## What is SmartGo One?

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

### 3/5 — Play AI Bug

*2026-08-17, version 3.1.6*

There seems to be a bug when selecting to Play AI. Sometimes it works, but more than half of the time, I end up a game where I’m playing both the black and white pieces. I end up having to delete the game and start a new one over and over until the AI finally kicks in. It’s a nice app when it works, but it doesn’t always work as expected.

### 5/5 — Great app

*2026-08-14, version 3.1.6*

Really enjoying playing this with my son

### 5/5 — Superb

*2026-08-10, version 3.1.6*

Simply excellent. SmartGo One is exactly what I needed. Working Go problems has dramatically improved my game.

### 3/5 — Problems not beginner friendly

*2026-08-08, version 3.1.6*

I wanted to use the problems to gain a good foundation as a beginner. The first problem I tried labeled “Elementary” was over my head, had no explanatory tips, and when researched in Gemini AI, said requires reading multiple moves ahead and knowing a tactical concept of crane’s nest tesuji. Things I hope to get to someday, but not where I am now. I see only frustration ahead with the problems in this set for a total beginner.

### 1/5 — Doesn’t work

*2026-08-06, version 3.1.5*

These must be paid reviews the AI/play against computer function dos even work.

### 4/5 — Très bon

*2026-07-15*

Beaucoup d’exercices. Manque juste des explications quand on se trompe

### 5/5 — Excellent Go Resource

*2026-07-11, version 3.1.3*

I love this app for the interactive books. Thank you development team!

### 5/5 — 非常好

*2026-05-07, version 2.8.3*

如题

### 5/5 — Been using for years

*2026-04-03, version 2.8.3*

Such a well written app. Big fan of all of Anders' go projects. Easily the best option for offline play & study on IOS.

### 5/5 — Perfect!

*2026-03-22*

Best go app ever!!!
