History

ChatSecure was originally released in 2011 and was the first iOS application to support OTR messaging. In 2012 ChatSecure was a partnership with The Guardian Project and the Gibberbot app was rebranded to “ChatSecure Android”. [10]

In late 2016, the Android branding partnership was closed, [11] [12] with ChatSecure Android becoming ‘Zom’, [13] and ChatSecure iOS remaining as ChatSecure. ChatSecure iOS remains in active development and is unaffected by this change. Version 4.0 was released on January 17, 2017. [14]
