24me vs Opus One

24me

• People who want events, to-dos and notes on a single mobile calendar
• Families sharing grocery lists, chores and events
• Anyone who wants traffic-based reminders to leave on time

Opus One

• 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

24me

• The store listings cover iPhone, iPad, Apple Watch, Android and Wear OS. Neither they nor the vendor's site mention a web, Mac or Windows app.
• Email to tasks, location-based reminders, nag alerts, timezone support and printing the schedule all need Premium.
• The App Store's in-app purchase list also shows items named 24me Pro from $9.99 to $99.99 with no billing period, and Google Play gives only a range of $7.99 to $64.99 per item.

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.

24me

One calendar for events, tasks and notes

Events, to-dos and notes are listed together on a calendar with several views, synced with Google Calendar, Microsoft Outlook, Exchange, Yahoo Calendar and Apple iCal.

To-do list with reminders

Tasks take color labels and multiple reminders and can be added by voice, including through Siri and Amazon Alexa. Turning an email into a task is part of Premium.

Notes and lists

Notes can hold text, photos, videos and voice recordings, cover things like shopping lists, and appear on the calendar next to events and tasks.

Smart alerts

Time-to-leave alerts follow traffic conditions, and there are weather alerts, birthday reminders and a summary of the next day's meetings and to-dos.

Conference call dialing

With a dial-in number and passcode entered in a meeting's location field, the app dials into the call without the codes being typed again.

Shared lists and events

Lists, tasks, events, reminders and notes can be shared with family members or colleagues and stay in sync for everyone taking part.

Opus One

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.

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.

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.

Goals, roles and mission

Goals have timelines and visible progress and can be linked to daily tasks. Separate pages hold life roles, a mission statement, values and vision.

Notes and journals

Notes take text, photos, PDFs, checklists, audio and drawings. Journals come with 25 covers and include a guided Gratitude Journal.

Eisenhower matrix and categories

Tasks can be shown in an Eisenhower matrix, sorted by priority or by color-coded category, and repeated with custom rules.
