Baduk Cap lets you capture positions on your wooden Go board and transfer them easily to the SGF file format with its built-in image recognition.
Determine the winner and exact score of your game with the scoring function (this feature is an in-app purchase).
As Baduk Cap supports corners of arbitrary size and recognizes them automatically, you can capture problems from books and export them to apps like EasyGo, that offer the spaced repetition system as a study tool.
Live capture of your game, while it is being played, is also possible with automatic move recognition and automatic photos (this feature is an in-app purchase). Focus fully on the game, instead of spending time and concentration with recording it manually.
Include game information like player names, ranks, captured stones, … and copy the SGF file to the clipboard, send it as an email, save it to Dropbox or export it to apps like EasyGo or SmartGo Kifu.
Baduk Cap supports board sizes 9 x 9, 13 x 13, 19 x 19 and is optimized for 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 and automatic photos (includes all features of the Scoring subscription)

Each of the Baduk Cap Pro subscriptions also unlocks these features:
- Siri shortcuts: Take a picture of your Go board with a voice command of your choice
- Dark mode
- Alternate app icons

The subscriptions do not renew automatically. After one year, if you want to continue using the unlocked features, you need to manually resubscribe.

Top Notch

This app is excellent and fun to use! The software finds the edges of the board pretty well, but just in case that fails it allows you to calibrate the corners and get it accurate. Multiple scoring methods are included too.

The live recording is nice too, and I can’t wait to try that feature with my club games. The game can be exported via e-mail to open in other apps such as PandaNet.

Things to keep in mind: scoring is an extra $1 and live play recording an extra $5. $10 total was ok for me as it performs the tasks as advertised.

Fantastic and should be adopted as the standard

Been using this app for many many years now and is absolutely fantastic! For anyone who is new to Go this app is invaluable as the scoring component is probably the hardest part for someone who didn’t grow up playing. I’ve also used the export SGF function to capture hundreds of go problems to import into other apps.

This is a really neat program! I’ve been using it to help me learn how to score games, and I’ve also recorded my games with it, to create an sgf file for later review!
