Chess Grandmaster AI

New in V1.2: Review completed games move by move, study results by side, replay the same setup, and challenge stronger offline AI—one-time Premium, no subscription.

Play chess offline, watch chess engines compete, and review completed games—all without creating an account.

Chess Grandmaster AI is an offline chess practice and study app for iPhone and iPad. Choose a side and play against the built-in chess engine, or use Watch and Learn to observe both sides playing automatically.

PLAY AND WATCH OFFLINE

• Play locally against the computer • Choose White or Black • Watch engine-versus-engine games • Select from six AI strength levels • Adjust search depth and game options • Review move history and captured pieces • Use undo, restart, resign, and board-flip controls • Play with clocks, increments, and AI move pauses • Practice without an account or server connection

LEARN WITH GAME REVIEW

Premium Game Review helps you study a completed local game:

• Inspect moves on an interactive review board • Navigate with First, Previous, Next, and Last • See move-quality and analysis-confidence labels • Review important alternatives and bounded lines • Compare result categories for White and Black • View a complete post-game summary • Share or print the review summary • Export optional diagnostics for a specific game • Replay another game with the same setup

Review analysis runs locally on your device. Completed reviews are cached locally for faster reopening. Because the analysis uses bounded local search, positions that cannot be evaluated confidently are clearly marked Insufficient depth.

SIX AI STRENGTHS

Free:

• Beginner • Club

Premium:

• Tournament • Master • Grandmaster • Maximum

The stronger levels search deeper tactical lines and include improved capture safety, trade handling, repetition avoidance, promotion choices, and king-and-major-piece endgame conversion.

MAKE THE BOARD YOURS

Customize board themes, chess-piece styles, player avatars, music, move sounds, alerts, timers, display zoom, and other local settings.

ONE-TIME PREMIUM UNLOCK
