dol

dol is a notes app you write in markdown. Your notes live on your device, and you decide which server they sync through. ā Everything you would expect Live preview as you type. [[Wikilink]] autocompletion and backlinks. Search across titles and bodies. Find and replace inside a note. Nested folders and image attachments. ā Sync that goes nowhere else Your iPhone, iPad, and the Windows and Mac apps all see the same notes, and they travel through a CouchDB server you choose. Run your own or use a host ā either works. Setup takes about five minutes from the settings screen, and your password is stored only in the iOS keychain. ā Sync is optional Leave it off and your notes stay on this device. No internet connection needed. ā Import and export Bring in a folder of .md files you already have. Or go the other way: export every note and image as a single zip.
Tertiary Planner

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. All intelligence runs on your device. Items are stored on your device and synced only through your personal, private iCloud database, which only you can access ā we never see your data. No third-party AI services, no accounts, no tracking. Developed by Tertiary Infotech Academy Pte Ltd.

Verdict
The clearest difference is update cadence: Tertiary Planner at every 2 days against dol's every 8 days. dol's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
