## About app and us 

the Another Instant Messenger is not a messenger,
> don't believe the words.


we just offer you a standardized xmpp-client with predicted features which work equally on all platforms.\
in our clients we have realized pure XMPP and you won't step on a hedgehog unexpectedly when you communicate with another xmpp client or server.


because you buy our open-sourced bitcoin,\
we decided to offer you to buy our open-sourced messenger.\
ha-ha joke.\
it's free, really. GPLv3, whatever.


for Android, it's just an improved fork of Conversations,\
for iOS, it's our development from scratch,\
for Desktops we're polako [looking](xmpp:xmppclient-dev@conference.another.im). for devs.


all necessary XEP's was realized by Conversations devs but we added a cherry on top of this.\
on the server side we are offering free to use Prosody server,\
just connect to [another.im](xmpp:xmppclient-dev@conference.another.im), but we are encouroge you to don't trust us, self-host.

OTR encryption is also supported as 'secret chats' due to otr has been designed for one-time sessions and the concept of 'secret chats' fully corresponds to the idea of the OTR.

also you can just download <a href="https://dev.narayana.im/narayana/anotherim">the source code</a>, compile it and install.

only those who seeks will realize the way to pay us,\
we can offer you additional server-side features and some telecommunication magic on our <a href="https://narayana.im">narayana.im</a>

### XMPP Features

another.im works with every XMPP server out there. However XMPP is an
extensible protocol. These extensions are standardized as well in so called
XEP's. another.im supports a couple of these to make the overall user
experience better. There is a chance that your current XMPP server does not
support these extensions; therefore to get the most out of another.im you
should consider either switching to an XMPP server that does or — even better —
run your own XMPP server for you and your friends. These XEP's are:

* [XEP-0050: Ad-Hoc Commands](http://xmpp.org/extensions/xep-0050.html) lets to interact with gateways
* [XEP-0065: SOCKS5 Bytestreams](http://xmpp.org/extensions/xep-0065.html) will be used to transfer
  files if both parties are behind a firewall (NAT).
* [XEP-0163: Personal Eventing Protocol](http://xmpp.org/extensions/xep-0163.html) for avatars and OMEMO.
* [XEP-0191: Blocking command](http://xmpp.org/extensions/xep-0191.html) lets you blacklist spammers or block contacts
  without removing them from your roster.
* [XEP-0198: Stream Management](http://xmpp.org/extensions/xep-0198.html) allows XMPP to survive small network outages and
  changes of the underlying TCP connection.
* [XEP-0215: External Service Discovery](https://xmpp.org/extensions/xep-0215.html) will be used to discover STUN and TURN servers which facilitate P2P A/V calls.
* [XEP-0237: Roster Versioning](http://xmpp.org/extensions/xep-0237.html) mainly to save bandwidth on poor mobile connections
* [XEP-0280: Message Carbons](http://xmpp.org/extensions/xep-0280.html) which automatically syncs the messages you send to
  your desktop client and thus allows you to switch seamlessly from your mobile
  client to your desktop client and back within one conversation.
* [XEP-0308: Last Message Correction](https://xmpp.org/extensions/xep-0308.html) allows you to edit last message as well as retract it
* [XEP-0313: Message Archive Management](http://xmpp.org/extensions/xep-0313.html) synchronize message history with the
  server. Catch up with messages that were sent while another.im was
  offline.
* [XEP-0352: Client State Indication](http://xmpp.org/extensions/xep-0352.html) lets the server know whether or not
  Conversations is in the background. Allows the server to save bandwidth by
  withholding unimportant packages.
* [XEP-0363: HTTP File Upload](http://xmpp.org/extensions/xep-0363.html) allows you to share files in conferences
  and with offline contacts.
* [XEP-0461: Message Replies](https://xmpp.org/extensions/xep-0461.html) provides support of native replies, which also works in many transports (gateways) as well
* [XEP-0364: Current Off-the-Record Messaging Usage](https://xmpp.org/extensions/xep-0364.html) is also supported as 'secret chats' due to otr has been designed for one-time sessions and the concept of 'secret chats' fully corresponds to the idea of the OTR.
