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:

Chat is pretty good ...but....


You guys have been marvelous really! I love Chat but this latest update crashes constantly!
The biggest problem Is when I scroll back through my texts and in the middle of that the whole thing crashes! What gives?

Buggy and bad notifications


Happy about the omemo support and whatnot, but on iOS 12 it seems like the app constantly crashes on other outright, or it just displays a blank screen for chats.

Additionally it seems to give multiple notifications per message? Some saying I have a message, some with a message.

Would love to see improvements!
