Overview
52/17, flowtime, and custom intervals. Match your timer to how your brain actually focuses.
Study one subject for the block, then take the break away from the same screen.
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.
