Xabber
Xabber is an open-source XMPP client for Android with multi-account support. Light and secure, with OTR support, Xabber is currently the most popular XMPP client on Google Play. When we started development of this project, usability was our number one priority. Our ambition was to create best possible chatting experience on any mobile platform while supporting many popular extensions to XMPP standard, preserving compatibility and interoperability. We believe to have succeeded in this: Xabber features an attractive, easy to use and highly customizable interface with lots of grouping options that help users arrange their chat buddies exactly as they please.
Our second priority was security. A few years ago it wasn't as important as it is today, but now it's hard to overestimate importance to chat with someone without being spied upon. Built-in OTR support allows Xabber users to escape any possible wiretapping that might come from some sinister organisations. It is also possible to use XMPP via TOR connection, wich adds another layer of security for Xabber users.
