by chess lovers, for chess lovers
Failure is not the opposite of success, it is part of it.
WHAT IS IT?
Blunderzone turns your own games into practical chess training.
- Import games from lichess.org or chess.com
- Analyze them in stages: quick, normal, and deep analysis for premium users
- Turn missed ideas into puzzles for game-based, quick, and memory training
New games are checked regularly, so training stays close to what you have just played.

I always make the same damn mistakes.
Why train from your own games?
- The positions match your openings, time controls, and practical habits
- You review your worst moments instead of solving unrelated puzzles
- The app keeps separate flows for daily game-based practice, fast sessions, and spaced repetition
