What notification grouping does

Notification grouping stacks your notifications by app instead of showing each one separately. When grouping is on, you'll see one notification from Messages, one from Email, one from Instagram — rather than five separate message notifications scattered across your lock screen. Tap the group and it expands to show all the individual notifications inside.

Apple introduced this feature because phones were drowning in notifications. Without grouping, your lock screen becomes unreadable within minutes. With it, you get a cleaner view and can decide which apps deserve your attention right now.

Key Takeaways

  • Notification grouping stacks multiple alerts from the same app into one expandable group, reducing clutter on your lock screen.
  • You can turn grouping on or off for individual apps, so Messages can be grouped while Slack stays ungrouped if that's what you prefer.
  • Grouping by time (recent notifications first) and grouping by app (all Messages together) are two different settings that work together.
  • If an app's notifications feel urgent, you can disable grouping for that app alone without affecting the rest of your phone.

How to turn notification grouping on or off

Go to Settings, then Notifications. Scroll down and tap the app you want to change. Look for the section labeled "Notification Grouping" — it will show three options: Off, By App, or Automatic.

Off means every notification appears separately. By App means all notifications from that app are grouped together. Automatic means iOS decides based on how you use the app — if you get a lot of notifications, it groups them; if you get a few, it might not.

Most people leave it on Automatic and only change individual apps. If you find yourself tapping into a group dozens of times a day, switch that app to Off. If an app's notifications feel less urgent, switch it to By App.

Grouped notifications versus time-based sorting

There's a separate setting that controls whether notifications are sorted by app or by time. Go to Settings, then Notifications, then scroll to the very bottom and look for "Notification Grouping." You'll see a toggle for "Stack" — this is what actually groups them.

If Stack is on, notifications are grouped by app. If it's off, they're sorted by time (newest first). You can have grouping on for individual apps but still see all notifications sorted by time across your lock screen. These two settings work independently, which confuses most people.

The practical difference: with Stack on, you see one Messages bubble even if you have ten unread messages. With Stack off, you see all ten messages listed separately but in time order. Most people find Stack on easier to scan.

When to disable grouping for a specific app

Disable grouping for apps where you need to see every notification at a glance. This usually means apps related to safety, money, or time-sensitive work: banking apps, calendar reminders, navigation, or messaging apps you use for work.

If you use Slack for work and need to see every mention when ready, turn off grouping for Slack. Your Messages app can stay grouped because you can afford to tap once to see all your texts. Your News app can stay grouped because you don't need to see every headline at once.

The trade-off is a busier lock screen. If you disable grouping for more than three or four apps, you're back to the original problem — too many notifications to read. Start with one app and see if it actually changes your behavior.

How grouped notifications appear on your lock screen

When grouping is on, you'll see the app name with a number showing how many notifications are waiting. Tap the group and it expands to show all of them. You can swipe left on individual notifications within the group to delete them, or tap one to open it.

On your home screen and in the notification center, grouped notifications look the same — one bubble per app with a count. The difference is mainly on your lock screen, where space is limited and clutter matters most.

If you have Do Not Disturb on, grouped notifications still arrive but they won't light up your screen or make a sound. When you turn Do Not Disturb off, you'll see all of them grouped together, which is why grouping helps when you've been away from your phone.

Grouping and notification sounds and badges

Grouping doesn't change how often your phone makes a sound or vibrates. If you get ten Messages notifications, your phone will alert you ten times whether they're grouped or not. Grouping only affects what you see on your lock screen, not how often you're interrupted.

App badges (the red circles with numbers) also work the same way. A grouped Messages notification will still show a badge with the total number of unread messages. Grouping is purely visual — it doesn't reduce the number of alerts, just how many bubbles you see.

If notifications from an app are interrupting you too much, the real solution is to change the notification sound and alert style in that app's settings, not to group them. Grouping helps you manage what you see; it doesn't reduce what's trying to get your attention.

Frequently Asked Questions

Does turning off grouping mean I'll get more notifications?

No. Turning off grouping only changes how they appear on your lock screen — you still get the same number of notifications. If you want fewer interruptions, you need to change the alert style or turn off notifications for that app entirely in Settings.

Can I group some apps but not others?

Yes. Each app has its own grouping setting. You can have Messages grouped, Slack ungrouped, and Email on Automatic all at the same time. Go to Settings, Notifications, tap the app, and change its individual setting.

What's the difference between "By App" and "Automatic"?

By App always groups notifications from that app together. Automatic lets iOS decide based on your usage patterns — if you ignore notifications from an app, iOS might stop grouping them. For most people, Automatic works fine.

If I have grouping on, will I miss important notifications?

No. Grouped notifications still arrive and still alert you. You just tap the group to see them all. If you're worried about missing something, turn off grouping for that specific app rather than all apps.

Does grouping work the same way on iPad?

Yes. iPad has the same grouping settings in Notifications. The main difference is that iPad has more screen space, so grouped notifications matter less — but the setting works identically.
