ChatSecure is a free and open source messaging app that features OTR encryption over XMPP. You can connect to an existing Google account, create new accounts on public XMPP servers (including via Tor), or even connect to your own server for extra security.

Unlike other apps that keep you stuck in their walled garden, ChatSecure is fully interoperable with other clients that support OTR and XMPP, such as Adium, Jitsi, and more.

ChatSecure only uses well-known open source cryptographic libraries to keep your conversations private. Other apps may make claims about 'military grade' security but, without publicly auditable source code and verifiable end-to-end encryption, you cannot be truly safe.

* XMPP with TLS certificate pinning.
* OTR for verifiable end-to-end encryption and forward secrecy.
* OMEMO for a mobile-friendly alternative to OTR.
* Tor integration for easy access to XMPP .onion services.
* SQLCipher to locally encrypt conversation logs.
* Free and Open Source:

Notifications broken


The notifications never come through. It's hard to see the point of a messenger without working notifications.

No more searching. Best xmpp app for ios


Subj says it all. It can connect through tor without any extra tweaks and external stuff or apps.

And it is free!

XMPP client for iOS


I am a big fan of Signal. It's my go-to...however it sufferers from cross-platform support. This app brings a secure XMPP client to iOS.
