In the first view controller, this app allows the user to lookup any USCF-registered (United States Chess Federation) players rating. By clicking a cell in the result table, the user will be directed to the USCFs website where the selected players game history and statistics can be seen. In the second view controller, this app allows the user to calculate his/her new rating before it is published (perhaps right after a tournament) by plugging in values that go into the official algorithm. This is a niche product for competitive chess players.
