Grandmaster Chess Clock is the chess clock that remembers your games. It is a precise, tournament-grade chess timer for over-the-board play — and the only clock that automatically keeps a record of every game you play on it, shows you where your time went, and replays the moves for you. Play with any time control, record your moves while the clock runs, and leave every board game with a saved score sheet, head-to-head statistics, and an automatic verdict on how you spent your clock. A CLOCK YOU CAN TRUST • Fischer increment, Bronstein, and US delay timing, implemented faithfully • Blitz, bullet, rapid, and classical presets, plus fully custom time controls • Base time to the exact minute and second, per player — time odds included • The screen never sleeps while the clock is running • Portrait table mode and landscape side-by-side layout, readable from both seats • Crisp tap sounds, haptic feedback, and low-time alerts with a color-blind-friendly mode • Pause, resume, and adjust either clock mid-game TWELVE HANDCRAFTED CLOCK FACES Make the clock yours: Digital, Daylight (bold type for bright rooms), Arbiter (the tournament hall standard), Walnut (wood and brass club clock), Pixel (8-bit voxel world), Ember (dark-fantasy fire), Terminal (phosphor CRT), Neon (synthwave dusk), Royal (gold on lacquer), Cosmos (deep-space starfield), Zen (ink and ivory) and Hero (comic-book energy). Digital, Daylight and Arbiter are free. Each face restyles the whole clock screen. RECORD MOVES WHILE YOU PLAY Open the built-in chess board and enter moves as the game happens: a legal move presses the clock automatically, so notation and timekeeping become one action. The board stays fixed, each player sees their own pieces upright from their side of the table, and every move is validated against the rules of chess. A CLOCK THAT REMEMBERS Every finished game is saved automatically to your game diary — players, result, time control, and the full per-move clock timeline. Open any game for per-player statistics: moves played, average move time, longest think, time used, and time remaining. If you recorded the moves, watch the whole game replay itself with one tap. YOUR TIME, COACHED — CLOCK PRO Your clock knows exactly how you spend your time — something no online chess site can see for your real board games. Clock Pro turns that data into coaching: • An automatic time verdict after every game: did you flag, scramble, or manage your clock cleanly? • Time Coach: your time-trouble patterns across weeks and months • Head-to-head records against every opponent, and your score in every opening • An activity calendar of your playing life and personal time budgets • All nine premium clock faces, voice announcements, and no ads SHARE AND EXPORT • Share any game as a report that replays in any browser — board, clocks, move times • Open a game directly in Lichess for free engine analysis • Clock Pro: export your archive as a shareable insights report • Back up and restore your entire archive as a portable file PRIVATE BY DESIGN No account. No sign-up. Everything works offline and stays on your device. Your games are yours. COMMON QUESTIONS Is it free? Yes — the full clock, move recording, the game diary, and game-report sharing are free. Clock Pro (subscription or a one-time lifetime unlock) adds the time-coaching suite, premium faces, and removes ads. Does it work offline? Completely. Airplane mode, a basement club, a park bench — no connection needed. Who is it for? Club and tournament players who want a serious chess clock, improvers who want to learn from every game, coaches tracking a student's real time usage, parents timing scholastic chess, and friends playing blitz at a café. What is a game report? One file that opens in any browser and replays your game — board, clocks, and each move's thinking time. Send it to anyone; nothing to install.
