Big Clock
With the ChessUp app you get a killer big clock that auto-toggles between players when a move is made.
How to Enter Big Clock Mode
To enter big clock mode you must be playing a game using the board. It is not supported when playing a game with just the app because it covers the game board on the screen. All you need to do it press the clock button on the playing screen in the bottom right hand corner. A new window will pop up with a nice big clock. The auto clocking feature works in the standard clock/game board view and in the big clock mode.
