    Riot Android

    Riot Android

    A glossy Matrix collaboration client for Android

    Riot Android is the original Android client for the Matrix network — a decentralized, secure communication protocol — that enables users to send end-to-end encrypted messages, join rooms, conduct voice and video calls, and interact across federated communities without relying on centralized servers. As the predecessor to Element X, Riot Android laid the groundwork for mobile access to Matrix while providing advanced features like threaded replies, rich media handling, room moderation, and custom notification controls. It integrates tightly with Android’s native platform capabilities, offering background sync, push notifications, and account management while keeping user cryptographic keys secure on the device for privacy. Users appreciate Riot’s ability to join public or private communities hosted across different Matrix servers, making it useful for both personal and organizational communication with interoperability at its core.
