Chess Diagnostics: Chess Coach

Do you want to improve your chess, learn chess tactics more effectively, and are you looking for a professional chess analysis app? Do you keep losing in the endgame? Are you losing chess games due to the exact same mistakes?

Chess Diagnostics is your personal chess trainer and chess coach right on your smartphone. The app analyzes your real chess games and pinpoints exactly where you are losing points – so you can practice with targeted training instead of solving random, generic chess puzzles (puzzles).

── YOUR GAMES. YOUR WEAKNESSES. ──

Connect your Lichess or Chess.com account in just a few seconds. The app automatically imports your recent games and analyzes them using the Stockfish chess engine – completely free via the Lichess Cloud, without needing your own server.

── PRECISE CHESS ANALYSIS & WEAKNESS TRACKING ──

Chess Diagnostics is much more than just a simple chess board: It detects recurring patterns across dozens of your games:

• Chess Phases: Where do you make the most mistakes – in the chess opening, the middlegame, or the chess endgame?
• Time Pressure: Does your accuracy drop when the clock is ticking?
• Chess Tactics: Which tactical motifs (forks, pins, skewers) do you regularly overlook?
• Progress: How is your accuracy and Elo trending over the past few weeks?

Blunders, mistakes, and inaccuracies are categorized by game phase and displayed in clean, visual charts.

── TARGETED CHESS TRAINING & LEARNING ──

Based on your actual weaknesses, the app recommends customized Lichess studies. No generic chess training – only what your chess game actually needs to grow. Work through interactive chapters directly inside the app, with integrated progress tracking.

── GAME REPLAY & BLUNDER COACHING ──

Replay every game move by move. Mistaken moves are highlighted on the chess board, showing you exactly where the game turned and what the best engine move would have been according to Stockfish.

── NO SUBSCRIPTION. ONE-TIME PURCHASE. ──

$2.99 / €2.99 one-time payment – no subscription traps, no hidden fees, no paywalls. Buy once, use forever. Perfect for club players and chess hobbyists looking to improve chess skills – without an expensive chess coach.
