Chessboard Position (FEN) and Scoresheet (PGN) Scanner

CheSScan is a chess utility designed to help chess coaches and chess players in their coaching and training work respectively. Two key features of CheSScan are chessboard position (FEN) scanning and tournament scoresheet (PGN) scanning. Both, FEN and PGN scanning, assume standard chess variant. For scoresheet scanning, tournament scoresheets have to be written in Standard Algebraic Notation (SAN). Games can be saved as a Portable Game Notation (PGN) file on the device storage.

The Service

As of current version, following features are supported by CheSScan:

CheSScan is intended to assist its users in not wasting time in entering chess positions or tournament game moves manually and getting down to more productive task of analyzing chess positions or games from tournament scoresheets. In line with the aforementioned intention CheSScan provides a very powerful chess engine (Arasan) to analyze scanned board positions or scanned tournament games quickly. Your games are stored on your device as a PGN file which can be shared via email.
