Signal is a protocol, there are other implementations of the client, for instance; Silence[1]. Which is a fork of TextSecure (now Signal) that aims to keep the SMS encryption that TextSecure removed for a variety of reasons. "Protect your communication in transit and on your phone. Silence[2] (formerly SMSSecure) is a full replacement for the default text messaging application: all messages are encrypted locally and messages to other Silence users are encrypted over the air."
