SmartGo One is the only Go app you’ll need, whether you’re just getting started or already a seasoned player. Learn, play, study, and improve with SmartGo One. Experience the ancient game of Go on your iPhone, iPad, or Mac in a whole new way. Also known as igo (囲碁), wéiqí (围棋), or baduk (바둑), Go begins with an empty board that gradually fills as players surround territory and capture stones. Start with a 9x9 board and move up to 13x13 and 19x19 as your skills grow. SmartGo One adapts to your strength, automatically adjusting handicaps so games remain competitive and enjoyable. And when you’re ready for a serious challenge, the powerful KataGo-based engine delivers strong, rewarding play. But SmartGo One is far more than a way to play Go. Read interactive Go books while replaying the moves they describe to deepen your understanding. Explore a collection of more than 138,000 professional game records spanning both modern and historical masters. Improve your reading and decision-making skills with a growing library of Go problems and tutorials. Want to know how a master would handle a position on your board? SmartGo’s pattern matching technology compares your game with historical pro games and shows how strong players approached similar situations. No matter your level, SmartGo One helps you continue improving. Features include: • 9x9, 11x11, 13x13, and 19x19 board sizes • Powerful KataGo-based engine • Fast and responsive gameplay • Manual or automatic handicap adjustment • Record, annotate, and edit your games • Territory estimator • Hints and move analysis • Undo and replay controls • Tutorial with over 100 problems • Extensive user manual We value your privacy and only collect the minimum information necessary to make our apps work well for you.

Verdict

The call

The clearest difference is price: SmartGo One at Free against Vexed+'s $0.99. SmartGo One also leads on rating (4.8 vs 4.4) and ratings volume (2K vs 5). Vexed+'s advantage is in-app purchases (none vs 10) and review sentiment (100% vs 77%). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

SmartGo One holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: SmartGo One has 2K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Vexed+'s written reviews are positive against 77% of SmartGo One's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Vexed+ ships an update every 3 days, SmartGo One every 8 days. Both last shipped on November 3, 2026.
