Over-the-board chess clock

Chess Clock

Open a preset, put the phone between the players, and play. Chess Clock handles fast casual games and the odd controls real players still ask for: delay, Bronstein, byo-yomi, Canadian, and move-count stages.

Chess Clock game screen with large split timers

Open and play

Preset first, custom only when you need it.

No sign-in

Install it and start a clock.

Board-ready

Large tap areas, clear turns, optional lock mode.

At the board

A clock you don't have to explain.

Players need big targets, obvious turns, and controls that stay out of the way once the game starts. That's the whole brief.

Set it and play

Pick a preset, tap Start, and put the phone between the players. Custom setup is there when you need it.

Real time controls

Fischer, Bronstein, US delay, byo-yomi, Canadian, and move-count stages are all supported.

Big targets, clear turns

The active side is obvious from across the board, with sound, haptics, and low-time alerts when you want them.

Your usual clocks

Save the controls you actually use: club blitz, rapid with increment, odds games, and teaching setups.

The flow

From setup to move one without a detour.

Choose a preset for blitz, build a custom control when needed, then leave the screen alone until someone hits their side.
