+# Inbox
+
+The **Inbox** is the default view in the Zulip mobile app. It's a great way to
+get an overview of all the unmuted conversations where you have unread messages,
+excluding [inactive streams](/help/manage-inactive-streams).
+
+The **Inbox** view shows your unread direct message conversations, followed by
+all topics with unread messages, grouped by stream. The list of streams is
+sorted alphabetically, with [pinned streams](/help/pin-a-stream) at the top.
+

+1. Tap the **Inbox**
+   (<img src="/static/images/help/mobile-inbox-icon.svg" alt="inbox" class="mobile-icon"/>)
+   tab in the bottom left corner of the app.
+
+{end_tabs}
+
+!!! tip ""
+
+    You can collapse or expand the list of topics in a stream by tapping the
+    **collapse**
+    (<img src="/static/images/help/mobile-expand-less-icon.svg" alt="inbox" class="mobile-icon"/>)
+    or **expand**
