And now, use AI to help uncover the opening that will work for you. Puzzles The Chessvis puzzle collection starts with millions of categorized and rated puzzles from Lichess and adds several unique features including: Category and Rating Control Chessvis lets you set both the category and rating of the puzzles you’re challenged with. Want to try easy forks one day and hard multiple move mates the next? Do it! You’ll never be forced to only do puzzles around some hypothetical rating you’ve “earned”. The entire puzzle collection is always available for you. Visualized Puzzles A unique feature of Chessvis is the "Visualized" puzzle. It presents a puzzle showing the diagram from some number of moves before the actual tactic sequence starts. You're told the number of moves to "visualize" and then solve the problem from a board position that only exists in your mind. This is what got Chessvis started and it’s the only app with it. Other Puzzle Collection Features The “no repeat pledge” - with such an extensive puzzle collection, Chessvis is able to make sure you don’t see the same puzzle twice. Want to focus on solving puzzles quickly? Turn on the timer. Going to be away from the internet? Pull puzzles down to your device and work off-line. See your puzzle history. Download the puzzles you’ve done. All that is in Chessvis. Opening Preparation Build your repertoires focusing on the "moves you'll see". Chessvis believes that you need to think about the moves your opponents actually play and not some complex way too deep repertoire designed by a master who doesn't play anything like the way you do. At ever step in the repertoire design process, Chessvis shows you the moves your opponents actually make and highlights ones you need to think about. Then once you've built your repertoire, practice it with daily spaced repetition. Blindfold Chess Play against the computer with "stepping stones" to help ease your way into blindfold chess. Start with all pieces sharing one color then go to two color disks, one shared color disk and then eventually an empty board. Subscribers had the stockfish and Maia chess engines to the free-to-use Komodo engine. Who’s Guarding Whom A deceptively simple visualization exercise that forces you to mentally track piece movements and how they interact. (No other app has this.) Move Following & Static Boards Track a sequence of moves and then update the board to that point. Or memorize a board layout, then recreate it. Start off easy with just a few pieces and work your way up. Analyze Your Games Download your chess.com and lichess.org games for opening analysis. See what you've been playing, what's been played against you and the results. Videos What better way is there than videos to see Chessvis in action? You can watch the videos within the app. They're all kept short and to the point. Chessvis has always had unique tools to visualize the chessboard and win more games. A famous chess coach said: "Don't think about the pieces being exchanged, visualize how the board will look when the pieces are gone". Move a piece and you affect two places. But it's illegal to physically move the piece and see the effects -- you must learn to visualize. Chessvis is designed to help with that process. Download it today.

Chessvis's advantage is update cadence (monthly vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
