C-simple is a basic and easy-to-use (“c-simple” means phonetically “it’s easy !” in french) mobile interface to the C-lightning Lightning Network daemon. It uses an API hosted on top of the daemon and a mutual authentication with x509 certificates, to make a secure connection possible from a mobile application.

You can find the API code (made with RPyC) in the c-simple/ directory, and the application code (made with Kivy) int client/ directory. Both are entirely written in Python.
