This timer draws 40 minutes as 20 concentric rings; one empties every 2 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 an ACT essay, baking stuffed peppers, or an easy-pace 5K run.
Forty minutes is half a rugby match, a timed essay, an easy 5K, and a tray of stuffed peppers. The dial makes it simple: each ring is two minutes, so the number of dark rings doubled is the minutes gone, and ring ten is twenty minutes.
The ACT writing section gives forty minutes for one essay, and forty is also a common length for timed essays in school exams and university finals. Practising against the dial is the point: five rings for planning, thirteen for writing, two for reading it back. Fullscreen the dial on a second screen and it works as the exam clock, silent until the chime.
Five kilometres at eight minutes per kilometre is forty minutes, which is a comfortable jog for a regular runner and a fair goal for a beginner. Start the dial on the first stride. If the chime lands before the finish line, the pace was easy; if you are back early, the next target is the 35 minute dial.
Halved peppers stuffed with cooked rice and mince bake covered for about forty minutes in a moderate oven, then a few minutes uncovered to brown. Start the dial when the dish goes in. At the chime the peppers should be tender when pierced and the filling hot through; take the foil off and give them five more minutes on a fresh dial for colour.
Rugby union is two forty-minute halves. Coaches running a training match or a small-sided game can put this dial on a phone by the touchline and let the chime call half time. The 80 minute dial covers the whole match if you would rather see both halves on one face.
Up one step is 45 minutes, the class period and the football half. A forty-minute video sits on the card, and the timers page lists the whole range.

A radial timer draws the countdown as 20 concentric rings, one for each twentieth of the duration. Rings empty one by one, outermost first, so a glance shows how far along you are without reading a digit.
The timers here are free online countdown timers. Run several at once, take one fullscreen, or pop one out picture-in-picture to float over other apps. Each chimes at zero and keeps counting in a background tab. Any timer exports as a video.
Yes. The countdown follows the clock, so it stays on time while you work in another tab and still chimes at zero. The picture-in-picture popout keeps a small dial in view the whole way.
