Chess9 vs Simple Chess Trainer

Hello guys, My name is Shashwat and I made this app chess9 to play and enjoy the game for fun it has luxury board where pieces are made up of black and gold color. Please feel free to check features like Check, Checkmate, Castling, Pawn capturing to opposite board and progressing to Queen. Guys, when you play the game the opponent is meant to be very easy so everybody can learn, progress, try different moves and grow and be the best at their own pace. So definately give it a shot and keep growing and learning. Thank you!

Simple Chess Trainer is a focused practice tool for chess players who want faster board recognition, sharper annotation skills (for beginners), and tighter opening repertoire memory (for all levels) — all free, with no subscriptions or accounts. Square Recognition. Drill all 64 squares with timed sessions, custom filters (whole board, light/dark only, ranks 1–4, etc.), and a focus list that biases toward squares you've missed in the last 90 days. Toggle coordinates off when you're ready to find squares from memory. Annotation Drill for Beginners. Step through any PGN game move-by-move, identify mistakes, and let the engine queue tough positions for review. The Review Queue surfaces moves you've gotten wrong three times running until you've beaten them three times in a row. Opening Repertoire & Move Trainer (All levels). Drag the right move (or type it) for both sides of any game or opening line in your library. The new Random Review mode picks games weighted by how much you've struggled — your hardest lines surface first; mastered ones come up rarely so you don't drill what you already know. Library. Import any standard PGN file to build your own repertoire or review your own games. The app indexes thousands of games in seconds and ships with 20 verified historical classics on first launch — Morphy's Opera Game, Anderssen's Immortal, the Game of the Century, Kasparov's Immortal, and more. Stats. 7-day / 30-day / 90-day / all-time views of accuracy, response time, square-error heatmap, piece-error breakdown, and per-game Move Trainer mastery. Export everything as JSON anytime. Works fully offline. Private by default. Every drill, import, and statistic stays on your device. No accounts, no servers, no chess-data analytics, no subscriptions — ever.
