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, 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.
* 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

Good try but...

Ghostiery and similar programs have been deliberately barred by Apple - which loves to play both sides of the datatheft crisis, claiming (and refusing to discuss taken) that it has really good encryption, while not allowing (as required under the Microsoft Internet Explorer decision) the ability to run with Tor or a full version of Firefox, while erasing its own browser from the system.
While Apple execs know there are companies that will crack open an i-phone for anyone with the $$s, it plays the We are So Honest game by announcing it will not do the job requested by ignorant police organizations.
So, here’s a program that claims not to collect anything much, and only gives what’s collected to folks who say real nice that they won’t let things escape, telling you to use a leaky product on an iPhone using a program unavailable because it doesn’t want Real Firefox or Tor available.
So claims of security just cannot be true.
I wish I were wrong about this, but what we need is some way to force Apple into allowing full PGP, if not RSA to run on its hand-held platforms.

Sounds Great!

Unfortunately I’m not really much of an advanced tech in any ay shape or form and find a lot of advanced tech mumbo-jumbo painfully confusing even though I find many types of advanced technology somewhat interesting as well as I usually have or try to use it the best and most up to date stuff when I can regardless of if I even know what I’m doing! Lol! With that being said, when I don’t necessarily understand something all that well I try to at least learn where or what the reputable resources are and The Tor Project is one regarding privacy/security so the fact that they support ChatSecure and list it on their site with direct links to download it means it should be pretty good for secure chatting purposes so once I begin getting more familiar with it I can add more about it!
