Apple Reminders
Have the reminders Italic drafts land in Apple Reminders on your iPhone.
Italic adds reminders to Apple Reminders, so they alert you wherever your other reminders do. Chat on any device and your workflows can draft a reminder, but only the Italic iPhone app can add it. There's no account to connect.
Turn it on
Open Apple Reminders
In the Italic iPhone app, open Profile → Connectors → Apple Reminders.
Allow access
Choose Allow access to Reminders. If you declined before, choose Allow in iPhone Settings and turn on access there.
Pick a default list
Under Default list, pick where reminders go. Until you pick one, they go to your default list in Reminders.
Make a reminder
Say "Remind me to buy milk at 6" or "Turn this into a to-do". Italic drafts the reminder, and approving it (Add Reminder on the iPhone) adds it to your default list. Name a list to use another one: "Add milk to my Groceries list" goes to Groceries when you have a list with that name. The draft shows where it's going, such as "Reminders · Groceries".
Italic can add reminders with notes, a due date and a list. It can't change or delete your reminders.
From the web, your Mac and workflows
On the web and the Mac, a reminder draft has Add reminder, Edit and Discard. Edit changes its title, notes, list and due date. Once you approve it, Italic wakes your iPhone, which adds it without Italic being opened, and Italic tells you which list it used. A locked iPhone adds it once you unlock it.
Workflows can make reminders with the Create reminder action. Its List picks from the lists your iPhone or Mac reported; until one has, type a list's name. A reminder from a workflow that runs automatically is added the same way, in the background on your iPhone, as long as you've already allowed access to Reminders. Its Lock Screen activity reads "Adding the reminder…", and asks you to open Italic only if your iPhone couldn't add it.
With App 321 or earlier, your iPhone adds these reminders the next time Italic opens.
Apple Reminders is in Connectors on the web and the Mac too. Its page has its permission and shows your default list, which you can pick only on the iPhone.
Permission
Apple Reminders has the same Ask every time, Allow without asking and Off choices as other apps. See Connectors. With Off, Italic doesn't add reminders in chat or in workflows.
