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.

Verdict

The call

The clearest difference is monetization model: Weekly Planner at free with in-app purchases against Opus One's subscription. Weekly Planner also leads on ratings volume (15K vs 954). Opus One's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 18.0). On price, rating, review sentiment and update cadence there is nothing between them.
