ZenTrack: Productivity Evolved

Master Your Flow. Design your best day with an AI-powered, high-performance task management system.

ZenTrack is a minimalist yet powerful MERN stack application designed for users who value focus. Unlike standard to-do lists, ZenTrack introduces the Zen Score —a dynamic productivity metric that weights tasks by priority and punctuality to provide real-time performance feedback.

Core Features

The Zen Productivity Engine ( Logic )

  const calculateStats = (allTasks) => {
  const completedList = allTasks.filter(t => t.completed);
  const total = allTasks.length;
  const pending = total - completedList.length;

  // 1. Calculate the Raw Zen Score
  const rawZenScore = completedList.reduce((acc, task) => {
    let points = 10;<img width="1895" height="855" alt="Screenshot 2026-04-09 140016" src="https://github.com/user-attachments/assets/92dea08b-1083-4161-9b7a-21bd2a188b73" />

    const weights = { high: 2.5, medium: 1.5, low: 1.0 };
    let multiplier = weights[task.priority] || 1.0;

    if (task.dueDate) {
      const isOverdue = new Date(task.dueDate) < new Date();
      multiplier *= isOverdue ? 0.8 : 1.2;
    }
    return acc + (points * multiplier);
  }, 0);

  const finalScore = Math.round(rawZenScore);

  // 2. Determine Level based on the score we just calculated
  const getZenLevel = (score) => {
    if (score === 0) return { label: "Resting", color: "text-slate-400" };
    if (score < 50) return { label: "Awakening", color: "text-amber-500" };
    if (score < 150) return { label: "Flow State", color: "text-indigo-500" };
    return { label: "Zen Master", color: "text-purple-500" };
  };

  const level = getZenLevel(finalScore);

  // 3. Return everything including the level info
  return {
    total,
    pending,
    completed: completedList.length,
    zenScore: finalScore,
    velocity: total ? Math.round((completedList.length / total) * 100) : 0,
    level // Now this is available in your stats object!
  };
};

const stats = calculateStats(tasks);

• Weighted Scoring: Tasks are not created equal. Earn 30pts for High, 15pts for Medium, and 10pts for Low priority tasks.
• Punctuality Bonus: Integrated date-logic rewards you with a 20% bonus for on-time completion and applies a 20% penalty for overdue tasks.
• Dynamic Zen Levels: Progress from "Resting" to "Zen Master" based on your persistent score

🤖 AI-Planner

• AI Planner/ Suggestion Engine: Integrated generative AI to break down complex projects into actionable roadmaps.

• Intelligent Task Generator: Transform a single goal into a structured sub-task list automatically.

• Predictive Workflows: Suggests the next task to tackle based on priority and urgency.

Technical Highlights

• Atomic State Management: Uses MongoDB's $inc operator to handle score updates, preventing race conditions during rapid user interaction.
• Persistent Auth: Secure JWT-based authentication ensures your Zen Score and task history follow you across all devices.
• AI-Ready Planner: Integrated AI input fields for roadmap generation (LLM-ready).
• Glassmorphic UI: A premium, dark-mode-first interface built with Framer Motion for fluid animations and Lucide React for iconography.

System Architecture

ZenTrack follows a decoupled client-server architecture:

1. Frontend: A Vite-powered SPA that handles "Optimistic UI" updates for immediate feedback.
2. Backend: A RESTful API that acts as the "Source of Truth" for scoring logic and data validation.
3. Persistence: Cross-session data storage ensuring user stats are retained post-login.
