What's New in Chess

4.8.4

July 5, 2026

- IN THIS RELEASE (4.8.4) • Fixed an issue that caused abnormal application behavior in the game data section. • Fixed an issue that occurred when managing the application settings. • Minor bug fixes, general improvements and optimizations. - MAIN FEATURES INTRODUCED IN THE LATEST RELEASES • 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 4 times more game pairs than it loses. • A 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. • From the Help section, you can download the updated full description of the application. The same description can be viewed at the following address: https://chessstudio.wordpress.com/chess-studio/ • Chess Studio is enhanced with a new feature: the ability to browse an Online Database of games organized by Year and Tournament since 1560. This extensive Online Database will be updated daily with new tournaments and games. Access to this database requires a symbolic Premium subscription. • 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. There are various ways to access this functionality, for example from the menu at the top center of the chessboard screen. • Chess Studio can now read databases in ChessBase format. It can import cbh, cbp, cbt, cbg, cba, cbs and cbc formats, thus it is able to interpret the moves of a game, the variations and comments. • 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 function "Search games by material" has been added, through which it is possible to search for games in a database according to the material present on the chessboard. • In the Chess Board screen, you can customize the colors of the top bar, bottom bar, buttons and background. The customization is done in the Settings section. In the opening section is the new functionality to explore the Lichess Master Opening Tree. It is now possible to activate the speech synthesizer to announce the moves made both when entering and when viewing a game. • From the opening section of a database it is possible to save the games relating to a single ECO code or to a single opening variant in a new database. To do this, just swipe left on the opening variant you want to save and follow the directions.

Please add 2cbh format support

This is exactly what I was looking for.

I was previously using Chess Viewer from Everyman, which was not half as good as this one. Also ChessBase mobile app was not very useful for managing pgn’s. This app is very complete with many features and makes it very easy to work on my chess databases. Thanks to the developer, great work!

Good app, but terrible design

Hi! You should make absolutely new universal design for your app.

Restarting iPad fixed problem.

When I first installed this app, and tried to use it, there was a problem saving updated game data, and my original review reflected this. Even after selecting ‘Save Game and Exit’, I would see a warning asking me to confirm if I wanted to exit without saving updated game data. If I exited, and went back into the game, my updates were lost.
However, for some inexplicable reason, restarting my iPad, due to an unrelated problem, has fixed the issue, and the app is now usable.
I’m very happy to be able to update my star rating for an app which is incredibly useful, and great value for the price.
I will re-purchase the app if my original refund request is granted.

Outstanding Chess App!

This is the Swiss Army knife of chess apps! There are so many features built into this app, you’ll just have to explore them all to fully appreciate how much detail has been put into it. It is loaded with settings that allow you to customize the app to your liking. The interface is also very aesthetically pleasing to look at. It excels in PGN database management—which is the primary reason that I use it, including analyzing, annotating, and reviewing both my own games and others from game databases. I purchased both the Chess Studio and Chess Lab apps so that I could move seamlessly between my mobile devices and laptop computer. I was initially looking for a chess app that would work offline and also one where I could adjust the font size of the game moves and annotations. As I use the app, I continue to find that it exceeds my expectations. It is an outstanding value for its broad functionality. I look forward to seeing the amazing refinement that the developer continues putting into this app!
