KarpaChess teaches chess on the board. Every lesson shows you an idea, lets you play it, then asks you to prove it on a position you have never seen. Train on rated puzzles, play Stockfish 19 and study the masters, in twelve languages. Everything runs on your device: no account, no ads, no tracking. SEE IT, PLAY IT, OWN IT Each of the 100 lessons follows three beats. See the idea on the board, with arrows and moves played out for you. Play it yourself: if you are stuck, the hint is a sentence the lesson's author wrote for that exact position. Then own it, by solving a puzzle on a new position. The patterns you own go into your Pattern Book, and Sharpen brings them back before you forget them. EIGHT ARTS Foundations, The Story of Chess, The Blade (tactics), The First Moves (openings), The Finish (endgames), The Plan (strategy), The Hunt (attack) and The Chess World. They run from setting up the board to the Greek gift and the Lucena bridge. A RATED PUZZLE TRAINER 240 puzzles in twenty packs, rated from 600 to 2000, with solutions several moves deep. Your first try moves your puzzle rating. After that, replay any puzzle to beat your best. PLAY STOCKFISH 19 Four strengths, from beginner to full strength. Play with a real clock, increment included, or untimed. Ask for a hint, take a move back, and come back to an unfinished game where you left it. REVIEW EVERY MOVE When a game ends, every move is graded best, good, inaccuracy, mistake or blunder, and the turning point is explained. THE STUDIO A library of 240 short, decisive master games in 24 collections, from Paul Morphy in the 1850s to the present day. Import your own games as PGN, with their comments and variations kept. Brilliant moves are flagged, and the drawing tools put arrows, lines, highlights, shapes, a pen and text on the board. A HINT WHEN YOU ASK One hint button, answered on your device. It looks at material, king safety, pawn structure, development and loose pieces, and says what matters. MAKE IT YOURS Ten themes, five boards, ten original piece sets, three typefaces and three sound packs. TWELVE LANGUAGES English, French, Spanish, Arabic, Chinese, Russian, Indonesian, Japanese, Hindi, Turkish, Italian and Portuguese. The app, every lesson and every puzzle are translated by hand.
