Chat Messaging App Light and Dark Theme is a Flutter UI project for building a messaging app interface with both light and dark modes. It includes multiple screens that cover the core visual flow of a chat application, starting with a welcome screen and moving into authentication and conversation views. The project is intended as a design and implementation reference rather than a complete messaging backend. It demonstrates how Flutter layouts can be structured for chat lists, message screens, onboarding, sign-in, and sign-up experiences. The dual theme support makes it useful for learning how to design consistent interfaces across different visual modes. It is best suited for Flutter learners and mobile developers who need a clean UI base for chat-style apps.

ChatSecure is a free and open source messaging app that features OMEMO encryption and OTR encryption over XMPP. You can connect to your existing Google accounts or create new accounts on public XMPP servers (including via Tor), or even connect to your own server for extra security. Unlike other apps that keep you stuck in their walled garden, ChatSecure is fully interoperable with other clients that support OMEMO or OTR and XMPP, such as Conversations (Android), CoyIM (Desktop), and more. ChatSecure only uses well-known open-source cryptographic libraries to keep your conversations private. Other apps may make claims about "military grade" security but, without publicly auditable source code and verifiable end-to-end encryption, you cannot be truly safe.
