How can I participate in a Chat?

To participate in a Chat, you will need to:

  • Be subscribed to a Substack.
  • Have the Substack Reader iOS installed.

Once a writer starts a thread, you can participate by tapping on the Chat icon on the Substack app. Substacks you subscribe to will appear showing the most recent threads.


Tap on a thread to start interacting with the writer and other readers. You can reply to any thread with text and/or an image as well as react to other readers' replies.


You can also tap on another reader's message to react or to leave a reply.


How am I notified about Chat?

You can select which Chat push notifications to receive. To turn off or turn on Chat notifications, follow these steps:

1. On the Substack iOS app, tap the Profile icon and then the Settings icon in the top-right corner.

2. Tap "Notifications" and on this screen, toggle on or off what push notifications you'd like to start or stop receiving.

  • New threads: When a writer you're subscribed to starts a new Chat thread.
  • Replies: When other readers leave a reply in a Chat thread.
  • Reactions: When readers emoji-react to your reply.


Who can see my replies?

Any subscriber of the publication will be able to see your reply in a Thread. If they react to your message, you'll see a notification in your Activity section (click on the bell in the top right corner of the app).

Tip: Don't see a thread? Check to see if you're on the latest version of the Substack iOS app and check your Library to see if the publication is listed under your Subscriptions.
