length, and it owes its fame to Francesco Cirillo, who in the late 1980s timed his study with a kitchen timer shaped like a tomato. The pomodoro page runs the full cycle, four blocks with five-minute breaks that start on their own. This page is the single block on its own: one dial, one task, one chime. Each ring lasts seventy-five seconds, so four rings is five minutes and the face divides into five clean fifths.
The cycle is the right tool for a morning of work. A single twenty-five is the right tool for one thing you have been avoiding: a difficult email, the first page of a report, a form. Start the dial, do only that thing, and when the chime sounds you are allowed to stop. Most people do not, but the permission is what gets the dial started.
Writers use twenty-five minutes because it is long enough to get a few hundred words down and short enough that the blank page does not win. The rule is that the cursor keeps moving until the chime; editing waits for the next block. The rings are silent, so nothing on the screen ticks at you while you write.
Twenty-five is five five-minute pieces, changing at every fourth ring. A revision session can run five topics that way; a workout can run five stations. If you would rather have a chime at each change, the 5 minute dial restarted five times does it.
If the chime keeps arriving mid-sentence, the block is too short for the work, and the 50/10 page or a plain 30 minute dial suits it better. If starting is the problem, the 20 minute dial is a gentler first step. The card also has a twenty-five-minute video, and the timers page has the whole set.

A radial timer is a free online countdown timer you set in one click: pick a length, press Start, and an alarm sounds at zero.

No download, no sign-up.
