Voice Chess Play vs Chessmirror

Voice Chess Play is the chessboard that listens. Speak as you would to a playing partner, "Pawn to e4", "Take it with the knight", "Castle kingside", and the move is played on the board. The computer answers, and the game goes on. PLAY BY VOICE • Natural-language commands: "Knight to f3", "The pawn goes to e4", "Take the bishop", "Promote to queen" • Understands spoken coordinates: "f three", "see six", "b four" • When two pieces can make the same move, the app asks which one you mean instead of guessing • Short spoken replies: the opponent's move, check, checkmate, draw • You can always tap the pieces or type the command instead PICK YOUR OPPONENT • Strength from 200 to 3400 Elo with a slider and presets, from beginner to near-maximum engine • Play as White, Black or random • The computer plays sensible moves for the chosen level, never random blunders NEVER LOSE A GAME • Automatic save after every move, even if you close the app or a call comes in • Resume exactly where you left off • History of all your games with date, color, opponent and result SIMPLE AND CLEAR • Large board with easy-to-read letters and numbers on every side • Interface in English and Italian, following your phone's language • No account, no sign-up, no connection needed to play • Full rules: castling, en passant, promotion, stalemate, threefold repetition, fifty-move rule Great for training board visualization, for playing hands-free, or for anyone who finds it more natural to say a move than to drag a piece. Speech recognition uses the system's services. Microphone permission is needed only to hear your moves; the app keeps no audio. Voice Chess Play è software libero (GPLv3).

Chessmirror turns the moves you got wrong into the positions you practise, so the same mistake does not stand in your next game. PHOTOGRAPH A BOARD Point the camera at a real board, a book diagram or a screenshot. Chessmirror reads the position on the device, lets you correct any piece, the side to move and castling rights, and opens it as a game. PLAY WITH NO SLIPS Play against Stockfish 18, built into the app, at a strength you choose. With No Slips on, a move that gives away too much is handed back to you before it is played — and written down, so you meet that position again. A MISTAKE BOOK THAT WRITES ITSELF Every costly move becomes an entry: one position, however many games it turned up in, with what you played and what it cost in winning chances. Import your games from lichess or Chess.com by username, or paste a PGN or FEN, and have every move scored locally. A DAILY THAT KNOWS WHAT IS DUE Practice is scheduled by spaced repetition (FSRS). Each day's queue holds the positions that are due and a few new ones. Play the move, get a plain verdict — passed or not — and play on if you want to. FOUND FOR YOU Mates and tactics the engine found in your own games are collected into sets. Tap the heart on any position to keep it in your favourites. PRIVATE BY DESIGN • Recognition and analysis run on your device. No account, no ads, no tracking. • Games are plain PGN files in your own iCloud Drive, visible in the Files app. • The network is used only when you ask to import games from a chess site. Also: a face-to-face mode for over-the-board play on one phone, an advantage bar, dark mode, iPad layouts, and eight languages — English, Simplified Chinese, Japanese, Korean, French, German, Spanish and Portuguese.
