Pomodoro Timer
Immersive focus timer with ambient sounds, Flowtime mode, and session tracking. Stay in the zone.
You focused for 0 minutes. Take a proportional break.
How to Use This Pomodoro Timer
Click Start or press Space to begin a 25-minute focus session. When the timer ends, you'll hear a chime and the session counter advances. After four focus sessions, you'll get a longer break. Adjust focus and break durations in the Settings panel.
For a distraction-free experience, press F to enter immersive mode. Choose from six CSS-generated backgrounds — no images loaded — and toggle ambient sounds to create your ideal focus environment.
What Is the Pomodoro Technique?
The Pomodoro Technique was developed by Francesco Cirillo in the late 1980s. It breaks work into intervals — traditionally 25 minutes — separated by short breaks. Each interval is called a "pomodoro." After four pomodoros, you take a longer break of 15–30 minutes. The method helps maintain focus by creating urgency within each interval and guaranteeing rest between them.
Research suggests that working in focused bursts with planned breaks reduces mental fatigue and improves sustained attention. The fixed time constraint also helps combat procrastination — committing to just 25 minutes feels manageable even when a task feels overwhelming.
Flowtime Mode
Flowtime is an alternative to the rigid Pomodoro structure. Instead of a fixed countdown, the timer counts up while you work. When you decide to stop, the timer calculates a proportional break — roughly one-fifth of your focus time. This approach is better suited for tasks that require deep concentration, where a 25-minute interruption could break your flow.
Switch between Pomodoro and Flowtime using the tabs at the top. Both modes track sessions and contribute to your daily statistics.
Ambient Sounds
Choose from seven ambient sounds to set the mood. Brown noise is generated procedurally using the Web Audio API, while rain, cafe, fireplace, wind, wave, and stream play high-quality audio loops. You can mix up to two sounds simultaneously and adjust individual volumes.
Focus Tracking and Streaks
Every completed session is saved to your browser's localStorage. The dashboard shows today's session count, total focus minutes, and your current day streak. A 7-day heatmap visualizes your recent activity. Session data older than 30 days is automatically cleaned up. No data ever leaves your browser.
Frequently Asked Questions
Does the timer work in the background?
Yes. The timer uses a combination of setInterval and timestamp comparison to maintain accuracy even when the browser tab is inactive. The tab title updates with the remaining time so you can monitor progress from your taskbar.
Can I customize the timer durations?
Yes. Open the Settings panel to adjust focus duration (5–90 minutes), short break (1–30 minutes), and long break (5–45 minutes). Your settings are saved to localStorage and persist across sessions.
What keyboard shortcuts are available?
Space starts or pauses the timer. R resets the current session. F toggles immersive mode. M mutes all sounds. 1 and 2 switch between Pomodoro and Flowtime modes.
Is my data private?
Completely. Everything runs in your browser. Session data is stored in localStorage on your device. No accounts, no servers, no tracking of your focus sessions. The only external request is Google Fonts for typography.
