About

Tertiary Planner

Read full description

Tertiary Planner is a fast, private to-do and planner app for iPhone, iPad and Mac. Type or speak what you need β€” "Lunch with Sam tomorrow at 1pm" β€” and the on-device assistant words it nicely and saves it as an appointment or a to-do, straight into your list. On supported devices it uses Apple Intelligence, running entirely ON DEVICE, to understand your intent and word your items clearly. On other devices the same on-device parsing (Apple's Natural Language and Speech frameworks) does the job. Either way, nothing you type or say ever leaves your device to any third party. FEATURES β€’ One Planner page with To-Do and Appointment tabs, each filterable by your lists β€’ Capture bar at the bottom β€” type or dictate, and the assistant drafts and saves the entry; Undo reverts it β€’ Apple Intelligence on-device intent understanding (with an on-device fallback) β€’ Voice capture using native iOS speech recognition β€’ Your own lists and sub-lists β€” create, rename, pin, reorder and nest them β€’ Assign items to people; items added in someone's list go to that person β€’ To-Do priorities β€” Critical, High, Medium or Low; Critical and High are pinned automatically β€’ Pin anything to the top; drag to rearrange everything by hand β€’ Smart views: All Tasks, Pinned, Today and Upcoming show your own queue β€’ Upcoming β€” everything with a date, broken down by day, with anything overdue on top β€’ Calendar β€” a month view with each day's appointments written into the day, plus a List view β€’ Meeting links β€” paste a Google Meet, Zoom or Teams link and tap Join on the appointment β€’ Singapore public holidays marked on the calendar β€’ Today's appointments β€” a morning summary and an alert just before each appointment starts β€’ Advance reminders β€” a notification before anything with a date is due (1, 3 or 7 days ahead) β€’ Optional mirror of appointments into your system Calendar (EventKit only) β€’ Search across titles, notes, assignee and list names β€’ Duplicate check β€” spots the same title on the same day and offers to archive the extras β€’ Check off an item and it is automatically archived; restore anytime β€’ iCloud sync β€” your items stay up to date on every device signed in to your iCloud β€’ Light, Dark or System appearance, with a choice of accent colours PRIVACY Your data belongs to you.
