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:

Great SMS app and works with Top VoIP service

Background refresh is on as well as notifications but not able to view any notifications unless I open the app

Issues, but handy

It’s encouraging to see development continuing recently. ChatSecure has much potential. But it has some perpetual bugs. Background refresh often fails or never works. Which makes using XMPP at all rather dicey. The UI could use some touch ups, with one issue being a lack of clarity over which group or contact belongs to which account. Also crashes and failures do not generate any messages, which makes it hard to tell if it is even working. Some work on these areas would be great. But when it works, ChatSecure does its job.

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?
