What's with the open source programm „TextSecure“? It's an alternative for WhatsApp and it's opensource (GPLv3). It encrypt messages as standard and features forward secrecy and deniability guarantees.
Furthermore, it gives an audit about Textsecure from the Ruhr University Bochum with the result: "Furthermore, we formally prove that—if our mitigation is applied—TEXTSECURE’s push messaging can indeed achieve the goals of authenticity and confidentiality."
