Formula

Tool description

A Pomodoro timer helps you focus by alternating work and break intervals. This version defaults to 25/5, supports custom durations, and runs entirely in your browser.

How to use

Set work and break minutes (or keep 25/5).
Click Start to begin the work interval.
Use Skip to jump to the next interval.
Use Reset to stop and return to the start of the current interval.

Why it’s useful

Helps reduce procrastination by making work “small and timed”.
Builds consistency with planned breaks.
Supports deep work with fewer context switches.

Use cases & interpretation

Homework sessions: run 3–4 work intervals, then take a longer rest.
Reading: use shorter work blocks (e.g., 15/5) to stay engaged.
Exam prep: use longer work blocks (e.g., 45/10) for practice tests.

FAQs
