Yoyo User Guide

Yoyo is a desktop chat-style app for managing daily tasks optimised for use through command line prompts, while complemented by a Graphical User Interface (GUI). If you prefer typing commands rather than interacting with a GUI, Yoyo can manage your tasks faster than traditional GUI apps.
