About

My Blunders

Features
Read full description

Most chess apps give you someone else's puzzles. My Blunders builds them from your own games, so you practise the positions where you actually went wrong. Enter your Lichess or Chess.com username. The app downloads your recent games, checks every move with Stockfish right on your device, and turns your mistakes into puzzles. The first ones appear while the rest of your games are still being checked, and new ones keep arriving in the background as you solve. You don't need an account or a password. If you'd like to start before importing anything, there's a built-in library of famous blunders from chess history. FOUR WAYS TO TRAIN - Puzzles: Find the move you missed in your own games. If you're stuck, Hint shows which piece to move without giving the answer away. Once it's solved, replay your game move or the engine's best line on a separate board, or play the position out against the engine. - Opening: Your games mapped into an opening tree. See where you leave the book, spot your weak lines and drill the worst of them. You can also save your repertoire as an A1 poster, a tree of boards with the engine evaluation and your wins, draws and losses under each one. - Coordinates: Learn the board by heart. Name squares against the clock, tell light squares from dark ones at a glance, and step through famous games move by move. - Play: A full game against an engine set to your rating. Each move is judged as you play, and the best move appears on a mini board where you can try it. Turn on the clock and the engine paces itself like a person, quick in the opening and slower when the position gets sharp. Choose a board in Green, Wood or Walnut, with a separate one for light and dark mode. PRIVACY - No account, no ads, no tracking. - The app reads only your public games. They go straight from Lichess or Chess.com to your device. There is no My Blunders server. - All analysis runs on the device and works offline once your games are downloaded. My Blunders is free, with no in-app purchases or subscriptions.
