ChessFlow is the training app built for tournament players - openings, middlegames and endgames - and the only one that lets you drill them on a real electronic chessboard. Train your lines on screen, or connect your Chessnut board over Bluetooth and practice with real pieces in hand, guided by the board's LEDs. Then let spaced repetition bring each line back right before you'd forget it, so your prep actually sticks. TRAIN ON A REAL ELECTRONIC BOARD Connect your Chessnut (Go, Air, Air+, Pro) and train with the pieces in your hands. The LEDs guide you - steady light for your opponent's move, a blink for a hint, a fast blink when the app plays the move for you. Make a mistake? Retry, ask for a hint, or let the app show you. REMEMBER YOUR OPENINGS WITH SPACED REPETITION ChessFlow uses an SM-2 algorithm adapted for chess openings: every line returns right before you're likely to forget it. Only a perfect run speeds up the schedule; anything shaky comes back tomorrow. No line ever disappears for months. A seven-day forecast shows how many lines come due each day, so you always know when a backlog clears. DRILL YOUR WEAK SPOTS ChessFlow tracks the positions where you go wrong most often and serves them back as targeted puzzles. Turn on Drill random positions for an endless stream of positions from the lines you've trained in the open repertoire - a fast way to keep it sharp. PRACTICE ANYWHERE ON THE VIRTUAL BOARD No hardware needed. Train on screen with tap-to-move and premove, just like chess.com and lichess. Your iPad becomes a training station; your iPhone keeps your repertoire in your pocket. PLAY IT OUT AGAINST STOCKFISH Stop anywhere in a line and play the position out against Stockfish 19, at a strength you choose. Explore variations in free analysis, with a slim evaluation bar beside the board, and export them.
