Currently, chess players have to record moves on their scoresheets and then carefully type them into a computer for computer analysis, after which scoresheets get crumpled and lost—that, or buy a $500 approved digital move recorder to store games digitally and without manual entry. Reine allows you to use a custom scoresheet during a game, take a picture of it after the game, have a PGN (game file) digitally ready for analysis and storage, and toss the paper scoresheet.
