ChessView vs Chess411

See a chess position anywhere — in a book, on another screen, on the table in front of you — and have it on a board you can play with, in seconds. ChessView is a study tool, not another place to play. Scan a position with the camera or from a screenshot, open a PGN file, or pull in your Chess.com games — then replay them, branch off, and work out what actually happened. Free, offline, no account, no ads, no tracking. SCAN A POSITION FROM A PHOTO Point the camera at a real board, or choose a screenshot from Chess.com, Lichess or a chess book. ChessView reads the position and puts it on your board. Anything it misreads, you fix in the position editor — then start playing it out. PLAY IT OUT ON A REAL BOARD Full move validation: legal moves, en passant, castling, promotion. Drag the pieces, step back and forth through the whole game, flip the board, and branch off wherever you want to see what would have happened. OPEN PGN AND FEN FROM ANYWHERE PGN files from Files, Mail, Messages or any app that can share them. Paste a FEN string and it loads. Export any position or game as PGN, FEN or a PNG image, and share it in one tap. YOUR CHESS.COM GAMES, OFFLINE Type your username, pick a month, and your games are in the library — ready to replay any time, with or without a connection. STUDY THE CLASSICS Famous games come built in — Byrne–Fischer, Morphy, Short–Timman, Lasker–Thomas — so there is always a position worth looking at. SEE THE EVALUATION Evaluations and main lines come from the Lichess cloud database: free, fast, no account needed. For positions the database doesn't know, ChessView offers a sensible continuation of its own. OPTIONAL: COMMENTARY IN PLAIN WORDS Add your own OpenAI API key and ChessView will explain a position or a whole game in sentences — the plan, the key ideas, the moment it turned. Entirely optional: everything above works without it. Your key is stored in the iOS Keychain, used only from your device, and never sent to us. PRIVACY, ACTUALLY No account. No ads. No analytics. No tracking. Your games and your settings stay on your iPhone and iPad. WHY I BUILT IT Getting a chess position onto my phone used to be absurdly hard. A diagram in a book, a screenshot from a game, a FEN string someone sent me — none of it could just be opened and played through on an iPhone. PGN files were worse. So I built the app I wanted: open anything, put it on a real board, move the pieces. — Pavel, solo developer Designed for iPhone and iPad.

Review your games with Stockfish 18, as many as you like, and get told in plain English where each one turned. Game review Type your Chess.com or Lichess username and your recent games are there to pick from, or paste a PGN from anywhere. Every move gets a verdict, from best move to blunder, and both players get an accuracy score. The part you will actually use is the coach: after each mistake it says what you missed, what the engine would have played, and why that mattered, in words rather than centipawns. Scrub through the evaluation graph, jump straight to the critical moments, and step through the line the engine wanted on the board. Puzzles Tactics puzzles sorted by rating and theme, with no daily limit. Ask for forks, pins, back rank mates or rook endgames, or let the app choose. The board is made for solving: drag pieces with your thumb, hear them land, and go straight to the next one. Daily challenge Everyone gets the same puzzles each day. Three lives, one attempt, and a streak to protect. Next move Set up any position and Stockfish shows the best move with its top three lines. The engine runs on your phone, so it works with no signal and the position never leaves the device. If the position is in a screenshot from another app or a website, the scanner reads the board off the picture for you. Made to look right Six board colours and ten piece sets, the walnut board by default. A real dark mode that you switch yourself. Move sounds and a soft haptic tick, each with its own switch.
