4. AI Position Judgment

• Unlike humans, AI does not simply count territory. It judges the position by estimating the strength of ownership.
• Ownership is displayed by the size of squares, allowing you to understand how AI evaluates the position.

5. A New Type of Go Game

• Compete on equal terms with “Opening Game.”
• Even professional players find it difficult to play an even game or one•stone handicap game against KataGo. But what about limiting the game to the opening?
• Within the first 60 moves, choose the first 5 moves and play the opening you want.
• See how AI responds to various openings. Before long, you may find yourself becoming stronger in the opening.

6. AI Recommended Moves and AI Position Judgment in Try Mode and Review

• Beyond simply trying out moves, you can use AI Recommended Moves and AI Position Judgment on either Black’s or White’s turn to understand various possible developments.
• Playing against a good teacher is important in Go, but review is just as important. Since AI Recommended Moves and AI Position Judgment are also available during review, you can study effectively.

Ratings and reviews

I deleted after I downloaded, for two UI reasons I wanted to be able to get an AI review for my games against players. And I wasn't able to see the cost of the micro transactions without giving credit information. I think it is fine to charge for your expenses but clarity in pricing in app is a must if you add these features I will change my review.

Uninstalled immediately. I was looking for some AI to play around with which would make suggested moves (to see for comparison and factor into how it might affect my own play). This app, kinda does that, but it's not automatic. To begin each game costs 400-800 coins, you start with 1700, then have to buy more. For every move you want to see what the AI suggests (it'll show like three options), it costs additional coins. So, if you wanted the AI commentary throughout a single match — 1000s

Nice to see a Katago for Android. Nice UI. Unfortunately, it uses remote servers, which you have to pay for, and it requires an internet connection. An Android phone ought to be strong enough to beat most users with almost immediate play (few seconds per move) so it would be a nice option for free offline play.
