About the Pomodoro Timer
A free, browser-based Pomodoro timer with customizable focus and break durations, session tracking, audio cues, screen wake lock, and an auto-start toggle.
What it is
The Pomodoro Timer runs focus-and-break sessions entirely in your browser. You set the focus duration, short-break duration, long-break duration, and how many focus sessions come before the long break — then press Start. The timer counts down each phase, plays distinct audio cues at every transition, and tracks your session count throughout the day.
It defaults to the classic Pomodoro protocol: 25 minutes of focused work, a 5-minute short break, and a 15-minute long break after every four sessions. But every value is adjustable, so you can match it to your own rhythm — shorter or longer focus blocks, more frequent long breaks, or a custom cycle length.
Everything runs in your browser. No data is sent to a server, stored, or logged anywhere.
The Pomodoro Technique
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s. The core idea is simple: divide your work into short, fixed-length intervals (pomodoros) separated by breaks. The structure forces you to commit to one task per interval, start without overthinking, and take rest before fatigue builds.
A standard cycle: 25 minutes of focused work → 5-minute short break → 25 minutes → 5-minute break → 25 minutes → 5-minute break → 25 minutes → 15-minute long break. Then repeat. The long break resets your attention fully before you begin the next cycle. The timer handles the counting so you can focus on the work.
Key features
Audio cues via Web Audio API
At each phase transition the timer plays distinct audio signals — ascending tones to start a focus session, descending tones at each break, and a longer chime for the long break. These use the Web Audio API so they fire reliably even when the screen is locked or the tab is in the background.
Screen Wake Lock
On supported browsers the timer requests a screen wake lock when you press Start, keeping the display on throughout your session. The lock is released automatically when you pause, skip, or reset. On browsers that don't support it, the timer still runs and audio cues still fire.
Customizable durations and cycle
Set focus length (1–120 min), short-break length (1–60 min), long-break length (1–120 min), and sessions per cycle (1–20) to match your workflow. Settings lock while a session is running so you can't accidentally change them mid-task.
Auto-start next phase
With auto-start on, the timer moves straight from focus to break and break to focus without any input. With it off, it pauses at each transition so you can gather yourself before pressing Resume — useful when you need a moment to switch tasks or context.
Session tracking
A session counter shows your completed pomodoros and your position in the current cycle, so you always know how many focused blocks you've done and when the next long break is coming.
Skip and reset
Skip moves immediately to the next phase — useful when you finish early or need to jump ahead. Reset clears the session entirely so you can start fresh. Both are available any time the timer is not in its initial idle state.
Who it's for
Students and studying
Structure revision sessions with timed focus blocks and scheduled breaks. The cues signal when to stop — so you don't have to watch the clock.
Deep work and writing
Writers, coders, and analysts use pomodoros to protect long stretches of concentration. Each interval becomes a commitment to stay on one task.
ADHD and focus challenges
Short, defined intervals make tasks feel less overwhelming and the built-in breaks reduce the resistance to starting. Many people find the structure helps sustain focus that would otherwise drift.
Remote work and productivity
Working from home makes it easy to blur work and breaks. Pomodoros create a visible, audible boundary between focus time and rest — which is hard to ignore.
