Boogie Chat is a FREE XMPP/Jabber chat client for iPad and iPhone. With Boogie Chat you can join multiple chat rooms to talk with several of your friends or colleagues simultaneously.
The app supports both single user chat and multiple user chat rooms (MUC XEP-0045), and image upload through XEP-0363 (with Dropbox option for servers that do not support image uploads directly)
With Boogie Chat companies can connect to their own internal chat services. Many compatible Jabber servers are OpenSource and can be found freely from the internet allowing for a near zero cost private chat service. The Boogie Chat client is free with an optional in-app purchase to permit multiple accounts and multiple chat rooms.
