About this app

The last game clock you'll ever download.

Chess Clock is a dedicated clock for chess, Go, shogi and board games. Giant digits are easy to read across the table, and every time control you need is built in. No ads, no account and no internet required.

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 — the clock starts counting down after the delay expires
• Japanese byo-yomi — periods reset after every move
• Canadian byo-yomi — a block of time for a set number of stones
• Hourglass — your time flows to your opponent
• Multi-stage controls — for example, 40 moves in 90 minutes, then 30 minutes
• Sudden death and custom combinations

BUILT FOR GO AND SHOGI
Japanese and Canadian byo-yomi include period counts, stone counts and an optional audible countdown for the final seconds.

2 TO 6 PLAYERS
Rotate in order, reverse direction during a game, eliminate players who flag and keep playing. Ideal for board game night as well as two-player matches.

PER-PLAYER HANDICAP
Give each player a different time control for coaching, teaching and uneven matchups.

READ IT ACROSS THE TABLE
Full-screen digits scale to your device. Choose from seven-segment LCD, modern condensed and OLED-black themes.

SOUND AND HAPTICS
Distinct tap tones tell you who is on move without looking. Low-time warnings, byo-yomi ticks and a falling-flag buzzer can all be turned off for a silent tournament hall.

MOVE STATISTICS
Review move counts and time per move, and export your game history.

ACCESSIBLE AND PRIVATE
High-contrast themes, screen-reader support and haptic feedback are built in. The app is free, contains no ads, requires no account, performs no tracking and works fully offline.
