2000円じゃなかった

【追記】
そもそも買った私のこと全く考えてないのが筒抜け

KataGoを使うための総額として本来は3700円なのに2700円と1番目立つところに表記をしていて総額は以前と変わらないですよ。のコメント返しはおかしい

法律違反レベルだし、昔の話しなんてこっちからしたら知らんそんなのとなります。

1000円なので我慢しますけど残念

Response from developer

アプリのご利用ありがとうございます！ また値段の件、申し訳ございません。 年々、アプリ本体価格を値下げして、KataGoを値上げする価格調整をしています。 画像はかなり古いものでした。 総額は3、4年前から変わりませんですのでご容赦ください。 次回、画像更新します。
