Learn chess step by step, right on your phone. ChessCoach is a chess course that opens on Today's Learning. Every day it lays out a short plan (a daily puzzle, one lesson, a tactics set and a practice game) and tracks your progress by chapter and by theme. ■ 20-lesson curriculum Five chapters: Basics, Opening principles, Tactical motifs, Intermediate, Endgame basics. New lessons end with exercises on the board, checked move by move by the rules engine, with an explanation after every answer. · Control the centre, develop your pieces, castle · Count attackers and defenders, knight forks, queen double attacks · Mate with queen and rook, promotion and the rule of the square, the opposition ■ Game review that explains After a game against the on-device AI, the app picks your biggest mistakes and says why in plain words: a piece left undefended, a missed checkmate, a missed fork. It links to the lesson that teaches the idea, and each mistake becomes a puzzle you can retry. ■ 1,200 puzzles 1,000 checkmate puzzles (mate in one, back-rank mates) and 200 tactics puzzles (forks, pins, skewers, discovered attacks). Every tactics puzzle was checked by the on-device engine to have one clear best move. A daily puzzle and streak. Accuracy per theme shows your weak spots and suggests a lesson to review. ■ Practice games An AI from Elo 400 to 2400, unlimited free hints, move-by-move replay and PGN export. ■ Opening library 15 openings replayed move by move, with the idea behind each. ■ No account, all on your device No server, no login. Lessons, puzzles and the AI all run on your device, even in airplane mode. Your progress never leaves your phone. ■ 5 languages English, Korean, Japanese, Chinese (Simplified and Traditional). ■ Free and the Full Course Free: the first 5 lessons (Basics chapter), Today's Learning, 1,000 mate puzzles, the daily puzzle, the first 5 puzzles of each tactics theme, AI games with hints and review, the opening library and My Progress.
