Opus One is a real day planner, not another to-do app. Each day gets its own page — tasks with A/B/C priorities, your schedule, and notes — on a planner that looks and feels like paper. Plan on iPhone, iPad, and Mac, and it all stays in sync. YOUR DAY ON ONE PAGE • Daily Tasks with A/B/C priorities, status, notes, and alarms. • A schedule that shows your Calendar events alongside your tasks. • Drag a task onto the schedule — with task durations, the end time fills in automatically. • Daily Notes with photos, PDFs, checklists, and audio. • Today's weather and a daily quote, right on the page. PLAN BEYOND TODAY • Master Tasks: everything on your mind in one list, no due date required. • Goals with timelines, photos, and progress you can see. • Roles: review the areas of your life each week so nothing important gets crowded out. • Mission, Values, and Vision pages to keep the big picture one tap away. • Meeting Planner for agendas, decisions, and next steps. NOTES AND JOURNALS • Rich notes with fonts, colors, tags, and your own custom sections. • Sketch and handwrite with Apple Pencil. • Journals with 25 covers to choose from, plus a guided Gratitude Journal.

To make things even more delightful, you can take formatted notes, attachments and drawings on both your events and tasks inside the app. ● Effortless Scheduling Sorted³ helps you easily set a schedule for your day, and decide what’s important, what can wait, and what you reasonably have time for. You can use Auto Schedule to figure out what you can realistically get done in a day. Instead of feeling underproductive, Sorted³ helps you set attainable goals that you can accomplish. ● Built-in Flexibility Even when properly scheduled in advance, days don’t always go as planned! Sorted³ is built with that flexibility in mind to adjust to your changing schedule.
