Learn from every game you play Connect Chess.com or Lichess, and Chessdock turns your own games into focused reviews and personalized puzzles. Most chess apps train you on random positions from master games. Chessdock is different. It analyzes the games you actually play, finds the mistakes that mattered, and hands them back to you two ways: as a game review you can work through move by move, and as puzzles built from your own slips. Instead of practicing positions that may never come up, you fix the exact moments where your thinking broke down. GAME REVIEWS — see your game through its mistakes • Only the moves that counted — your mistakes, and your opponent's, not the whole game • A winning-chances graph that shows exactly where the game slipped away, or came back • Work each mistake your way: solve it blind like a puzzle, take a hint, or just reveal the best move • Go deeper anytime — open the engine on any position, try your own ideas, and see how the game really played out PUZZLES — your mistakes, as personalized puzzles • Nothing random. Every puzzle comes straight from a game you played • A full library ready now that grows every time you play • Smart selection finds the mistakes actually worth solving • Jump from any puzzle into the full game in one click ALSO INCLUDES • Fresh-game alerts — get notified minutes after you finish a game online • Analysis board — open the engine on any position you like • Bookmarks — save the games and puzzles worth revisiting • iOS & Android apps — your games and puzzles, on the go HOW IT WORKS 1. Connect your Chess.com or Lichess account 2. Chessdock analyzes your games and finds the mistakes that mattered 3. Review each game, then train on puzzles made from your own play 4.

Chessdock's advantage is rating (5.0 vs 4.8) and update cadence (every 2 weeks vs monthly). On price, ads and device support there is nothing between them.
