more This looks like the real deal for managing chess databases on iOS. I still have to explore the features, but I already have a few suggestions:1. Add an option to highlight (arrow or squares) the next move in the game. This allows comparing the game move with the engine move without taking your eyes off the board.2. Display on the board 3-4 engine moves during analysis, it’s useful to have a few options of good moves. See ChessTiger as an example.3. This may seem small, but the yellow background for the notation is quite distracting. Change it to gray or make it customizable.4. Again, this may seem small, but the pawns are too big for all piece sets. Consider adding the Alpha piece set for an alternative.Thank you and congratulation, the app has a lot of potential.

This is the best chess database and analysis program for iOS and iPadOS bar none. I also purchased the paid pro version (Chess Studio without the Lite in its name) by the same author that is even better and worth every penny. Once you learn to use it, you will not look back.

• The new version of the Stockfish 18 engine with Neural Network (NNUE) support has been integrated. According to the authors, Stockfish 18 shows a consistent improvement in performance, with an Elo gain of up to 46 points and winning close to 2 times more game pairs than it loses.
• The Unique online Database with over 11 million games is available. In addition to standard browsing, it is possible to perform targeted searches by data or position. The Unique Database will be updated regularly.
• Added the ability to perform searches in a Database based on PGN Tags (Event, Date, White, Black, ECO, Elo, etc.). This section can be accessed from the main menu.
• Diagram Recognition: this feature allows the user to take and/or upload photos of chess diagrams and convert them into PGN format positions. It is also possible to upload images containing multiple chess diagrams.

• A new training feature has been added: the user can load a game from a database and decide whether to move for White or Black without seeing the moves to evaluate his skills. At the end a report will be produced that traces the entire training session. It is possible to use this functionality either by choosing the game to train with or by letting the application decide the game in random mode. To use this functionality, some settings are possible via an appropriate interface. You can access to this functionality from the menu at the top center of the chessboard screen.

In this way it will be possible to search, for example, all the games that have a typical pawn structure regardless of the position of the other pieces.
• Possibility to choose between different layouts of the board on the screen according to the user's needs. For those using Chess Studio on the iPad, this feature allows you to scroll through the moves of a game with a tap on the right or left of the chessboard.
• Possibility of playing online using the Lichess platform. For blind or visually impaired players this feature is fully supported by Voice Over.
• Automatic insertion of engine analysis into games. To enter the analysis, simply touch the engine analysis line. To use this feature you need to activate it in the application settings.

• The new version of the Stockfish 17.1 engine with Neural Network (NNUE) support has been integrated. According to the authors, Stockfish 17.1 shows a consistent improvement in performance, with an Elo gain of up to 20 points and winning close to 2 times more game pairs than it loses.
• Thematic puzzles: In the Training section, more than 4 million puzzles divided by theme, with the option to select your favorite themes.

At the end a report will be produced that traces the entire training session. It is possible to use this functionality either by choosing the game to train with or by letting the application decide the game in random mode. To use this functionality, some settings are possible via an appropriate interface. There are various ways to access this functionality, for example from the menu at the top center of the chessboard screen.

• Possibility to choose between different layouts of the board on the screen according to the user's needs. For those using Chess Studio on the iPad, this feature allows you to scroll through the moves of a game with a tap on the right or left of the chessboard.
• Possibility of playing online using the Lichess platform. For blind or visually impaired players this feature is fully supported by Voice Over.
