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 clearest difference is in-app purchases: WordSteal at none against SmartGo One's 10. WordSteal also leads on rating (5.0 vs 4.8) and iOS requirement (15.0 vs 26.0). SmartGo One's advantage is update cadence (every 8 days vs every 11 months) and ratings volume (2K vs 2). On price, ads and device support there is nothing between them.
