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

I've tried multiple Go Apps and this is the best one I've found in terms of playing and advancing your skills. The computer automatically adjusts to your skill level and you can use the board to play against other humans if need be too. There's multiple books available and even information on current top players, all in one place. Highly recommend wether you're just getting started or a seasoned player.
A nice upgrade, but could make better use of AI
Sgiraffe
Overall an excellent tool, reasonably priced for the Pro subscription. It’s great to see some integration with a modern Go engine, but I was disappointed it can only be used to play against. It would be a killer feature to have it available when reviewing games or reading books - hopefully this is a future upgrade. Also keeping the old (and very unreliable) method for estimating game scores seems strange when KataGo is available. There are still a few rough edges and dubious design choices (anyone else surprised by a two finger swipe changing to dark mode?) but this is still an essential app for Go enthusiasts.
Elegant and powerful by seasoned expert

Anders Kierulf has been writing Go software for years. The sgf - Smart Go Format - Go file name was his creation. This is beautifully thought out, powerful and comprehensive software. The yearly subscription for the pro version is good value I feel. To be able to readily see a joseki in your game as deployed in a pro game is a super powerful feature. You should at least give this software a try.
Useful go app

Very handy to have built-in katago for post-game review (or for AI suggestions in the pro game collection section). Can easily send sgfs to email, too. The programmer even kindly included a tournament kifu mode that removes the AI button :)
