Riichi Mahjong Coach is not a real-time game assistance app.

It does not read the game screen, automate the game, or provide real-time recommendations. It is a learning tool used for reviewing and practice by allowing users to input their own hand. Beginners can easily identify “why there are no Yaku,” “how many Shanten there are,” and “what to discard to improve,” while intermediate players can practice judgment by comparing valid tiles and Yaku possibilities for each discarded tile.

This is not an accurate win rate calculator, but a learning analysis tool based on the currently entered hand. Opponent's discards, score situations, and the flow of the actual game may not be reflected in some analyses.
