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. Two things most phone clocks get wrong, and this one gets right: EVERY SLAP COUNTS. Each half of the screen is one big button. Hit it with a fingertip or a flat palm, one finger or five, and your move registers. No more pressing twice because the app missed a corner tap. THE PRESS SOUNDS RIGHT. One deep, mechanical click on every switch, with a matching haptic. It is the sound of a real tournament clock, not a thin digital beep. All the time controls, nothing held back: - Bullet, Blitz, Rapid, and Classical presets - Fischer increment, Bronstein, and US delay - Custom minutes, seconds, and increment - Handicap mode, with a different time for each player, so a 10-minute adult can give a 5-minute kid a fair game Built for the board: - The screen stays awake while the clock runs - A phone call or a swipe away pauses the clock instead of eating someone's time - Reset is guarded, so a stray touch cannot wipe a live game - Tenths of a second show under 20s, like a real digital clock No ads. No account. No sign-in. Just anonymous, content-free usage counts to see which features get used. Pick a time control and play.
