MattCha

MattCha is a native Mattermost chat client for iPhone, iPad, and Mac that connects to the server you choose.

Sign in to your Mattermost server and keep up with team conversations in channels, direct messages, and threads. MattCha focuses on a clean SwiftUI experience with native navigation, unread counts, message search, reactions, attachments, voice recordings, Markdown rendering, and local caching for recently viewed workspace content.

Features include:

• Connect to a Mattermost server with username/password or a personal access token
• Browse teams, public channels, private channels, direct messages, and group messages
• Read, send, delete, and reply to messages
• Record and send voice messages for quick audio replies
• View and manage threaded conversations
• Add and remove emoji reactions
• Search channels and messages
• Upload, download, open, and save supported attachments
• See unread counts and mark channels as read
• Use native iPad and Mac layouts with a sidebar, chat view, and optional thread pane
• Log out to clear the local session, cached workspace state, and stored credentials

MattCha does not provide a Mattermost server, create Mattermost accounts, or host workspace data. Your account, messages, files, permissions, retention rules, and moderation are managed by the Mattermost server you choose to connect to.
