Description by PISO 13, Inc. Written by the developer, not by AppBrain. Click to read.
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 your Mac, and it all stays in sync with iPhone and iPad.

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 click away.
• Meeting Planner for agendas, decisions, and next steps.

NOTES AND JOURNALS
• Rich notes with fonts, colors, tags, and your own custom sections.
• Sketches and handwriting made with Apple Pencil on iPad sync straight to your Mac.
• Journals with 25 covers to choose from, plus a guided Gratitude Journal.

ACROSS ALL YOUR DEVICES
• Widgets for today's tasks, your mission, your values, and daily quotes.
• Add a task with Siri.
• iCloud sync across Mac, iPhone, and iPad.

MAKE IT YOURS
• Planner themes, including seasonal ones.
• Task-complete sounds and rewards for finishing what you planned.
• Color-coded categories and repeating rules with advanced options.

The core planner is free. Opus One Pro adds cloud sync across all your devices, weather, attachments (images, PDFs, audio), categories, repeating rules, Goals, Siri, and themes. One subscription covers Mac, iPhone, and iPad on the same iCloud account. Available yearly or monthly.
