ChatSecure Messenger

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.
Category Price Seller Device
Social Networking Free Chris Ballinger iPhone, iPad, iPod

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: https://github.com/chatsecure/chatsecure-ios

feels like a beta. hoping it keeps improving.

i want to love this app. xmpp is good but apps are lacking. and this one has potential. but some frustrations: - often crashes on startup or hangs with a white screen - no search? - it’s clunky to get to your contact list - there isn’t much differentiation between users in group chats so it’s hard to see who wrote what at first glance. - i would like to customize colors and chat room icons pluses: - honors system default font size - notifications work - messages are sent and received reliably - open source i really hope there are updates in the future!


Crap
Play's a lot

I’ve been using this app for work for about 6 months and it has never works properly. IE crashes, when I send messages they get scrambled. And sends me error messages multiple times a day. I would recommend a different one to use.

No longer works for me

It was excellent while it still worked, but now it silently fails to send messages through my local ejabberd. It took me a few days to realize it wasn't working.


excellent!

opensource and supports jabber! in new version (4.3.0) messages keep disappearing and appearing - difficult to chat (using iphone x)


Best xmpp client around
Borisattva

Encrypted, easy to use, and in today's subscription plan world full functionality and a donate button. This app should be your go to for xmpp

Kelvin chanky

App used to work, but no longer. It automatically crashes upon opening when it is about to ask for my passphrase. I just deleted this junk.


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?

This app is beautifully made. It gives me a jabber client on ios, and it's the best I've found. It's got a pretty niche selection of services, but it does it's job extremely well. And it's free! Thank you developer for making this gem and giving it away.
