## What is ChessCoach?

A full game of chess, complete on your phone.

ChessCoach is an on-device chess app that works without servers, logins, or the cloud. Even the AI engine runs on your device, so it plays exactly the same in airplane mode. Your data never leaves your phone.

■ Full rules
· Castling, en passant, promotion with piece choice
· Checkmate, stalemate, 50-move rule, insufficient material, threefold repetition
· 10-minute clock, standard PGN notation

■ AI from Elo 400 to 2400
21 levels from beginner to master. Lower levels wobble like humans; higher levels calculate deeper. Moves come back within 3 seconds.

■ Hints
Stuck? The hint button shows the best move and alternatives with evaluations.

■ Mistake analysis
After each game, every move is graded — see your accuracy, average loss, and blunder count.

■ Review & PGN
Step through games move by move, export or import standard PGN.

■ 1,000 puzzles
Tactics training by theme — forks, pins, skewers, back-rank, mates. A fresh daily puzzle keeps your streak alive.

■ Opening library
Learn 15 openings from the Ruy Lopez to the Sicilian, replayed move by move.

■ 5 languages
English, Korean, Japanese, Chinese (Simplified & Traditional).

No ads, no purchases, no accounts. Completely free.
