Fianchetto is your personal chess coach in your pocket. It combines playing against an engine, professional analysis of your own games, and personalized training built from your real mistakes - all fully offline, with no subscription and nothing ever sent to the cloud. TWO ENGINES, TWO PERSONALITIES • Caissa (modern NNUE) - shows the objectively best move. • Arasan - a classic engine with a more "human" playing style. Both are compiled natively and run 100% on your device. PLAY • Spar with the bot across five difficulty levels, from beginner to expert. • Choose your color, follow a live evaluation bar, and get engine hints. • Save any game to your Library and analyze it with a single tap. ANALYZE YOUR GAMES • Import games from Lichess and Chess.com (by username, from a link, or from a PGN file). • Every move classified: brilliant, best, inaccuracy, mistake, blunder, missed win. • Accuracy, ACPL, evaluation graph, and key moments of the game. • Quick and deep modes - catch the obvious errors first, then dig into the critical positions. ANALYSIS THAT TELLS A STORY • Every game gets a written recap split into chapters - not just numbers. • Arrows and highlights on the board, with detection of tactical motifs and opening plans. • Two narration tones: casual and technical. Available in English and Polish. TRAIN ON YOUR OWN MISTAKES • Daily puzzles generated automatically from your blunders - not from a generic database. • Smart spaced-repetition system (SM-2) and a daily streak to keep you motivated. • Train the openings you actually play: win rate, accuracy, and recurring mistakes. • Tactical stats, eval-loss heatmaps, and a ranking of your recurring weaknesses. • "Your game" dashboard: Game Score, a skill profile, and a weekly focus to improve. FREE POSITION ANALYSIS • Interactive board with a variation tree and MultiPV analysis. • Position editor, "threat goggles", arrows, and FEN/PGN paste. • Auto-saved sessions - jump back to the position you were analyzing yesterday. SCOUT YOUR OPPONENTS • Import a rival's games and prepare for the matchup. • Opening explorer, repertoire by color, and the opponent's recurring tactical weaknesses. PRIVACY FIRST • All analysis runs on your device - your positions never go to the cloud. • Your data (games, analyses, puzzles) is stored locally. You can wipe it anytime. Fianchetto is built for the club and amateur player who wants to improve systematically - with no subscription and no compromise on privacy. Install it, import your games, and start playing smarter.

Chess, but a little stranger. Oddfish starts with serious Stockfish chess, then changes one rule at a time. RattleFish loses confidence when you play well. GluttonFish grows stronger when you feed it pieces. Restfish makes moved pieces take a nap. Twenty-nine modes across six families turn a familiar board into something wonderfully peculiar. MEET GIL A small gold fish with opinions explains every mode, reacts to the game, and reviews the aftermath. PLAY YOUR WAY • Classic chess or 28 strange variations • Adjustable engine strength • Game history and PGN import • Optional move evaluation and hints • Carefully designed for iPhone and iPad Six modes—including Classic, RattleFish, FumbleFish, Restfish, GluttonFish, and ChapelFish—are free. A single Full Oddfish purchase unlocks every remaining mode. No subscription. PRIVATE BY DESIGN Everything runs on your device. Oddfish has no accounts, ads, analytics, or tracking and does not collect personal data. Stockfish plays the chess. Oddfish supplies the personality problem.
