Every timer on radialtimers.com lives on its own page, and this is the list. Each page lands on a timer of that length, ready to start, so the address is the shortcut: bookmark the ones you use, or send a class, a stream, or a study group straight to the right one. All of them draw time the same way, as twenty rings that empty as the minutes pass with the exact count underneath, and all of them are free with no account.
A fixed length is the common case, not the only one. On the front page you can type any length up to the 100-hour ceiling, build a cycle of named blocks, or open a room that puts a group on one clock. If you are not sure which length fits the job, the guides walk through the usual ones: sprints for studying and work, intervals for training, and how long everyday things really take.
The workhorses: a minute for a toothbrush, five for a break, twenty-five for a pomodoro sprint, ninety for a long block of deep work.
For the long haul: an exam, a work shift, an overnight bake, or a whole day counted down on one face.
Short and sharp: a rest between sets, a plank, a speed round in class, or a delicate tea.
Named for the job rather than the length, each of these opens with the right shape already built, cycles included: pomodoro sprints, HIIT and tabata rounds, a three-hour exam, a seven-minute egg.
Calendars rather than timers: a day count to a fixed date, figured from your own midnight so it is never stale.
Counting up instead of down, for the spans you do not know yet; laps freeze on the face where they happened.
