Chess Training Center

Chess Training Center is a complete chess training app built around the free, open-source Stockfish engine, no ads, no gimmicks, just serious training tools.

ANALYZE
Import PGN games or play them out live, and get instant engine evaluation with up to 2 lines of analysis, move-quality grading (brilliant, good, inaccuracy, mistake, blunder), and full annotation tools, arrows, colored squares, comments, and NAG symbols.

TRAIN TACTICS
Thousands of puzzles rated by difficulty, with an ELO system that adapts to you. Try Puzzle Rush for a timed challenge, or Blindfold mode if you're feeling brave.

STUDY OPENINGS
Practice your own opening repertoire against an engine that plays real theory from your imported games, at 8 difficulty levels, and improvises soundly once you're out of book.

MASTER ENDGAMES
Curated endgame positions organized by material (pawns, rooks, queens, bishops, knights) to build real technique, not just memorized lines.

LEARN THE FUNDAMENTALS
Step-by-step interactive lessons on the rules of chess and basic checkmate patterns, for players just getting started.

TRACK YOUR PROGRESS
Separate ELO ratings for tactics, openings, endgames, and blindfold play, daily streaks, achievements, and an optional public leaderboard.

Chess Training Center works fully offline once loaded, your games and progress are stored on your device, with optional cloud sync if you create a free account.

No subscriptions, no in-app purchases, no ads. Just chess.
