I never write reviews. Ever. But I had to come on here and express how much I love this app. I can only imagine how much time went into this. And I read the little note in the back where you couldn't find a weiqi app you liked so you made it yourself- I really admire that. It really paid off bc this is one of my favorites. So I will give you my idea of what I thought about it. Things that could be improved first and things that are great second, best for last. -The AI could defintely be stronger, I played it on the highest difficulty and it resigned LOL. And im a beginner. -I was going through the games of advanced players and there are some moves where a stone isnt placed on a board, and the "recent move" marking is put on a stone that's already been placed. Idk if thats something im not understanding or if they passed or what. -This is more of a preference, but it would be cool if there were some glossary and explanation section for terms in the rank test. Stuff like "dragons mouth" and "snapback" were given to me and I had to google it. (bc im a noob.). Things I liked!: -The interface is beautiful. I mean sometimes I just sit at the home page and admire the order and tidiness of it. Its so minimalistic, and easy on the eyes, the color scheme is espicially pretty. -4000 years of go. Insane. So you really must've done a WHOLE LOT of research. And it shows just how devoted you are to this game because many people couldnt care less about the history, so I applaud you. Its very compact and straight to the point, each little era. -The lessons are so helpful. This app pretty much is teaching me how to play go at this point. I feel like I learn something new everytime I use it, and I am a huge autodidact and crave learning so its awesome. -Pretty much everything else there is that I havent mentioned. Its all around very nice. Aesthetically, and functionally. So thanks for creating it! : )

It‘s a good app for learning go and play with AI，but AI is not very clever even use Dan difficulty，what‘s AI engine do you use？Another，somepuzzles are not correct.Hope you can read this，and correct these problems.

So far I have only encountered one bug. But it doesn’t let me finish the drills in a section. There is no solution to Throw-in Drill 3. It looks like it’s already solved and I can’t add a stone to any square to pass to drill 4.
