### 5/5 — 無料って、バグってる！

*2025-10-11*

今まで有料のStaccalを気に入って使ってましたが、突然アップルストアから削除されたようです！
そこで、縦スクロールのカレンダーを探しまくって、1番気に入ったのがこちら💁
無料なんて、バグってます！
【唯一のお願い】
今までのカレンダーからの検索機能があればほんとにありがたいです！
課金しても良いです！
よろしくお願いします。

**Developer response:** 嬉しいレビューありがとうございます！！
僕も長年愛用していたStaccalが使えなくなってしまったのがKoyomiを作ろうと思ったきっかけでした。

アプリを開発した当初は検索や予定のコピーなど機能追加していきたいと思っていたのですが、iOS 26の標準カレンダーが縦スクロールに対応したので、正直に言うと自分自身そちらを使うことが増えてしまいました。

でもこちらのレビューを拝見してやる気が出てきたので少しずつ改良していくかもしれません。もし今も引き続き使ってくださっていたら、あまり期待せず気長にお待ちいただければと思います。
