Chess Clock: OTB Game Timer
A slap-proof two-button chess clock with every time control and a real click.
About Chess Clock: OTB Game Timer
Chess Clock turns your phone into the clock for over-the-board games at home, in the park, at the pub, or on club night. Lay it flat between you and tap your side after each move.
Every slap counts. Each half of the screen is one big button, so a fingertip or a flat palm both register your move.
The press sounds right. One deep, mechanical click on every switch, with a matching haptic, like a real tournament clock.
All the time controls, nothing held back: Bullet, Blitz, Rapid, and Classical presets; Fischer increment, Bronstein, and US delay; custom minutes, seconds, and increment; and a handicap mode with a different time for each player.
Built for the board: the screen stays awake while the clock runs, an interruption pauses the clock instead of eating someone's time, reset is guarded against stray touches, and tenths of a second show under 20s.
No ads. No account. No sign-in. No internet. Pick a time control and play.
