Are you able to solve chess puzzles but struggle to find those same tactics in your own games? Or are you simply looking to improve your tactical awareness and opening knowledge? Then Chess Pro Trainer is for you. Chess Pro Trainer is unlike any chess training app available today. It is designed to improve your tactical vision, calculation, pattern recognition, opening preparation, and overall chess strength through realistic in-game simulation training. Most puzzle apps teach you HOW to solve tactics. Chess Pro Trainer teaches you HOW and WHEN to look for them. In traditional puzzle apps, you know a tactic exists before you make your first move. In real games, nobody tells you a tactic is there. Chess Pro Trainer recreates that experience by presenting positions from real games where tactical opportunities may appear immediately or several moves later. This creates a realistic training environment that directly improves practical over-the-board and online play. The app also features an advanced Alternate Acceptable Move system. Rather than simply marking moves right or wrong, users can earn credit for finding Valid, Equal, or even Better moves than those played in the original game. This rewards creativity, strong decision-making, and deeper calculation. 7 CORE TRAINING MODULES • Tactics Recognition Training Train both tactical awareness and tactical calculation through a unique two-phase training system. • Genius Training Develop attacking instincts through aggressive sacrifice positions and high-level tactical play. • Checks Training Master the ability to identify every possible check in a position. • Coordinated Squares Training Learn to recognize key action squares that often serve as the foundation of powerful tactics. • Unprotected Pieces Training Develop the ability to identify vulnerable pieces using a deeper definition of what "unprotected" truly means. • Mate Puzzles Training Sharpen your checkmate vision with puzzles from Mate in 1 through Mate in 8. Visualization Mode freezes the board so you must calculate the entire mating sequence in your head, and Multi-Checkmate Mode challenges you to find every mating solution in a position. • Openings Training (NEW!) Learn openings the way a coach teaches them. Lines are built for 4 rating ranges (0-799, 800-1399, 1400-1999, 2000+) based on what players at your level actually play. Study each line with coach comments, arrows, and highlighted squares, then train it from memory while the app plays your opponent's replies. Includes Only Move alerts, hints, random or in-order training, and Train All Subcategories to mix every line of an opening into one session. ADDITIONAL FEATURES • Stockfish-powered Analysis Board • Global Leaderboards • Detailed Statistics Tracking • Multiple Difficulty Levels • Board Themes and Sound Customization • Learning Coordinates Module • Random Position Generator • Regular Content Updates Whether you are a beginner or an advanced player, Chess Pro Trainer provides a focused and efficient way to improve your chess skills through realistic training. This is not just another puzzle app. This is a complete chess training system. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Recognition is in beta. If Chaal is unsure about a square, you confirm the piece before analysis instead of letting the app guess. How it works 1. Import a position from a screenshot, app, or chess book. 2. Confirm the board and choose the side to move. 3. Review the best move, alternatives, evaluation, winning chances, and explanation. Chaal saves every result automatically. Search previous analyses, see opening names when available, and share your analysis with others.
