Comments on ChessOcr OCR Chess Diagrams - for Android

★★★★★ Impressive & Useful I'm going to pay for the pro key to support this app. I also have a FEATURE REQUEST to be able to scan an eBook that is in PDF format and automatically capture and convert all board diagrams from (start page) to (end page), or (diag x) to (diag y), or (all diagrams) and place the PGN's in one file, as individual "games." Each PGN should identify its diagram number and page number. If possible, combine consecutive board positions into one PGN game. If combined with Asim Pereira's Chess Book Reader, that would be the "perfect storm" of a chess app. Can this be done? (I sent you an email.)
★★★★★ Amazing app Excellent for chess books. Hold phone upright won't work with phone turned horizontally. Great integration to stockfish engine. Thanks a lot for that app.
★★★★★ Super-useful, and works 99% percent for my books. But it would be so _incredible_ useful if there would be a button "Unsuccessful recognition, send image to author" so that the algorithm could be trained with those failed attempts that I get once in a while.
★★☆☆☆ Resolution needs to be real low for recognition to happen. But the board needs to be high contrast. It will not work at all on the standard board used online these days. Even when it does work, it identifies pieces wrong, black as white. And it gives no option to cotlrrect the mistakes. It generates a blank pgn file. The analyse button does nothing. All it does is to share whatever text is there on the clipboard.
★★☆☆☆ Rubbish. Took more time to bring diagram into focus than it would've taken to scribble Forsyth notation on a napkin. Occasionally couldn't recognize diagrams even after finding good focus. When it did recognize, pawns were bishops, some pieces on the wrong squares. Exporting a diagram as picture is a feature more useful than submit to analysis engine. None of the suggested apps would open a position from PGN; I reckon because the feature is broken.
