       Kaidan is a user-friendly and modern chat app for every device. It uses
       the open communication protocol XMPP (Jabber). Unlike other chat apps,
       you are not dependent on one specific service provider.

       Kaidan does not have all basic features yet and has still some
       stability issues. Current features include audio messages, video
       messages, and file sharing.
