Conversations is a modern, open-source instant messaging client for Android devices, built upon the widely adopted XMPP protocol. Created with a strong emphasis on privacy and battery efficiency, it offers a robust alternative to proprietary platforms. By utilizing a decentralized network, users can communicate freely without being locked into a single ecosystem. Security is a foundational pillar of Conversations, featuring state-of-the-art end-to-end encryption out of the box. It fully supports OMEMO, an encryption standard ensuring messages remain completely private across multiple devices. The app seamlessly handles file transfers, image sharing, and voice messages while maintaining rigorous security standards. Beyond individual messaging, Conversations excels in facilitating group communication through Multi-User Chat. It offers advanced features like message archiving, typing indicators, and read receipts. Because it is fully open-source, the codebase is transparent, making it the preferred choice for privacy advocates seeking a secure communication tool.

Lark is an all-in-one collaboration suite for teams that want meetings, chat, shared documents, calendars, and lightweight business workflows in one place. It suits growing companies and distributed teams seeking a connected daily workspace.
