Coryat J Scorekeeper is an iPhone utility tool designed for Jeopardy! enthusiasts. Named after two-day Jeopardy! champion Karl Coryat, this app allows users to measure their game performance with a Coryat score. With a user-friendly scoring page and category tracking, you can easily monitor your progress and compare scores.

The app features editable game histories, detailed statistics such as average Coryat and Daily Double performance, and the option to share results on social media. For those seeking more in-depth analysis, an upgrade to Double Coryat provides storage for unlimited games, additional statistics, graphs of scores, clue performance, and the ability to export games into CSV format.
