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 ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | ChessFlow Premium | $8.99 | per month | | ChessFlow Premium | $49.99 | per year | | ChessFlow Virtual | $4.99 | per month | | ChessFlow Virtual | $29.99 | per year | ## Version history (last 5 releases) ### 1.0.7 — 2026-09-07 More room on small screens. On iPhone SE, opening a line left the training buttons below the edge of a page that does not scroll, so there was no way to start. The move list is shorter there now, the board keeps its full size, and White, Black and Play vs Computer are all within reach. The guide is clearer about hints: on a Chessnut board the destination square lights up, and on the board on screen it is highlighted. ### 1.0.6 — 2026-09-05 Small screens are welcome again. On iPhone SE and other short screens the home screen now fits, so loading a PGN or importing a folder is right there instead of below the edge. Import from folder: you can search for a repertoire and still see the button that adds it. Search, tick, add. Your library also marks a file with its source and its attachments the moment you set them, without waiting. ### 1.0.5 — 2026-09-03 Your repertoire stays put. Edit a PGN outside ChessFlow - add a line in another app, or take one out - and the file keeps the colour you play it as, and stays in the section where you filed it. When a critical position will not come to you, you can now ask to be shown the move. Play it yourself and carry on, instead of leaving the session to get past it. The library also shows at a glance which files carry a source, so you can see what you have filled in without opening them one by one. ### 1.0.4 — 2026-08-30 ChessFlow now explains itself. A new guide, "How ChessFlow works", covers how a PGN becomes lines, why a line comes back for review, and what the drill actually practises. You will find it behind the (i) on the home screen, or as the first row of Settings. A repertoire file can also record where it came from - the course, book or coach, with a link when there is one - and hold two attachments instead of one. ### 1.0.3 — 2026-08-26 Resetting the progress of an opening now really clears it, on every device you use. Scores, training dates and critical positions for those lines start from zero again, and stay that way. ## Apps similar to ChessFlow | App | Rating | Price | Category | | --- | --- | --- | --- | | [Gambits Edge: Chess Scanner](https://appshunter.io/ios/app/gambits-edge-chess-scanner/id6769525049) | 5.0 (2) | Free | Games | | [Football Tactics 2026](https://appshunter.io/ios/app/football-tactics-2026/id6781993793) | — | Free | Games | | [Chessight](https://appshunter.io/ios/app/chessight/id6762118668) | — | Free | Games | | [Chess Trainer: Opening Drills](https://appshunter.io/ios/app/chess-trainer-opening-drills/id6757406914) | 5.0 (2) | Free | Games | | [ChessBased: Stockfish 19](https://appshunter.io/ios/app/chessbased-stockfish-19/id6773557320) | — | Free | Games | | [Chess Opener PRO](https://appshunter.io/ios/app/chess-opener-pro/id1489282483) | 4.4 (80) | $8.99 | Games | ## More apps by Giorgio Donnoli - [ChessTools.it](https://appshunter.io/ios/app/chesstoolsit/id6791041579) All apps by Giorgio Donnoli: https://appshunter.io/developer/6777981338 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
