Wickr is a messaging platform designed to give control over security to users

Where is the source? I can see your patents listed, but no links to your source code.

It's not open source.

I don't like Wickr's UI (on iOS), which is why I started using Threema (which offers some unique features, too).

Also not open source (just as an FYI to anyone reading this).

Threema uses NaCl, which is open source: https://nacl.cr.yp.to/

Trustworthy sums this app up.
