Three hours drawn as 20 rings, one emptying every 9 minutes. For a practice SAT, a bar-course block, or any timed sitting, one glance places you in the exam without the tick of a clock.
The point of a practice exam is that it feels like the real one, and the clock is most of that feeling. A three hour sitting is the shape of many bar and professional papers, some university finals, and the total sitting time of several standardized tests once breaks are counted. Set this page going as the paper is turned over, take it fullscreen with the f key, and the room has a clock that everybody reads the same way: 20 rings, one emptying every 9 minutes, and nothing else on the screen.
Because a ring is nine minutes, the dial converts into a pacing plan without arithmetic. A paper with six equal questions gets three rings and a bit each, so when the fourth ring is gone you should be leaving question one. A paper in three sections gets roughly seven rings a section. Decide the ring budget before you start, write it at the top of the page, and glance at the dial only when you finish a question.
Sections with different lengths are best run as a Cycle: open Cycles, add one block per section with its official length, and the chime marks each turnover the way an invigilator would.
For a study group or a class, one screen at the front is enough, and a projector makes the rings readable from the back. If people sit in different places, a Room gives every device the same countdown from one link, so a phone on each desk shows the same nine-minute rings.
Pausing to look something up turns a mock into homework. Starting the clock late, after reading the paper, hides the minutes that reading costs on the day. Running practice papers only at full length is another one: for the first attempts, time a single section and get the pacing right there before spending an afternoon. More on this in countdowns and deadlines.
Yes. Run it fullscreen on a projector or a shared screen and the rings read from the back row.
Yes, a clear double chime at zero, even from a background tab. The rings stay silent until then.
Pick another duration from the timers below, or set a custom one on any dial.
Add it as a browser source in OBS; the background stays transparent. Change t for any length.
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. Run several timers at once, take one fullscreen, or pop one out picture-in-picture to float over other apps. Every timer keeps counting in a background tab, and any timer exports as a video. No download, no sign-up.
Its dial 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.
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.
Yes. Any timer exports as an MP4 or a transparent WebM of the whole countdown, up to 4K and 60 fps, in 16:9, vertical, or square.
Yes. In OBS, add a browser source pointing at radialtimers.com/overlay?t=25m and a transparent dial counts down over your scene. Change t for any length, like 90s or 3h.
As many as you need. Each timer gets its own dial and runs on its own, which suits interval workouts, several dishes on the stove, or a room of activity stations.
