About

ChessFlow

Features
Read full description

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. 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, at a strength you choose. Explore variations in free analysis and export them. YOUR REPERTOIRE, FROM ANY SOURCE Import from PGN files, paste FEN positions, or link an iCloud folder from another chess app - ChessFlow reads your files and never changes them. Attach a course PDF or your notes to any repertoire; PDFs even reopen at the page you left, on every device. BUILT TO KEEP YOUR DATA SAFE Everything syncs across your iPhone and iPad via iCloud - lines, progress and colors. Training progress is merged across devices, never overwritten. Automatic daily backups, plus manual export and import. EXPORT & SHARE Copy or share your lines as PGN for lichess and chess.com. Export your games versus the computer as PGN or a tournament-style PDF scoresheet. Free to try, with a 14-day full-access trial. Subscriptions unlock unlimited training on the virtual board, or everything including the physical board. Requires iOS 17 or later. iPhone and iPad, one app. Questions or feedback? developer@chesstools.it Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.chesstools.it/chessflow/privacy.html
