Work for 25 minutes, then take a 5-minute break. After 4 sessions, take a longer 15-minute break.
What is the Pomodoro Timer?
The Pomodoro Timer is a focus management tool based on the Pomodoro Technique: work in structured 25-minute intervals (Focus sessions) followed by short 5-minute breaks, with a longer 15-minute break after every four sessions. Standard productivity apps with cloud accounts track your session history on external servers. This tool runs entirely inside your browser tab with no server communication.
Your daily session count and total focus minutes are stored in your browser's localStorage, so your stats persist across page refreshes. They reset automatically at the start of each new day.
How to Use the Pomodoro Timer
Starting a focus session involves these steps:
- Select your session mode from the mode buttons: "Focus" (25 min), "Short Break" (5 min), or "Long Break" (15 min).
- Click "Start" to begin the countdown. The browser tab title updates to show the remaining time.
- Work on your task for the full duration without switching to distracting tabs.
- When the timer ends, the tab title shows a coffee icon and an optional beep plays via the browser's Web Audio API.
- Click "Start" on a Short Break mode to rest for 5 minutes, then return to Focus.
- After 4 Focus sessions, take a Long Break. Your session count in the Stats Card updates automatically.
- Toggle the "Sound: ON/OFF" button to enable or disable the completion beep.

Frequently Asked Questions
Yes! Our pomodoro timer uses modern browser logic to keep the countdown active even if you navigate to another tab. However, we recommend keeping this tab visible in a separate window or pinned for the best results and to see the visual "Pulse" alert.
To ensure high productivity and prevent "Planning Procrastination," we use the scientifically-validated Pomodoro standards: 25 minutes for focus and 5/15 minutes for breaks. Custom durations may be added in a future update.
The tool uses three indicators: 1. The tab title updates with a coffee icon. 2. A "Visual Pulse" animation starts on the page. 3. If enabled, a discrete beep sounds via the Web Audio API. This ensures you catch the signal without being startled.

After completing 4 focus sessions (a "Pomodoro set"), it is highly recommended to take a 15-20 minute Long Break. This allows for deep cognitive recovery and prevents mental fatigue during high-intensity workdays.
