Free Online Pomodoro Timer

The Pomodoro Technique breaks your work into focused 25-minute intervals separated by 5-minute breaks. After four focus sessions, you take a longer 15-30 minute break. ScreenTimer’s Pomodoro timer handles the entire cycle automatically with a beautiful circular progress ring and session tracking dots.

Fully Configurable Intervals

The default 25/5/15 split works for most people, but you can customize all three durations to match your personal rhythm. Some users prefer 50-minute focus blocks with 10-minute breaks. Others find 15-minute sprints more effective. Adjust the values and the timer adapts instantly.

Automatic Phase Transitions

When a focus session ends, the timer automatically switches to the break phase and vice versa. After the number of sessions you configure (default: 4), it triggers a long break instead of a short one. Session dots track your progress visually. You can also skip any phase manually with the Skip button.

Why Pomodoro Works

Research shows that the Pomodoro Technique reduces cognitive fatigue compared to unstructured work sessions. The fixed intervals make starting feel manageable and create a sustainable rhythm that carries you through an entire workday. Combined with our browser tab title display, you always know how much focus time remains without switching away from your work.

Timer with Breaks — Automatic Work and Rest Intervals

Looking for a timer with breaks that automatically alternates between focused work and rest periods? ScreenTimer’s Pomodoro timer does exactly this. Set your preferred work duration and break length, and the timer handles all transitions automatically. No manual restarting, no watching the clock. The browser tab title shows your remaining time so you can work in another tab and still see when your break is coming. Whether you call it a Pomodoro timer, a focus timer, or simply a timer with breaks, the core idea is the same: structured intervals produce better results than open-ended work sessions.

Tabata Timer — 20/10 Interval Training Preset

Screen Timer includes a built-in Tabata timer with the exact protocol from the original research: 20 seconds of maximum effort work followed by 10 seconds of rest, repeated for 8 rounds totaling 4 minutes. One click on the Tabata 20/10 preset starts the interval timer immediately, with automatic phase switching between work and rest, distinct audio cues at each transition, and a round counter tracking your progress. The work phase displays in amber and the rest phase in green, so you can read your current status from across the room during intense exercise.

Interval Timer with Custom Work and Rest Rounds

Beyond the Tabata preset, the interval timer supports fully customizable tabata times, HIIT protocols, and any work-rest ratio you need. Set work periods from 5 to 300 seconds, rest periods from 5 to 300 seconds, and anywhere from 1 to 50 rounds. Popular configurations include HIIT 30/30 for fat burning, HIIT 45/15 for muscular endurance, and 60/60 for aerobic base building. The timer with breaks alternates automatically between effort and recovery phases, playing a sound at each transition so you can focus entirely on your workout, study session, or any timed activity that benefits from structured intervals.

Yes. All three durations are fully configurable between 1 and 120 minutes. You can also adjust how many sessions trigger a long break. Settings apply instantly without restarting.

Does the Pomodoro timer automatically switch between focus and break?

Yes. When a focus session ends, the timer automatically transitions to a break and vice versa. After your configured number of focus sessions, it switches to a long break instead of a short break. You can also skip any phase manually.

Is a Pomodoro timer online better than a phone app?

A browser-based Pomodoro timer avoids the distraction of opening your phone, requires no installation, and works identically across all devices. The countdown appears in your browser tab title so you can monitor it while working in another tab.

What is the difference between the Pomodoro timer and the Interval timer?

The Pomodoro timer follows the structured Pomodoro Technique with session counting, automatic long breaks, and a progress ring. The Interval timer is simpler: it alternates between work and rest for a set number of rounds without session tracking. Use Pomodoro for productivity and studying, Interval timer for HIIT and Tabata workouts.
