Naviary on youtube has made just that. Their videos are amazing, mostly going over the theory created by having an infinite chessboard (“mate in omega” and it’s sequel are mind boggling), and some are about the technical aspects of implementing infinite chess. Highly recommend watching them.

In recent times the developer has been showing some serious miscommunication and other issues regarding their apps. Just look at their terrible handling of the vulnerabilities found in their file manager’s pdf reader (See his responses to the report)

Since around that time, I’ve been looking for alternatives to their apps, but I’ve kept using some of them because I couldn’t find anything that feels as good to use. I guess now I’m forced to really look for those alternatives, or see if there’s any serious fork that still gets actively maintained weeks from now.
