The one thing that Signal provides that is above and beyond Wickr is support for very simplistic encrypted calling. This also provides transparency in assuring that the intentions of Open Whisper Systems don’t change or become malicious. It is also open source, which allows everyone to view and validate that the application is working exactly as it is being marketed to work. Signal is very simple to use and provides a level of encryption that is top notch A+ grade and usable for all kinds of conversations. This really gives the application a level of trust that goes beyond its competitors in the same field like Wickr, Telegram, WhatsApp, or Facebook Messenger. They are the encrypted texting and calling application used by many and advocated for by big name people in the security/privacy industry like Edward Snowden, Matthew Green, and Bruce Schneier.


Open Whisper Systems had originally created separate apps for encrypted calling and encrypted messaging called TextSecure and RedPhone back in 2010 but they have since combined the two services into one app called Signal. Signal is marketed on the Open Whisper Systems website as “Privacy that fits in your pocket”.
