comiXchat

Even the most boring yap turns awesome with comiXchat.
It's quite simple, actually: as you chat, your conversation turns to a rich comics.
comiXchat is today's most expressive messaging app and is guaranteed to bring fun back into chatting. It puts your chat buddies and you into an animated world as if a professional cartoonist was sitting there with you. With it's advanced emotion control, no one will miss the context of your messages again.

It works like any other chat with private and group chats, attachments and multimedia support. You have a growing selection of avatars to select from and amazing scenery backgrounds assuring there's no two drawings alike. Best of all, when you won't be able to keep those hysterical outcomes to yourself, comiXchat will turn your chat into a comics strip and share it directly through email, facebook or anything you want.

VentureBeat though "there’s a glut of mobile messaging apps all vying for attention... But comiXchat, has a unique spin"
and UpStart called it "Imagine WhatsApp on LSD"
