What is the Pomodoro Technique?
The Pomodoro Technique was created by Francesco Cirillo for a more productive way to work and study. The technique uses a timer to break down work into intervals — traditionally 25 minutes in length — separated by short breaks. Each interval is known as a pomodoro, from the Italian word for "tomato", after the tomato-shaped kitchen timer Cirillo used as a university student.
Features
- Customizable work/break interval durations to suit your preference
- Color transition animations to shift mood between work and rest modes
- Audio notification at the end of each timer period
- Session counter to track completed Pomodoros
- Fully responsive — works on desktop and mobile
- Clean, distraction-free minimal UI
How to Use It
- Add the tasks you want to work on today
- Set your estimated Pomodoros (1 = 25 minutes of work)
- Select a task to focus on
- Start the timer and focus for 25 minutes
- Take a 5-minute break when the alarm rings
- After 4 Pomodoros, take a longer 15-30 minute break
What I Learned
Building this app deepened my understanding of React hooks (useState, useEffect, useRef) for managing timer state, interval cleanup on component unmount, and browser audio API integration. The color transition animations taught me how to apply dynamic CSS class changes in React for smooth UI transitions.
