The last game clock you'll ever download.
Chess Clock is a dedicated clock for chess, go, shogi and board games. Giant digits you can read from across the table. Every time control that actually exists. No ads, no account, no internet.
TAP ANYWHERE Your whole side of the screen is the button. No hunting for a tiny target while your flag is falling.
EVERY TIME CONTROL • Fischer increment — time added after every move • Bronstein delay — get back what you used, up to the increment • Simple delay — count down only after the delay expires • Japanese byo-yomi — periods that reset each move • Canadian byo-yomi — a block of time for a set number of stones • Hourglass — your time flows to your opponent • Multi-stage controls — "40 moves in 90 minutes, then 30 minutes" • Sudden death, and any combination of the above
BUILT FOR GO AND SHOGI Japanese and Canadian byo-yomi done properly, with period counts, stone counts and an audible countdown for the last five seconds. Most clocks skip this. We started here.
2 TO 6 PLAYERS Rotate in order, reverse direction mid-game, eliminate players who flag and keep playing. Perfect for board game night, not just duels.
PER-PLAYER HANDICAP Give each player a different time control. Ideal for coaching, for teaching kids, and for uneven matchups.
READ IT ACROSS THE TABLE Full-screen digits that scale to your device. A seven-segment LCD theme, a modern condensed theme, and OLED-black themes that won't light up the room.
SOUND AND HAPTICS Two distinct tap tones, so you know who is on move without looking. Low-time warning, byo-yomi ticks, and a falling-flag buzzer. Turn it all off for a silent tournament hall.
MOVE STATISTICS Move counts, time per move, and a game history you can export.
ACCESSIBILITY Dynamic Type, VoiceOver, high-contrast themes and haptic feedback throughout.
HONEST SOFTWARE Free. No ads. No accounts. No tracking. No internet permission. It is a clock — it should just work, on a plane, in a park, in a tournament hall with no signal.
Made for players who take the game seriously enough to want the clock to disappear.
