💡 Inspiration

Like many developers, I struggled with procrastination and context switching. After exploring productivity techniques, the Pomodoro Technique stood out for its simplicity and effectiveness. I thought: What if I could build a single-page app that not only tracks my Pomodoro sessions but also lets me manage tasks and monitor global time zones for team collaboration?
That question became TimeMaster.


🚀 What It Does

TimeMaster is an all-in-one productivity web app that empowers users to manage their time more effectively through:

  • ⏱️ Pomodoro Timer – Uses the 25:5 work-break cycle with Start, Pause, and Reset.
  • 🌍 World Clock – Displays live time for New York, Mumbai, London, Tokyo.
  • 📝 To-Do List – Add/delete tasks with optional deadlines.
  • 🌙 Dark Mode – Toggle for better usability in different lighting.
  • 🔁 Tab Navigation – Smooth, reload-free tool switching.

No logins, no distractions—just open and start mastering your time.


🛠️ How We Built It

We used:

  • HTML for page structure
  • Tailwind CSS for responsive and clean UI
  • Vanilla JavaScript for real-time logic and UI behavior

Each feature is modularized with separate files for HTML, CSS, and JS to maintain clarity.


🧗 Challenges We Faced

  • Real-time updates for multiple world clocks
  • Ensuring Pomodoro timer runs even if tab focus changes
  • Smooth tab navigation without libraries
  • Designing responsive layout for all devices
