HS Compendium is an app created to be a companion for the game, Hades' Star. It contains a number of useful tools, including an income calculator, a technology search, and a number of interactive charts and graphs.

The app also includes a built-in discord bot that allows you to share data and tech with your friends, and a built-in white star bot. The white star bot is used to plan and to battle against other players.

The app is not developed by Parallel Space, Inc., the company that developed the game, and is not affiliated with them in any way. Some of the information in the app is obtained from the official website and from other sources.
