Overview
25-minute focus blocks are not just a trend. Learn how to structure deep work with proven intervals.
Write the task before you start the 25 minutes. When the block ends, stand up for the break even if the sentence is unfinished.
How to use it
- Open Pomodoro Timer.
- Write the task in the label, start the block, and leave chat and extra tabs until it ends.
- Keep Online Timer or Focus Timer for a second phase.
Good to know
A focus timer does not make a vague task clearer. If you cannot say what “done” looks like, fix that before you press start.
