Settings guide
Configurable intervals:
| Setting | Default | Typical range |
|---|---|---|
| Work session | 25 min | 20–50 min |
| Short break | 5 min | 3–10 min |
| Long break | 15 min | 15–30 min |
| Sessions before long break | 4 | 3–6 |
Adapting the interval length: The 25-minute default is based on Cirillo's original research. Some people find 50-minute work intervals with 10-minute breaks more natural — this "double Pomodoro" approach fits better with tasks that require longer ramp-up time. Experiment with what matches your focus duration.
Ambient sound: Select a background sound at the start of a work session. The sound plays only during work intervals and pauses during breaks. Ambient sound is particularly useful in open offices where external noise is unpredictable.
Do not disturb: Consider enabling your OS's do-not-disturb mode for the duration of a Pomodoro. Notifications are the primary enemy of the technique — they break the interruption-free interval that is the core of its effectiveness.
Format comparison
vs the Forest app / Focus@Will / other paid focus apps: Paid focus apps add gamification (growing virtual trees), curated music playlists, and cross-device session syncing. These are legitimate features for some users. A browser-based Pomodoro timer provides the core mechanics — timed intervals, automatic transitions, session counting — for free, without an account or app installation.
vs a simple countdown timer: A countdown timer counts down from a set duration. A Pomodoro timer automates the full cycle: work interval → short break → work interval → long break after N cycles. You could replicate this with a countdown timer by manually resetting it each cycle, but the Pomodoro timer does this automatically, which removes one more friction point from the technique.
vs the Pomodoro Technique app (official Cirillo): The official apps by Francesco Cirillo's studio cost money and are designed for the strict implementation of the technique. A browser-based tool is adequate for the core practice without cost.
How it works
Configure your intervals (optional)
Adjust work session length, break duration, and number of sessions before a long break. The defaults (25/5/15) are standard.
Start a session
Press Start. The timer counts down the work interval. When it ends, a gentle alert sounds and the break timer begins automatically.
Work through the cycle
The timer alternates work and break intervals automatically. After four sessions, a long break follows. Your session count accumulates in the history display.
About this format
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the 1980s. The structure is simple: work for 25 minutes without interruption, take a 5-minute break, and repeat. After four work intervals (four "Pomodoros"), take a longer break of 15–30 minutes.
The method works because it makes cognitive work time-boxed and finite. Instead of "I need to finish this report," the task becomes "I will work on this report for the next 25 minutes." The break is non-negotiable — it prevents the diminishing returns of sustained focus without rest. The session counter builds a concrete record of productive time, which is satisfying in itself.
This timer automates the cycle: it transitions automatically from work sessions to short breaks and from short breaks back to work. After four sessions, it switches to a long break. You do not need to set and reset — the cycle runs itself. Ambient sound options (white noise, rain, café background) fill the work intervals without requiring a separate app or tab.
Session history tracks your completed Pomodoros over the current sitting, so you can see how much focused work you have accumulated. Configurable interval lengths let you adjust the standard 25/5 structure to 50/10 or any other split that matches your cognitive rhythm.
