What Is the Pomodoro Tracker?
The Pomodoro Tracker takes the classic Pomodoro Technique and wraps it in a full productivity dashboard. Instead of just timing 25-minute sessions, it tracks every completed pomodoro across days and weeks, helping you see patterns in your productivity and build lasting habits.
At its core, you get the same proven cycle: 25 minutes of focused work, then a 5-minute break, with a longer 15-minute break after every 4 sessions. But the tracker adds session history with timestamps, a GitHub-style contribution heatmap showing your activity over the past year, daily goal tracking with progress rings, task categories with time distribution charts, and data export.
Everything runs entirely in your browser. Your session data is stored locally and persists between visits. No account, no server, no tracking. Just open the page and start focusing.
How to Use the Pomodoro Tracker
1. Name your task and pick a category. Type what you're working on in the text field and select a category (Work, Study, Personal, Creative, or Exercise). This feeds the time distribution chart so you can see exactly where your hours go.
2. Press Start or hit Space. The timer begins a 25-minute focus session by default. The progress ring fills as time passes. The browser tab title updates with the remaining time so you can work in another tab.
3. Work until the chime. When the session ends, you hear an audio chime and (if permitted) receive a browser notification. The session is logged automatically with start time, end time, duration, and task label.
4. Track your progress. Watch the daily goal ring fill, review your session history table, and check the heatmap to see your consistency over time. Use the weekly stats panel to compare against your personal best.
5. Export your data. Download a CSV of your entire session history for spreadsheet analysis, or copy a JSON snapshot of today's stats for your records or integrations.
Why Track Your Pomodoros?
A timer tells you when to stop. A tracker tells you how you're doing over time. Research on habit formation shows that visible progress is one of the strongest motivators for maintaining a new behavior. The heatmap creates the same satisfying streak effect that makes contribution graphs on coding platforms so addictive.
Category tracking reveals where your time actually goes versus where you think it goes. Most people are surprised by the gap. Seeing a pie chart that shows 3 hours on email versus 45 minutes on deep work is the kind of insight that drives real behavior change.
Daily goals create accountability without a boss. Setting a target of 8 pomodoros per day (about 3.3 hours of focused work) is achievable for most knowledge workers and represents a genuinely productive day. The progress ring gives you that dopamine hit every time you inch closer.
Frequently Asked Questions
How is this different from the Pomodoro Timer?
The Pomodoro Timer is a focused, single-session timer. This Pomodoro Tracker is a full productivity dashboard that persists your session history across days, tracks daily and weekly goals, shows a GitHub-style contribution heatmap, and lets you categorize tasks with pie chart breakdowns. Think of the Timer as a stopwatch and the Tracker as a fitness app.
Is my data saved between visits?
Yes. All session history, heatmap data, and settings are stored in your browser's localStorage. Your data persists across browser sessions and page reloads. No data is sent to any server. Clearing your browser data will erase your history, so use the CSV export to back up important records.
How does the productivity heatmap work?
The heatmap displays the last 365 days in a grid, similar to GitHub's contribution graph. Each square represents one day, and the color intensity shows how many pomodoros you completed: light green for 1-2, medium for 3-5, dark for 6-8, and darkest for 9 or more. Hover over any square to see the exact count.
Can I customize the timer durations?
Yes. Click the gear icon to adjust focus duration (1-120 min), short break (1-30 min), long break (1-60 min), sessions per cycle (2-10), and your daily goal (1-20). You can also toggle auto-start for the next phase so breaks and focus sessions begin automatically.
What export formats are available?
You can download a CSV file containing every completed session with timestamps, durations, task names, and categories — perfect for spreadsheet analysis. You can also copy a JSON snapshot of today's stats, session log, and settings to your clipboard.
