How we grade them
| 3.4GPAOpus OneVery good | 3.8GPAStructuredExcellent | |
|---|---|---|
| Value for money | AThe US App Store lists Pro at $4.99 and $39.99, sold monthly or yearly, without saying which price is which. If $39.99 is the year, that's about $3.33 a month against a typical $8. One subscription covers iPhone, iPad and Mac. | AThe US App Store lists Pro at $2.99, $6.99 and $7.99 a month and from $9.99 to $39.99 a year, or $99.99 once for life. Even the top yearly price is under half what a typical planner costs over a year. Prices change by region, and Structured publishes no price list. |
| Free plan and trial | BThe core planner is free, but Daily Tasks, Master Tasks and Daily Notes are limited, and the listing doesn't say by how much. Sync between your devices, goals and repeating tasks are all Pro. | BFree for good, with the timeline, an inbox, subtasks, notes, notifications, widgets and sync. That's a real planner. But repeating tasks, calendar import, Reminders import and the AI all need Pro, and a day planner without your calendar in it is a tight deal. |
| Features | AA page per day with A/B/C priorities and your calendar beside it, a master list, five planner views, goals tied to daily tasks, journals, a meeting planner and an Eisenhower matrix. That's a full paper planner and then some. | AOne timeline for tasks and events with day, week and month views, an inbox for things not yet scheduled, imports from Google Calendar, Outlook, Apple Reminders and Microsoft To Do, repeating tasks, Replan for the ones you missed, and an AI that drafts your day or scans a paper timetable. |
| Ease of use | A4.7 from about 960 App Store ratings. It's laid out like a paper day planner, and you move tasks, events and goals by dragging them. | A4.8 from about 167,000 App Store ratings, which is a huge crowd to keep happy. Your day is a single coloured line you read top to bottom. No manual needed for that. |
| Platforms and integrations | CiPhone, iPad, Mac and Apple Watch, with Apple Calendar, Google Calendar and Apple Reminders hooked in. All Apple, though. No Android, Windows or web version. | AiPhone, iPad, Mac, Apple Watch, Android and a web app, kept in step by Structured Cloud. It pulls in Google Calendar, Outlook, Apple Reminders and Microsoft To Do. No Windows app, and the web version doesn't have every feature of the phone apps yet. |

Worth knowing
Opus One
- 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.
Structured
- The vendor publishes no price list. Pro pricing depends on region and currency and is shown in the app or app store.
- Recurring tasks, calendar import, Reminders import, Replan and Structured AI all require Structured Pro.
- There is no Windows app. Structured Web runs in a browser but does not yet have every feature of the mobile apps.
- Structured Web needs an internet connection and a Structured Cloud sync account.
