Chessmate: iOS chess opening trainer that quizzes forgotten moves

Chessmate is an iOS app that helps chess players practice openings by presenting positions one at a time and quizzing them on the correct moves, especially those they tend to forget. It uses LLMs to generate explanations for why a move works, addressing the common problem of forgetting both the move and its rationale after studying.

The app focuses on spaced repetition of chess openings, showing a position and asking the user to recall the next move. If the user forgets, the app brings back the move and provides an explanation of why it works, likely generated by an LLM. Built for iOS, it targets intermediate players who study openings but struggle to retain them in actual games. No tech stack or traction details are provided beyond the Reddit post.
