Tertiary Planner
Read full descriptionHide full description
Tertiary Planner is a fast, private to-do and planner app for iPhone, iPad and Mac. Type or speak what you need ā "Lunch with Sam tomorrow at 1pm" ā 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 ⢠One Planner page with To-Do and Appointment tabs, each filterable by your lists ⢠Capture bar at the bottom ā type or dictate, and the assistant drafts and saves the entry; Undo reverts it ⢠Apple Intelligence on-device intent understanding (with an on-device fallback) ⢠Voice capture using native iOS speech recognition ⢠Your own lists and sub-lists ā create, rename, pin, reorder and nest them ⢠Assign items to people; items added in someone's list go to that person ⢠To-Do priorities ā Critical, High, Medium or Low; Critical and High are pinned automatically ⢠Pin anything to the top; drag to rearrange everything by hand ⢠Smart views: All Tasks, Pinned, Today and Upcoming show your own queue ⢠Upcoming ā everything with a date, broken down by day, with anything overdue on top ⢠Calendar ā a month view with each day's appointments written into the day, plus a List view ⢠Meeting links ā paste a Google Meet, Zoom or Teams link and tap Join on the appointment ⢠Singapore public holidays marked on the calendar ⢠Today's appointments ā a morning summary and an alert just before each appointment starts ⢠Advance reminders ā a notification before anything with a date is due (1, 3 or 7 days ahead) ⢠Optional mirror of appointments into your system Calendar (EventKit only) ⢠Search across titles, notes, assignee and list names ⢠Duplicate check ā spots the same title on the same day and offers to archive the extras ⢠Check off an item and it is automatically archived; restore anytime ⢠iCloud sync ā your items stay up to date on every device signed in to your iCloud ⢠Light, Dark or System appearance, with a choice of accent colours PRIVACY Your data belongs to you.

Reflow

Your day never goes exactly to plan. Reflow is the first planner that expects that. Most planners hand you a perfect schedule at 8am and guilt by noon. Miss one block and the whole day collapses ā so you stop opening the app. Reflow works the other way: when life shifts, your plan shifts with it. One tap, and you're back on track. THE TIMELINE THAT HEALS ITSELF ⢠Running 20 minutes late? Reflow previews how the rest of your day can flex ā you confirm with one tap. ⢠Locked blocks (meetings, appointments, school pickup) never move. Ever. ⢠Flexible blocks reshuffle around them automatically. ⢠See the new plan as ghost blocks before anything changes. You stay in control. SPEAK YOUR PLAN ⢠Say it like you'd say it to a friend: "Gym at 5, then groceries, dinner with Alex at 8." ⢠Reflow turns it into timeline blocks as drafts you confirm ā nothing is ever saved without your OK. ⢠Voice is processed entirely on your device. Audio never leaves your phone. REMINDERS WITHOUT GUILT ⢠Gentle escalation that works with your brain, not against it ā a nudge, then a firmer one, only if you need it. ⢠Missed something? No red badges, no streaks broken, no shame. Reflow simply asks: reinsert it today, move it to tomorrow, or let it go. ⢠Quiet hours mean your evenings stay yours. MADE FOR ADHD BRAINS ⢠Time blindness support: your day as one visual timeline, with a live "now" line. ⢠A Live Activity keeps your current block on the Lock Screen and in the Dynamic Island. ⢠Unlimited colors, 400+ symbols, and every emoji to make blocks unmistakably yours. ⢠Calm, dark-first design. No clutter, no dashboards, no productivity theater. YOUR DATA STAYS YOURS ⢠Sign in with Apple protects account and subscription access. Your plans live on your device, synced privately through your own iCloud. ⢠No ads. No data selling. No tracking. REFLOW PRO Your first two distinct planning days are free. After that, Reflow offers a 14-day subscription trial ā $9.99/month or $49.99/year. Subscriptions renew automatically and can be cancelled anytime in Settings. Payment is charged to your Apple ID account. Trial eligibility is determined by Apple. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://devbiok.github.io/reflow-site/privacy.html Reflow was built with one belief: you were never the problem ā rigid plans were. Welcome to the planner that finally flexes.
