— 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
— 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, 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

• Prefer structure over endless scrolling
• Want a chess tool that respects your attention

Ratings & Reviews

Bring your real games in. Now you can import PGN files from chess.com, Lichess or other source and analyze them with Stockfish — and Chessful Premium is now Family Sharable.
New:
— Import PGN games. Paste a single game or pick a .pgn file with a year of chess.com or Lichess history. Up to 500 games per import, with duplicate detection.
— Stockfish on imports. Every imported game runs the same accuracy + mistakes + weaknesses analysis as the games you play in‑app.
— Skill profile, your call. A per‑import toggle decides whether a batch counts toward your weakness bars — keep recent play, archive the rest.
— Apple Family Sharing. One subscription, up to 5 family members, no extra cost. Train together.
Thank you for playing — and now, for importing.
