GODOG — Go Game Clock & Timer

GODOG is a pro-grade game clock and byo-yomi timer built for the game of Go. Use one phone or link two: a single phone starts a game instantly; two phones connect directly via QR code, each player facing their own clock — just like a real game table. 【Time Systems】 ・Japanese byo-yomi: set main time, byo-yomi seconds and periods freely ・Fischer increment: adds time after every move — also great for chess ・Voice countdown reads out the seconds, so your ears know when time is short ・Automatic timeout judgment, calibrated to the millisecond on real devices 【One-Phone Mode】 One phone as the clock; Black and White each tap their own side. 【Two-Phone Mode】 Link two phones via Wi-Fi or personal hotspot (QR pairing). No server involved — no internet needed during play: ・Watch your own clock; your opponent's time stays in sync ・Disconnection detected automatically, with guided reconnect ・No sign-up, no account, no personal data collected 【Languages】 ・English, 日本語, 한국어, 繁體中文, 简体中文 ・Fully localized interface, tutorial, and voice countdown ・Automatically matches your system language on first launch 【Design】 ・Dark theme, with optional full-screen immersive mode during play ・Pause / resume / resign / draw, and one-tap rematch after a game 【Pricing】 Free to download and use. One-phone byo-yomi is completely free. Two-phone mode and Fischer increment use points (earn them by watching ads — stock up in advance), or upgrade to Pro with a one-time purchase: all ads removed, every feature unlocked forever, free restore on a new device.
