### 5/5 — めちゃくちゃ良い

*2026-03-23*

詰碁と対局、両方ともできて良いです。
詰碁は1000問を軽く超える問題数があり、対局の方も、棋譜保存ができ、AIの棋力も選べます。

とにかく良いです。インストールしてみてください。

### 1/5 — 로그아웃 되는 문제 언제 고쳐요?

*2026-01-11*

초기부터 계속 있던거고 계속 voc가 나오는데 고칠 능력이 있는 사람이 아무도 없나요..?

### 5/5 — Great Tsumego App

*2025-11-26, version 27*

Probably the best freemium Sawhal tsumego app. I wish it had more mode like memorizing Jungseok joseki, and compatibility with macOS (currently blocked).

### 5/5 — 今までの中で一番良い詰碁アプリです。

*2025-11-26*

AIが全部の手に応じてくれる理想の詰碁ソフトです。
こんなアプリを待ってました。

2つ改善要望があります。

一つはお気に入りに入れた問題が何レベルの何番目の問題なのか表示して欲しいです。自分のレベルの自己分析に使えるので。

間違った手を打った時でも自分が打ちたいとこまで打たせてください。
数手打っただけで間違えですと言われて中断されても、なぜ間違えなのか理解できない時があるので。
検討モードでも良いのですが、
解答する前は使えないので不便です。

*2025-07-09*

자꾸 로그아웃이 됩니다.
어플이 가끔 시작을 안됩니다
