Improve at chess with ChessFlow, an app designed to help you train your openings, build your repertoire, solve tactical puzzles, and track your progress.

ChessFlow offers an interactive chessboard, training modes, statistics, and customization tools to make your sessions more regular and better structured.

♟️ Build your opening repertoire

Create your own repertoires for White and Black directly from the chessboard. Add your variations, comments, and important positions, then organize your openings into folders.

You can import or add content from several compatible sources:

• PGN file or text
• Lichess game
• Lichess study
• Chess.com game

ChessFlow also lets you merge multiple repertoires, save your favorite variations, and export your lines in PGN format.

🧠 Memorize your openings

Train yourself to find your lines directly on the board instead of only rereading them.

Several training modes are available:

• full repertoire
• progressive learning
• random positions
• review of weak moves
• main line training
• opponent-side training

The moves you miss most often can be identified to help you focus your reviews on the positions that need the most work.

📊 Track your progress

View your training statistics to follow your activity and improvement:

• mastery of each repertoire
• average score
• number of sessions and positions played
• total training time
• mistakes and hints used
• progress over time
• activity rhythm and best streak

These data help you see which lines are well memorized and which ones need more review.

🧩 Improve your tactics

Solve chess puzzles to work on your calculation and recognition of tactical patterns.

ChessFlow offers several formats:

• daily puzzle
• survival mode with progressive difficulty
• random puzzles
• training by tactical theme
• puzzles linked to an opening
• mistake notebook to replay failed exercises

Puzzles may cover different themes such as forks, pins, skewers, sacrifices, endgames, discovered attacks, and other common tactical patterns.

🔍 Analyze and explore your positions

Use Stockfish to view a position evaluation and see a suggested best move.

Freely explore new variations from a position, then choose the ones you want to add to your repertoire.
