The purpose of this app is to increase your productivity in regards to chess related topics.

It scans, edits and analyzes 2D chess board position in 5 basic steps.


Usage instructions:

  1. Take a picture with the option to flip the board - the quality of the picture and the proper positioning of the board in the green square are of major importance.
  2. Automatic cropping and rotating of the picture - needs your final assessment whether the board image is correctly extracted. Possibility for manual board corners correction if necessary.
  3. Automatic matching of pieces - if the pieces set is supported then the matching should successfully recognize the positioning of the pieces.
  4. Edit board - you could edit castling rights, side to move and could correct pieces positions if necessary.
  5. Analyze - start the Bagatur chess engine for analysis by clicking on the computer icon.


The ELO of the Bagatur chess engine is around 3000. It has a unique playing style leading to different games compared to the games of the top chess engines like Stockfish, Komodo, AlphaZero and Leela Chess Zero.

The application is tested with default pieces sets from lichess.org, chess.com and chess24.com as these sites are intensively used by chess players.

It also supports a few pieces of set, commonly used in old books (e.g. Russian).

We believe these could help chess fans to save the human chess history from the old paper books in computer format like PGN and FEN.

If the application does not work well for you as your chess pieces are not yet included, please send us an image, with ALL chess pieces on the initial board, so we could add it to the application.

We need a picture, which has all the 12 different pieces (white and black, pawn, knight, bishop, rook, queen, king).

Our idea is to incrementally enrich the application with abilities to recognize more and more pieces sets as well as to add new features.

We will highly appreciate it if you help us as this process will take some time.


Permissions:

The app uses ACCESS_NETWORK_STATE and INTERNET permsisions, because it shows home ads and they open the default browser on the device, going to one of our other apps' page on the store or on the website of Metatrans Apps. To be more precise, if the other app is available on the store, from which the app is downloaded, then opens the app page of the other app on the same store. If still the app is not available on the store, then opens the app page on our website. The app pages on our website have app demo video on YouTube, so a connection to youtube domain will also be listed in order to visualize the page in the browser. Our website is created by WordPress, so connections to other domains could be opened as well for technical purposes (e.g. downloading text fonts css).

Your feedback and/or review is more than welcome.

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. You might have to add this repo manually there (see the hint on top of the package list for how to do that).
