Chess Timer is a simple dual timer for over-the-board chess and other two player games. Place you phone flat on the table beside the chess board. Only one clock runs at a time. Tapping the clock face stops one clock and starts the other players clock. Can be used with other competitive two-player board game such as Scrabble, shogi or go. Pro Features: Extra time can be added every turn in one of three ways: Fischer, Bronstein, or a simple delay. Fischer: Time is added to the clock at the end of each turn. Bronstein: Time is added to the clock at the end of each turn, but never more than the turn time. E.g. if the increment is 10 seconds, but the player only takes only 6 seconds on their turn, then 6 seconds is added to the clock. Simple delay: A simple delay before the clock starts each turn. Overtime: An overtime limit can be allowed for each player and penalty points are given for the amount of overtime used. This can be used, for example, as a Scrabble clock.
