Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 35 of the 69 other daily planner apps we grade
Opus One is a digital day planner for Apple devices that gives each day its own page, with prioritized tasks, a schedule showing calendar events, and notes. Beyond the daily page it keeps a master task list, goals, life roles, mission and values pages, and a meeting planner. The core planner is free; the Opus One Pro subscription adds iCloud sync across iPhone, iPad and Mac, along with goals, attachments and repeating rules.
To get you started, here are 9 things to know about Opus One, taken from its own pages and our grades.
It's laid out like a paper day planner, and you move tasks, events and goals by dragging them.
- 1
Best for a paper-style page for every day, on Apple
Opus One gives every day its own page, like a paper planner: tasks ranked A, B and C, your schedule and notes, with goals, life roles and a mission page around them.
- 2
What it costs
Paid plans start at $4.99 or $39.99 (US App Store; sold monthly or yearly, prices not labelled).
- 3
There is a free plan
The core planner is free, with limited Daily Tasks, Master Tasks and Daily Notes. Cloud sync, goals, attachments, categories, repeating rules and themes belong to Opus One Pro.
- 4
It runs on 2 platforms
iOS and macOS.
- 5
A page for each day
Each day has its own page holding tasks ranked by A/B/C priority, a schedule that shows calendar events next to the tasks, daily notes, the weather and a quote.
- 6
Master Tasks
A separate list for tasks that have no due date yet, kept apart from the daily pages until a place is found for them in the planner.
- 7
Planner views
Five planner views cover a day, a week or a month with the task list at the side. Tasks, events and goals are rescheduled by dragging and dropping them.
- 8
A 2.6 GPA, above 35 of 69
That is against the other daily planner apps we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
The plain part of Opus One you could make: tasks, calendar, notes, goals, daily notes and time blocking. What surrounds it you could not. The 3 things listed below take a company, not a weekend.

The report card
Best for a paper-style page for every day, on Apple
Opus One gives every day its own page, like a paper planner: tasks ranked A, B and C, your schedule and notes, with goals, life roles and a mission page around them. It's Apple only, the free plan caps daily tasks and notes without saying where, and sync between your own devices needs Pro, whose two prices aren't labeled monthly or yearly.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | The US App Store lists Pro at $4.99 and $39.99, monthly or yearly, without saying which price is which. Read the year as $39.99 and that's $3.33 a month, inside the cheaper quarter of this category. One subscription covers iPhone, iPad and Mac. |
| Free plan and trial | C | The core planner is free, but Daily Tasks, Master Tasks and Daily Notes are all capped and the listing never says by how much. Sync between your own devices, goals and repeating tasks are Pro, and there's no trial on record. |
| Features | B | It covers the whole job: a page per day with A/B/C priorities and your calendar beside it, a master list for undated tasks, five planner views, goals tied to daily tasks, journals, a meeting planner and an Eisenhower matrix. |
| Ease of use | B | 4.69 from about 960 App Store ratings, a shade under our line for an A on both counts. It's laid out like a paper day planner, and you move tasks, events and goals by dragging them. |
| Platforms and integrations | C | Apple and nothing else: iPhone, iPad, Mac and Apple Watch, with Apple Calendar, Google Calendar and Apple Reminders hooked in. No Android, Windows or web version, and the Reminders import only goes one way. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Opus One is for
- Fits if you want a page-a-day paper planner layout on iPhone, iPad and Mac
- Works for people who tie daily tasks to goals, life roles and a mission
Who it is not for
- Skip it if you use Android, Windows or the web, as it's Apple devices only
- Tight if you're staying free, because tasks and notes are capped and sync, goals and repeating tasks are Pro
- Watch out: the App Store lists Pro at $4.99 and $39.99 without saying which is monthly and which is yearly
- Not for you if you want to keep your Apple Reminders lists, since importing a task removes it from Reminders
- Skip it if you want to try Pro first, as there's no trial on record
Good to know
Good for
- People who like the layout of a paper day planner
- Linking daily tasks to goals, values and a personal mission
- Users who work only on iPhone, iPad and Mac
Worth knowing
- Apple devices only: iPhone, iPad, Mac and Apple Watch. The vendor lists no Android, Windows or web version.
- Cloud sync, goals, attachments, categories, repeating rules, weather and Siri all need the Opus One Pro subscription.
- The App Store lists two Pro prices, $4.99 and $39.99, and says the subscription is monthly or yearly without labelling which price is which.
- The Apple Reminders import is one-way: imported tasks are removed from the Reminders list.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of Opus One you could make: tasks, calendar, notes, goals, daily notes and time blocking. What surrounds it you could not. The 3 things listed below take a company, not a weekend.
What you could make
- Tasks, calendar, notes, goals, daily notes and time blocking: an app builder makes these well.
What you could not
- Apps for macOS and iOS that stay in step with each other.
- It plugs into other products, Apple Calendar, Google Calendar and Apple Reminders among them.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Opus One’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
