A chess clock is a two-player timer where each player has their own countdown. After making a move, you tap the clock to switch to your opponent's timer. This ensures both players have equal time and keeps the game moving. While traditionally used for chess, chess clocks work great for Scrabble, Go, and any turn-based game. For group games, try the Turn Timer.
