A beautifully crafted chess clock for iPhone and iPad. Three timing modes, handicap support, and tournament-grade features no other timer offers.
Every feature a chess player needs, nothing they don't.
Sign in with Apple or Google to backup your games to the cloud. Sync across all your devices with offline-first design — games queue locally and upload automatically.
View advanced analytics across all your synced games: win rate, streaks, time control breakdowns, play time trends, and recent activity heatmap.
Scrub through any completed game to see how both clocks looked at every move. Timeline with color-coded pressure markers and auto-playback at 2x–10x speed.
Share a 6-character code so anyone can watch both clocks live from any browser. Perfect for streamers, coaches, and tournament spectators.
Play best-of-3, 5, 7, or 10 match series with running score. Sides alternate each game. Session summary shows per-game results and total time.
Name your players and track rivalries. See win/loss/draw records by opponent, time control breakdowns, streaks, and recent game history.
Create and manage player profiles. Assign players to each side before a game. Stats automatically track performance across all games played.
Every move is timed. After the game, see a full breakdown: per-move bar chart, average think time, longest think, and rushed moves for each player.
The timer watches your tempo. When moves get dramatically faster, a flash indicator appears — turning the clock into something that reads the game.
Choose your clock's voice. Classic wooden click, crisp digital tap, or subtle tournament tone — plus start, low-time warning, and game-end sounds.
Seven visual themes per player. Walnut, Marble, Emerald, Midnight, Rosewood, and two classics. Each player picks their own look independently.
Fischer increment, Bronstein delay, and Simple delay. All three FIDE-recognized timing methods, selectable per game.
Give one player more time with a simple slider. Adjustable from −50% to +50%. Perfect for games between players of different skill levels.
Lock controls during play to prevent accidental taps. Pause requires a long-press with confirmation. Settings remembered across sessions.
Each player gets their own tappable zone. The top clock is rotated 180° so both players can read their time naturally.
Bullet, Blitz, Rapid, and Classical presets included free. Custom time controls with configurable minutes and increment available with Pro.
Per-player resign, draw offer, and checkmate buttons. Move counter, game history, and result tracking all built in.
Optimized for all screen sizes on iOS and Android. Larger fonts and controls on tablets for comfortable tabletop play. Screen stays awake during games.
Feel every move with tactile haptic feedback on clock taps, game actions, and time warnings. Designed for the physical act of playing chess.
From lightning-fast bullet to classical marathon games.
