Go Byo-Yomi Timer
Go is traditionally timed with main time plus byo-yomi periods. Many casual Go players use delay-style timing — a fixed thinking window each turn before the main clock runs down — and the same engine handles chess, Scrabble and debate timing.
Pick a time control below and tap your side at the end of each turn. For simple delay and full Japanese byo-yomi with multiple periods, the native ChessTimer app adds dedicated Go modes.
Questions
What is byo-yomi in Go?
Byo-yomi is a countdown of one or more fixed time periods that begins once your main time runs out. You must finish each move within a period to keep it; the native ChessTimer app runs full Japanese byo-yomi with multiple periods.
Can I use this timer for chess and Scrabble too?
Yes. The same two-player clock works for chess, Go, Scrabble, draughts and any turn-based game — pick a time control and tap your side to pass the turn.
