ChatSecure - Encrypted Messenger

By Chris Ballinger

Open iTunes to buy and download apps.


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 to help bypass restrictive firewalls.
* SQLCipher to locally encrypt conversation logs.
* Free and Open Source:

Customer Reviews

Not a good hipchat (XMPP) replacement

The app initially will connect to the hipchat server but after closing and reopening the connection always fails with a xml syntax validation failure (for the connection that was just working)

Additionally it does not support groups / rooms and will only work (he first time it connects) to send 1:1 messages :-/
