Baduk Cap lets you capture positions on your wooden Go board and easily transfer them to the SGF file format (Smart Game Format) using built-in image recognition. Include game information such as player names, ranks, captured stones, and more. You can copy the SGF file to the clipboard, send it by email, save it to Dropbox, or export it to apps like EasyGo or SmartGo Kifu. Determine the winner and exact score of your game with the scoring function (available as an in-app purchase). Supported rulesets are: Japanese, Chinese, AGA (Area), AGA (Territory), Ing, New Zealand. Because Baduk Cap automatically recognizes corners of arbitrary size, you can capture problems from books and export them to apps like EasyGo, which offer the spaced repetition system as a study tool. Live capture of your game while it is being played is also supported, featuring automatic move recognition and automatic photo capture, or photos triggered via a Bluetooth camera remote. (This feature is available as an in-app purchase.) External cameras and webcams (UVC-compatible) can be used with this feature. Focus fully on the game instead of interrupting your concentration with manual recording. If you wish, you can broadcast your live game to the Mastodon social network. Baduk Cap supports board sizes of 9 x 9, 13 x 13, and 19 x 19, and is optimized for both iPhone and iPad. The following one-year subscriptions are available (Baduk Cap Pro): • Scoring: Determine the winner and exact result of the game (tap the result for an explanation of how it was calculated) • Game recording: Live capture your game with automatic move recognition, automatic photos, or photos triggered by a Bluetooth camera remote. Broadcast to Mastodon is supported. (Includes all features of the Scoring subscription) These subscriptions do not renew automatically. After one year, you will need to manually resubscribe if you wish to continue using the unlocked features. You can also choose the 'Lifetime Pro' subscription, which is paid once and provides access to all app features forever. Each of the Baduk Cap Pro subscriptions also unlocks the following features: • Siri shortcuts: Take a picture of your Go board with a voice command of your choice • Dark mode • Alternate app icons

Go Clock Pro is a focused game clock for over-the-board go. Place the device beside the board, pick a preset, and start a 9x9, 13x13, or 19x19 game in seconds. No setup maze, no ads, no tracking. WHY GO CLOCK PRO - All four go time systems: Japanese byo-yomi, Canadian byo-yomi, Fischer increment, and Absolute. - Asymmetric time controls for handicap and teaching games. Black and white can use different settings. - Multilingual countdown in Chinese, English, Japanese, and Korean, with beep and haptic fallbacks. - Two-sided table layout. Each player reads their own clock from their side of the board. - Mistake-proof controls. Reset and resign require a deliberate long press. - Tournament Lock keeps appearance and voice settings stable during a match. - Offline by design. No accounts, no ads, no tracking, and no network requests. WHAT YOU GET - Built-in presets covering common East Asian byo-yomi, Korea 40s, Western Canadian, and Europe Fischer formats - Custom games with full asymmetric time control - Resume the last game after the app is closed - Four visual themes: Kaya, Slate, Washi, and Tournament - VoiceOver, Larger Text, Reduce Motion, high contrast, and color-independent cues - Built for iPhone. iOS 16 and later. PRICING Go Clock Pro is a one-time $1.99 purchase. No subscription. No in-app purchases. No ads. FOREGROUND USE Go Clock Pro is designed for foreground table use. iOS limits background timers and audio to specific app categories, and game clocks are not one of them. When the app enters background or the screen locks, the game pauses and saves a snapshot. Resume requires you to come back and tap. This is a deliberate trade-off for accuracy: a snapshot you trust beats a background timer you cannot. For best results, place the device flat on the table beside the board, keep the screen on, and keep the app in the foreground.

Verdict
