Increment (sec)

How it works

The first tap starts your opponent's clock (usually Black taps first).
After each move, tap your own side. The increment is added to your time.
The clock opens full screen and the screen stays on while it runs. Pause any time with ❚❚.
On iPhone, add JomChess to your Home Screen to hide the browser bars.
Reset and Exit ask for a second tap, so a stray touch can't end the game.
