ChessGrind vs My Blunders

ChessGrind is a tracker for chess players who want to improve. Log your games, see your real numbers, build your opening repertoire, and keep a list of the mistakes that cost you, with a fix for each. No account, no tracking. Everything lives on your device and in your private iCloud, and syncs across your iPhone, iPad, and Mac. A GAME JOURNAL THAT ADDS UP Log every game with the result, the side you played, the time control, the opponent, and the opening. Filter by result and watch the journal grow into your record. YOUR REAL NUMBERS ChessGrind computes your win rate and your record split by color and by time control, so you learn that you score well with White in rapid but leak points in blitz as Black. The numbers come only from the games you log. A RATING CHART YOU CONTROL Note your rating whenever you check it and ChessGrind plots the trend. Keep separate lines for Chess.com blitz, Lichess rapid, or your over the board rating, and see the change over the last thirty days at a glance. A STUDY ROUTINE AND A STREAK Log study blocks by theme: tactics, endgames, openings, strategy, and game review. A streak counts the days you keep it up, a two week strip shows your rhythm, and a chart breaks down where your time actually goes. Turn on a daily reminder to protect the streak. THE LEAK LIST YOU ACTUALLY FIX Name the mistakes that keep costing you games. Give each one a category, the pattern behind it, and the fix you will use instead, then advance it from open to working to fixed with a tap. This is the feature that turns review into progress. OPENING REPERTOIRE Save the openings you play with the main line, the ECO code, and the plans and ideas behind them. Pull one into a game entry with a tap.

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. The same games also build your opening repertoire, and you can take it off the screen. Print it as an A1 poster, or save it as a wallpaper for your desktop at 3840 × 2160. Each board carries the move, the engine evaluation, and your wins, draws and losses from that position. 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.
