Déjà Move is a chess trainer that turns your own games into chess puzzles. The app analyzes your Lichess & Chess.com games with the Stockfish chess engine to find your mistakes, blunders, and missed tactics. Every position where you went wrong becomes a puzzle: you play it out against the engine until you reliably find the better move. Learn from your mistakes instead of repeating them, and improve your rating where it counts.

HOW IT WORKS
• Mistakes from your games: mistakes in the opening, middlegame and endgame plus missed tactics, selectable by category and difficulty.
• Spaced repetition: each task comes back in six phases, after 1, 3, 7, 14, 30 and 60 days. Solve it and it moves up a phase, miss it and it goes back to phase 1.
• Puzzles from your own games: mistakes in the opening, middlegame, and endgame, plus missed tactics, selectable by category and difficulty.
• Spaced repetition like flashcards: each puzzle comes back in six phases, after 1, 3, 7, 14, 30, and 60 days. Solve it and it moves up a phase; miss it and it goes back to phase 1. That is how patterns stick for good.
• Real resistance: you don’t just play one move, you play the position out, whether that means checkmating, converting an advantage or holding the draw. Stockfish runs right on your device.
