Native on iPhone, iPad, Mac, and Apple Watch, with widgets and on-device Apple Intelligence. THE EISENHOWER MATRIX - Do — Urgent & Important: handle these first - Schedule — Important, Not Urgent: plan ahead - Delegate — Urgent, Not Important: hand off - Delete — Neither: let it go TASK MANAGEMENT - Quick add with quadrant, workspace, due date, notes, and links with auto-fetched titles - Drag between quadrants, or into Notes, Mail, and Messages as text - Backlog for undecided tasks, Archive for finished ones - Calendar of due and completed tasks - Daily reminder for today's due and overdue tasks SIRI & APPLE INTELLIGENCE - "Add a task to iomatrix" — Apple Intelligence turns a sentence into structured tasks, on device - Say several tasks at once; quadrant, due date, and workspace are inferred - Find and complete tasks by voice; every action works in Shortcuts - Without Apple Intelligence, your phrase is still saved as a task WORKSPACES - Separate work, personal, and projects, and filter the whole matrix by one - 10-color palette; archive a workspace when the project wraps - Three workspaces free; more with Pro HEATMAP & WIDGETS - GitHub-style completion heatmap that fits any screen and scrolls back two years - Widgets: matrix summary, quadrant lists, 2×2 grid, and heatmaps, including an extra large size that fills a Home Screen page - Lock Screen widgets and Apple Watch complications IOMATRIX PRO — ONE-TIME PURCHASE Everything above is free.
