Reading sprints and Pomodoro blocks
You sit down with a chapter or a stack of notes and want a clean 25 minutes of work. That length is the default focus block in the Pomodoro technique: pick one task, work until the bell, then take a short break. It is also a common reading sprint, long enough to get through several pages but short enough to stay sharp.
Other tasks that fit 25 minutes:
- A classroom quiz section or a short presentation slot.
- A set of rests between gym sets, if you are timing the whole circuit rather than one rest.
- A timed exam section, where each question gets a slice of the 25 minutes.
- A guided meditation session, which often runs 20 to 25 minutes.
The timer works from your computer's clock, not by counting ticks. That means it keeps honest time when the tab is in the background or the device sleeps. The display refreshes several times a second, and the tab title shows the remaining time so you can read it from another tab. A running timer survives a page reload on the same page, because the end time is stored in the browser for that tab.
