Description by Joonhee Cho Written by the developer, not by AppBrain. Click to read.
iomatrix is an intuitive task management app built around the Eisenhower Matrix — the proven prioritization framework used by leaders worldwide. Organize your tasks into four quadrants based on urgency and importance, and focus on what truly matters.


THE EISENHOWER MATRIX

Prioritize with clarity using four quadrants:
- Do: Urgent & Important — handle these first
- Schedule: Important but Not Urgent — plan ahead
- Delegate: Urgent but Not Important — hand these off
- Delete: Neither Urgent nor Important — let these go


TASK MANAGEMENT

- Quick Add: Create tasks instantly with title, quadrant, and optional details
- Drag & Drop: Move tasks between quadrants or reorder within them
- Due Dates: Set deadlines with date and time reminders
- Notes: Add detailed notes to any task
- Links: Attach multiple URLs with auto-fetched titles
- Backlog: Park undecided tasks in a dedicated backlog area
- Archive: Browse completed tasks grouped by date


WORKSPACES

Organize tasks across different areas of your life:
- Create custom workspaces with unique colors
- Filter your matrix by workspace
- Archive workspaces when projects are complete
- 9-color palette for easy visual distinction


ACTIVITY HEATMAP

Visualize your productivity:
- GitHub-style heatmap showing daily task completion
- Per-workspace heatmaps with custom colors
- Summary statistics (total and last 30 days)
- Configurable week start (Sunday/Monday)


CROSS-PLATFORM

Seamlessly works across your Apple devices:
- iPhone: Full matrix view with drag-and-drop
- Mac: Native macOS app with menu bar widget
- Apple Watch: View, add, edit, and manage tasks from your wrist
- Widgets: Home screen, Lock Screen, and watch face widgets


SYNC & PRIVACY

- iCloud Sync: Your tasks stay in sync across all devices
- Privacy First: All data stored in your personal iCloud — no third-party servers
- Offline Ready: Works without internet, syncs when connected


WIDGETS

Stay on top of your tasks at a glance:
- Small: 2x2 quadrant count grid
- Medium: Horizontal summary with labels
- Large: Full card layout with task counts
- Lock Screen: Inline and rectangular accessory widgets
- Watch Face: Circular, rectangular, corner, and donut chart complications
