ChessMistakeDriller: Openings

Tired of making the same blunders in your Lichess games? Fix your chess openings by drilling the exact mistakes from your own Lichess games.

This app offers two powerful training modes:

Your Games (Lichess Account Required): Get personalized puzzles based on the mistakes from your own game history.

Grandmaster Games (No Account Needed): Analyze games from world-class players like Magnus Carlsen and Hikaru Nakamura to learn from their decisions.

ChessMistakeDriller connects directly to an Lichess.org account and transforms your game history into a powerful, personalized training tool. Instead of random tactical puzzles, you'll drill the exact mistakes you made in your own games, turning your weaknesses into strengths.

How It Works:

Enter Your Lichess Username: Simply provide your public Lichess.org username. No password required.

Instant Analysis: The app fetches your recent games and uses the power of the Stockfish engine to find your first significant mistake in each one.

Solve the Puzzle: You are presented with the exact position right before your error and challenged to find the better move you missed. It's the most effective way to learn from experience.

Key Features:

🎯 Truly Personalized Puzzles: Stop training on generic positions. Every puzzle is generated from a mistake you actually made in a real game on Lichess.

📚 Opening-Specific Drills: The app automatically groups your mistakes by the opening you played (e.g., Sicilian Defense, Queen's Gambit). Discover which openings are causing you the most trouble and drill them specifically.

🔍 Built-in Analysis Mode: Made the right move? See how Stockfish would have continued. Want to explore a different line? Enter the full analysis mode with an evaluation bar to dive deeper.

🔒 Privacy-Focused: No ads, no trackers, and no user accounts. Your Lichess username and drill statistics are stored only on your device.

Free vs. Pro Version:

This app is free to use and fully featured. The only limitation is the number of games analyzed per run.

Free Version: Analyze up to 10 of your most recent games. Perfect for getting a feel for your current blunders.

Pro Version (In-app Purchase): Unlock analysis for up to 1,000 games, giving you a comprehensive overview of your habits across hundreds of games. Choose between a yearly subscription or a one-time lifetime purchase.

Stop guessing how to improve. Start learning from your actual gameplay.
