To group iPhone Reminder lists, drag one list onto another or tap Edit Lists and choose Add Group. Run the SORT Rule next: scan your lists, organize into three groups, reduce pins to three, and test your default list.

If you already use tags or project lists but still scroll past fifteen names to find Work, this is for you.

What every guide agrees on (table stakes)

Apple Support and the top search results all teach the same mechanics:

  • Drag one list onto another to create a group.
  • Or tap ..., choose Edit Lists, then Add Group.
  • Pin up to nine lists above the fold for quick access.
  • Swipe left to delete a group while keeping the lists inside.

That covers the taps. It does not tell you which lists belong together, how many groups you actually need, or what to do when groups, tags, and sections all sound like "organization."

Groups vs tags vs sections: which layer fixes your mess

Apple gives you three organizers. They solve different problems.

  • Groups sort lists in the sidebar. Use them when you have more than eight lists and only three feel active this week.
  • Tags sort tasks across lists. Use them when you ask "what can I do with a phone right now?" See our context lists on iPhone guide for the four-tag setup.
  • Sections sort tasks inside one list. Use them when a single project has phases, like Ideas, Active, and Done. See our sections vs subtasks guide for the LAYER Rule.

Your takeaway: groups shrink the sidebar, tags shrink your next-action view, sections shrink one crowded list.

The gap: the SORT Rule

Most tutorials stop at "drag Work onto Personal." You end up with one giant group and pinned lists you forgot about.

The SORT Rule is a ten-minute cleanup you run when the sidebar feels heavy:

  1. Scan. Count every list. Mark any list you have not opened in thirty days as Archive candidate. Mark any list you open daily as Pin candidate.
  2. Organize. Create three groups max: Work, Home, and Someday. Drag lists into the group that matches where the tasks live, not how urgent they feel.
  3. Reduce pins. Unpin everything. Pin only three: Today (built-in), your main active work list, and one personal list like Errands. Apple allows nine pins. Three is enough.
  4. Test default list. Open the list you capture into most often. Tap ..., Show List Info, set Default List. Add a test reminder. Confirm it lands in the right bucket before you close the app.

Run SORT once per season, or whenever you add a fourth new list in one week.

Walkthrough: Alex with fourteen lists

Alex has lists named Q3 Report, Client A, Client B, Kitchen Reno, Groceries, Taxes 2025, Side Project, Reading List, Gift Ideas, and five more from old jobs. The sidebar takes four swipes to reach Groceries.

Minute 1-3 (Scan): Alex opens Reminders, taps ..., Edit Lists. Client A and Client B have no tasks dated this month. Reading List and Gift Ideas have not been opened since spring. Those four move to Someday.

Minute 4-7 (Organize): Alex taps Add Group, names it Work, and checks Q3 Report only. A second group Home gets Kitchen Reno, Groceries, and Taxes 2025. Someday holds Client A, Client B, Reading List, Gift Ideas, and the old job lists. Side Project stays ungrouped because it is the only active side hustle.

Minute 8-9 (Reduce pins): Alex unpins everything except Today, Q3 Report, and Groceries. Work and Home groups collapse. The sidebar now shows three pins, one Side Project list, and two collapsed groups.

Minute 10 (Test): Alex sets Q3 Report as Default List on Monday morning. She adds "email design team about footer copy." It lands on Q3 Report, not Groceries. Friday evening she switches default to Groceries before the store run.

Bold takeaway: collapsed groups beat a flat list of names you never tap.

Where Divux fits

Reminders groups work until you want tasks beside your calendar and a focus timer on the same screen. Divux keeps lists, calendar blocks, and habits in one daily view. Build the same three groups as saved filters, pin your active project, and timebox the next task without hopping apps.

Common mistakes (and the fix)

  • Grouping by urgency instead of life area. "Urgent" is not a group. Urgent tasks belong on Today or get a flag. Groups hold stable buckets like Work and Home.
  • Pinning every list you might need. Nine pins is the Apple max, not a goal. If everything is pinned, nothing stands out. Keep three pins and trust collapsed groups for the rest.
  • Using groups when tags are the real fix. If your problem is "show me every phone call across projects," tags and Smart Lists solve that. Groups only tidy the sidebar. Build contexts first if tasks are scattered, not lists.
  • Deleting a group and losing lists. When you delete a group, tap Keep Lists. Lists move to the top level. You are removing the folder, not the tasks inside.
  • Skipping the default list test. A clean sidebar still fails if Siri drops new captures into the wrong list. Always add one test reminder after you change default list.

Frequently asked questions

How do you create a reminder group on iPhone?

Open Reminders, tap the three-dot menu, choose Edit Lists, then tap Add Group. Name the group, select the lists to include, and tap Done. You can also drag one list onto another in the sidebar to create a group instantly. Both methods work on iCloud lists.

What is the difference between reminder groups and tags on iPhone?

Groups organize lists in the sidebar, like Work and Home folders. Tags organize individual tasks across lists, like #calls or #errands. Use groups to hide list clutter. Use tags to see every matching task in one Smart List view. Most people need both, but in that order.

How many lists can you pin in iPhone Reminders?

Apple allows up to nine pinned lists. Pin only the three you open daily: usually Today, your main work list, and one personal list. Park everything else inside collapsed groups so the sidebar stays scannable. More pins means more scrolling, not less.

Open Reminders, run SORT on your sidebar, and collapse one group before you add another list. A sidebar you can scan in one glance beats a perfect taxonomy you never maintain.
