— 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. No data leaves your phone.
— PRIVATE BY DESIGN —
• No accounts
• No tracking
• No ads
• Your games stay on your device
— DESIGNED FOR FOCUS —
Calm dark interface. No streak guilt. No notifications begging you back.
Native on iPhone, iPad and Mac — with a 3D board on the larger screens.
— PREMIUM —
Unlock unlimited analysis, the full daily training engine, deeper coach hints, your complete opening repertoire, all 40 opponents, and your full skill profile.
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. Start with one game. See what you've been missing.

1.8.3 1d ago
You said that being shown the right move isn't the same as playing it. So now you play it.
NEW — PLAY THE MOVE YOU MISSED
— Miss it, then fix it. Get a training move wrong and Chessful puts the position back and hands you the board. The session waits until you have played the right move yourself.
— "Try Again" on the ones you missed. Finish a session under 70% and the recap offers a re-drill of exactly the exercises you got wrong — and it doesn't cost a daily puzzle.
— More than one right answer. Puzzles now accept any move the engine rates as equally good, so an alternate mate is no longer marked wrong. Puzzles you already have get updated in the background.
— Puzzles built from your games carry their real pattern name instead of all reading "Missed Tactic".
PROGRESS YOU CAN TRUST
— Skill scores no longer drift down just because you keep playing. They measure how cleanly you play, weighted by how much Chessful has actually seen.
— Training now moves your skill bars. Insights refresh when you open the app instead of waiting for your next game analysis.
— Endgame and opening scores follow how often you really reach those phases, and a category with too little evidence reads "Not measured yet" instead of a number we can't stand behind.
IMPORTED GAMES
— Edit or delete an imported game, including correcting which side you played.
— After an import you land on a game that has actually been analyzed.
— The import summary accounts for every game, including any whose analysis failed.
— Closing the import sheet now stops the batch instead of leaving it running.
Almost all of this came straight out of your emails. Keep them coming.
