Put the phone on the table and start the game.

Two halves, one tap

In portrait the halves are stacked, with the upper one facing the opposite player; in landscape they are side by side. A player ends their move by tapping their own half; before the first move, Black starts White's clock.

Time control types

Increment (Fischer), delay (Bronstein), simple delay (US) and hourglass; the time added or held per move is entered in seconds.

Presets and handicap

Presets from 1+0 to 90+30 and a custom time. Players can be given different times (handicap).

Accurate timing

Time is measured as a difference of performance.now(); below 20 seconds, tenths of a second are shown.

Low-time warning

When time runs low, the player's half changes colour and a beep sounds; when time runs out, a clear notice is shown.

Game information

Each player's move count and the duration of the last move are shown; the game can be paused, reset with confirmation and the sides swapped.
