ChessFlow vs Chessbrix

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. 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.

You reach an endgame a pawn up and the win slips away. Chessbrix is built to fix exactly that. 384 positions across 33 chapters take you from mating with a lone rook to the rook and pawn endings that decide master games. Every chapter opens with guided lessons that walk you through the plan move by move, then gives you positions to practise it on. WHAT YOU GET • 384 endgame positions across 33 progressive chapters • 192 move-by-move lessons that explain the idea before asking for the move • Basic mates, pawn, rook, bishop, knight and queen endings • Spaced repetition brings back the positions you got wrong, until they stick • A daily challenge and a streak to keep you coming back • Hints with on-board arrows when a position will not give • Play any position out against the engine to see why the plan works • An analysis board with undo, redo and PGN export • Notes you can attach to any position • Progress tracked per chapter, so you can see what is still weak START FREE The beginner chapter is completely free: 36 positions on checkmating a lone king, with no time limit and no account. Work through it before deciding whether the rest is for you. BUILT FOR IMPROVEMENT Positions are graded from under 1000 to roughly 2300 Elo and grouped by concept, so you can start where you actually are. Nothing here is filler. Every solution is checked against a chess engine and an endgame tablebase before it ships, so the answer you are shown is the right one. NO ACCOUNT, NO TRACKING Chessbrix works entirely offline. There is no sign-up, no advertising, and nothing about you leaves your phone.
