How to Use the Pomodoro Timer

Choose a preset session (Classic 25/5, Deep Work 50/10, Study 25/5/25/15, or Sprint 15/3) or build your own custom session using the Session Builder. Add focus and break phases, set the duration for each, and choose a notification sound. Click “Start Session” and the timer counts down automatically, transitioning between focus and break phases with sound alerts. Use the task list below to track what you’re working on.

What Is the Pomodoro Technique?

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The core idea is simple: work in focused intervals (traditionally 25 minutes) separated by short breaks (5 minutes). After four focus intervals, take a longer break (15-30 minutes). The technique works because it creates urgency (a countdown), prevents burnout (mandatory breaks), and makes large tasks feel manageable (just 25 minutes at a time).

Research in cognitive psychology supports this approach. Studies show that brief diversions from a task can dramatically improve focus on that task for prolonged periods. The human brain wasn’t designed for hours of unbroken concentration — periodic breaks actually increase overall productivity and creativity.

Tips for Effective Focus Sessions

During focus phases, close all unnecessary browser tabs and silence your phone notifications. If a distracting thought pops up, write it down on your task list to address later — don’t act on it now. During breaks, stand up, stretch, and look away from your screen. Avoid social media during breaks, as it tends to extend well beyond the allotted time. Track your completed sessions to build momentum and accountability.

Frequently Asked Questions

Does the timer work in background tabs?

Yes. Unlike many web-based timers, ours uses a Web Worker that keeps running accurately even when you switch to another browser tab. The sound alert will play when each phase ends.

Can I customize the session length?

Absolutely. The Session Builder lets you create any combination of focus and break phases with durations from 1 to 120 minutes. You can also choose different notification sounds for each phase.

Is 25 minutes the best interval for everyone?

Not necessarily. Some people focus better with longer intervals (50 minutes for deep work) or shorter ones (15 minutes for tasks you’re dreading). Experiment with different settings to find what works for you — that’s why we included the Session Builder.
