# 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](/help/recent-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.

You can collapse or expand the list of topics in a stream by tapping the

icon to the left of a stream name.
