### 5/5 — とても良く考えられたUIです

*2026-08-08*

iステラから乗り換えました。主に観望時に使っています。慣れるのに少し時間がかかりましたがiステラより直感的かつ少ないタップで目的の動作ができるようになった気がします。ARの追従もスムーズな感じで気持ち良いです。

**Developer response:** ご利用ありがとうございます。今後ともご愛用のほどよろしくお願い申し上げます。

### 2/5 — 契約案内画面から戻れない

*2026-08-05*

時刻をちょっといじったりすると、サブスク契約の案内画面が出てきて、戻れなくなり、アプリを強制終了しなきゃならない。そもそもサブスクは好きになれない。
自作ステラトークへの対応が欲しい。対応無いならサブスクの無いiステラで当分様子見。

**Developer response:** ご利用ありがとうございます。有料機能にて表示される契約ご案内画面から戻れない問題についてご不便をおかけしまして申し訳ございません。8/12に修正済みとなっております。ご意見ご要望は承り、今後の開発の検討事項とさせていただきます。
