Train Tactics Seriously



Trainer Fish includes a massive offline tactics database, organized by rating band and tactical theme, with training material for everyone from beginners to grandmasters. Build custom training cycles, solve puzzles, review your mistakes, and steadily climb through more difficult positions.



You can train by difficulty, theme, or mixed puzzle sets. Puzzle ratings help you measure your progress and challenge yourself with harder positions as you improve.



Woodpecker-Style Training Cycles



Create a tactics cycle, solve through it, and continue where you left off. Trainer Fish is designed for repeated pattern recognition training, helping you turn tactical ideas into instinct.



Endgame Training



Trainer Fish also includes endgame practice modes for essential positions, endgame tactics, and endgame studies. Learn technique, calculate accurately, and practice converting positions against Trainer Fish.



Beat the Fish



Play against Trainer Fish, record games, flip the board, save games, and review positions. The Beat the Fish screen is built for both practice games and over-the-board recording.



Game Recorder



Record your own games move by move, with move times shown beside each move. Save your games and use them for later study and analysis.



Visual Studio



Customize your board, pieces, and training pane colors. Choose from multiple board themes and interface palettes so the app feels comfortable during both daytime and night training.



Puzzle Sharing



After solving a tactic, share a clean puzzle challenge image showing the position and your solve time. Challenge your friends to solve the same type of position.



Training Reminders



Trainer Fish can remind you during the day with a puzzle image, helping you build a steady daily chess habit without needing long study sessions.



No Subscription Required



Trainer Fish is designed as a serious chess training app with a simple optional Pro unlock. Train deeply, improve consistently, and build stronger chess habits one position at a time.



Trainer Fish: train, solve, review, and climb.
