Yet another end-to-end encryption chat app, however, with post quantum cryptography (the NTRU library) resistant encryption.
Quantum computing threatens the confiedntiality of several asymmetric algorithms, i.e. Shor's algorithm. Post quantum cryptography uses asymmetric algorthims that are resistant to quantum attack, see wikipedia page here
Name for the application was chosen for the following:
What do vampires (and also probably cats) not like...
A Werewolf. Thus the chat app that protects you from Vampire Hacker Cats with end to end post quantum encryption is Werewolf Chat.
