Lumen is a modern, minimalist focus and time-tracking app that shines a light on where your time really goes.

Most to-do lists only tell you what you need to do—they don't show you how your day actually unfolded or why certain tasks keep dragging on. Lumen combines clean task management with effortless session tracking and start-count analytics, helping you spot distractions, reduce context-switching, and align your daily effort with your real priorities.

KEY FEATURES

• Effortless One-Tap Time Tracking
Track every task on a clean, tactile card. Tap the round button to start and stop your focus timer whenever you work.

• "Where Your Time Went" Dashboard
See your active task count, top focus task, and a live breakdown of how your tracked time is distributed across your workload.

• Start-Count & Fragmentation Detection
Lumen doesn't just measure duration—it counts how many times you start and stop each task. High start counts with short sessions highlight fragmented focus and frequent interruptions, helping you switch to deeper, uninterrupted work blocks.

• Actionable Focus Insights & Coaching Nudges
Filter your history by Today, This Week, This Month, All Time, or any Custom Date Range. Get plain-language coaching nudges tailored to your work patterns to build better focus habits.

• Flexible Task Organization
Switch seamlessly between a single-column drag-and-drop list and a compact 2-column grid view. Sort tasks by Custom Order or by Target End Date, and move completed tasks to the bottom with a single tap.

• Personalized Appearance
Work comfortably day or night with System, Light, and Dark modes, plus custom accent colors that personalize your charts, highlights, and controls.

• Local-First Privacy & CSV Export
Your tasks and time logs stay privately stored on your device—no account or cloud sign-up required. Export your complete task summaries and session history to CSV anytime for your own records or spreadsheets.

HOW TO GET THE MOST FROM LUMEN
1. Keep your active task list short and intentional.
2. Start the timer every time you begin a task, and pause it the moment you switch away.
3. Watch your start counts—if a task has 5+ starts, try blocking out 25–45 minutes of uninterrupted focus.
4. Review your Focus Insights weekly to make sure your top-ranked tasks are the ones that matter most.
