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

Verdict

The call

The clearest difference is price: 智子围棋 at Free against Baduk Cap's $3.99. 智子围棋 also leads on in-app purchases (none vs 7) and review sentiment (100% vs 81%). Baduk Cap's advantage is rating (4.7 vs 4.3) and ratings volume (57 vs 4). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Baduk Cap holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Baduk Cap has 57 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 81% of Baduk Cap's written reviews are positive against 100% of 智子围棋's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 1, 2026 and October 27, 2026 respectively.
