Chessful: Train & Analyze

About this app

Understand why you lose. Train what you actually miss. A private chess coach on your device — powered by Stockfish, built around your own games. No ads. No accounts. Fully offline. — WHY CHESSFUL — Most chess apps help you play more. Chessful helps you play better. Instead of confusing engine numbers, Chessful explains every mistake in plain language and turns it into focused, daily training. — UNDERSTAND YOUR MISTAKES — After every game, Chessful shows you: • Where you went wrong • What you missed • Why it mattered Nine mistake categories — from hanging pieces to back-rank weaknesses — explained without jargon. — TRAINING BUILT FROM YOUR GAMES — Your daily plan adapts to your weaknesses, not a generic curriculum. Hang pieces? You'll see more puzzles on hanging pieces. Lose endgames? Endgames take priority tomorrow. Spaced-repetition review locks in what you've learned. — TRACK FIVE SKILLS, NOT JUST RATING — Watch your real progress across: • Tactics • Defense • Positional play • Endgames • Openings — KNOW YOUR OPENINGS — Chessful builds your opening repertoire from your own games — the lines you really play, your win rate in each, and the exact move where you most often go wrong, alongside the engine's better move. Play the London 60% of the time? See precisely where it slips on move 6, then drill it. — PLAY 40 OPPONENTS WITH PERSONALITY — Eight tiers, from Novice to Master. Aggressive, defensive, positional, tactical, endgame specialists — each with a distinct style. Win twice to advance. Optional Game Center leaderboards and achievements. — STOCKFISH, ON YOUR DEVICE — The world's strongest open-source engine, embedded with neural-network evaluation. No cloud calls. No latency.

Monthly, yearly, or one-time lifetime — your choice. — WHO IT'S FOR — You'll feel at home in Chessful if you: • Want to improve but feel stuck • Find engine numbers more confusing than helpful • Prefer structure over endless scrolling • Want a chess tool that respects your attention Free to download.

Play your way. Legal move hints can now be turned on or off in Settings — keep them while you're learning, or switch them off to train your own calculation. The hints are sharper, too: a capture now shows a ring around the piece you can take instead of covering it, and every square shows a single, clean marker. Understand your mistakes. Improve every game.
