Store description excerpt
LINA CHESS - Offline Chess Analysis & Training Understand your moves, practise with purpose, and bring what you learn to the board. LINA CHESS combines on-device Stockfish analysis, AI play, tactical puzzles, opening lessons, and game review in one app for iPhone and iPad. Available in English, Korean, German, Russian, French, Spanish, Japanese, Chinese, and Portuguese, with clearer learning messages. ANALYSE EVERY POSITION • Use the Stockfish engine for real-time position analysis without an internet connection. • Read centipawn evaluations and mate distances with the evaluation bar and move-by-move advantage graph. • Follow arrows for recommended moves and possible opponent threats. • Compare up to three engine lines. On compact screens, expand extra lines when you need them and collapse them to keep the board in focus. • Adjust analysis depth and choose which analysis aids appear. PLAY YOUR WAY • Challenge the AI at a difficulty that suits you, or play a local two-player game on the same device. • Switch between AI and local play during a game. • Return to a position in your game review and play it out against the AI to test another idea. LEARN OPENINGS, NOT JUST MOVE ORDERS • Explore 20 guided openings with background, move-by-move explanations, alternatives, and plans for the position at the end of each line. • Search openings and filter by colour or favourites to build a collection you want to study. • Study the reasoning, then test your recall in move-by-move quizzes. • Explore supported alternative continuations and jump to a related opening when a matching lesson is available. • Use FSRS-based spaced repetition to revisit opening material over time. • Review difficult positions separately, choose what to retry, and see dated records of your attempts. • Distinguish moves answered without help from hints and wrong attempts. • Continue from the final lesson position against the AI, turning opening knowledge into practical experience. BUILD TACTICAL CONFIDENCE • Train with more than 50,000 puzzles, covering ratings from 800 to 3000+. • Filter by rating, theme, and solving status, including unplayed, solved, and failed puzzles. • Practise forks, pins, skewers, back-rank mates, discovered attacks, and other recurring patterns. • Ask for a one-move hint when you are stuck. An arrow reveals the next move without giving away the whole continuation. • Hint-assisted attempts are recorded separately from unassisted successes. • Browse puzzle history, follow rating changes, and return to difficult puzzles for focused practice. • Pause a puzzle and continue later. TURN GAMES INTO LESSONS • Save games automatically as local PGN records and replay them move by move. • Review accuracy and mistake counts for both sides, with move-quality feedback from Brilliant, Great, Best, Excellent, and Good to Inaccuracy, Mistake, Miss, and Blunder. • Identify openings and variations automaticall
