Chess Clock Deluxe mimics the function of a traditional chess clock and includes some special features. The app provides two separate timer functions. When one timer is started the other timer is stopped.

Tap the gear icon to activate the timer settings. A standard chess match is 30 minutes, but any time can be set using the up and down arrows.

Speech and sound can be controlled by tapping these icons.

Tap the pause/run icon to pause or restart the clock function.
