Pomodoro Timer with Statistics

Build a productivity-focused Pomodoro timer that helps users manage work sessions and track their focus patterns over time. This timer implements the proven Pomodoro Technique where users work for 25-minute focused sessions followed by 5-minute breaks, with longer 15-30 minute breaks after every 4 sessions.

What You'll Build:

Your application should allow users to start work sessions, automatically transition between work and break periods, and maintain detailed statistics about their productivity. Users can customize session lengths, pause timers when needed, and view their daily, weekly, and monthly productivity patterns.

Key User Stories:

• As a user, I want to start a 25-minute work timer and be automatically notified when it's time for a break
• As a user, I want to see how many pomodoros I've completed today and track my consistency over time
• As a user, I want to customize work and break durations to fit my personal productivity style
• As a user, I want to add task descriptions to my sessions so I can see what I accomplished
• As a user, I want visual and audio notifications that don't disrupt my workflow

Technical Implementation:

Focus on clean code organization with proper separation of concerns. Implement client-side data persistence and responsive design patterns. Consider progressive enhancement and accessibility best practices.
