What's Inside

Everything you loved,
nothing you didn't.

Circul is a Flutter-built messaging app — real-time, and unabashedly retro in all the right ways.

💬
Direct Messages
One-on-one conversations with glossy chat bubbles, read receipts, pinned messages, and full message history search.
👥
Group Chats
Create named groups, invite friends, rename at any time. Unread badges keep you on top of every thread.
🏛️
Panels & Channels
Discord-style community spaces with named channels, categories, invite codes, and public/private visibility.
🟢
Live Presence
Online, Away, Busy, Offline — with a mood line under your name. Status updates propagate instantly over WebSocket.
🤝
Friend Requests
Send, accept, or deny friend requests the old-fashioned way. Your contacts list is curated, not algorithmic.
🖼️
Images & Avatars
Send inline images in any chat. Set a custom avatar and even a personal chat background that friends see when messaging you.
📌
Pinned Messages
Pin any message in a conversation or channel so important info never gets scrolled away. Unpin anytime.
✏️
Text Formatting
Bold, italic, underline — plus @mentions that notify the right people in group and channel messages.
🔄
Auto-Update
Built-in update manifest and release distribution. The app checks for new versions and downloads them silently.
Authentic Sound Design

You'll recognise
every single one.

Circul has a full, named sound system — each moment has its own audio cue, just like the good old days.
