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.
