### 3/5 — いつもありがとうございます。今後に期待を込めて

*2025-12-15*

年会費10,800円ということもあり、コンテンツをたくさん用意してくださっていて、いつも楽しませていただいています。ありがとうございます。
全体的には満足して利用していますが、個人的に少し気になった点があり、今後の参考になればと思い記載させていただきます。

・ファン同士が交流するチャットルームについて
ファン同士の交流よりも、メンバーの発信を中心に楽しみたいと感じることがあります。チャットルームの表示を選択できるなど、利用スタイルに合わせて調整できると嬉しいです。
通知についても詳細に選択できると嬉しいです。

・メンバーからのリプライについて
一部のファンへのリプライが多く見えることがあり、少しだけ気になる場面がありました。メンバーご本人たちは特に意図されていないと思いますが、いろいろな受け取り方をする方がいるかもしれないと感じました。

・ブロック機能について
ブロックしたユーザーに関しては、存在を認識すること自体がないよう、完全にミュートされる仕様だと助かります。視界に入らない設計を希望します。

・レベル・称号・入会日数の表示について
これらの情報は、他のユーザーから見えない、または非表示にできる設定があると、より気楽に楽しめそうだと感じました。

・X（旧Twitter）やInstagramとの連携機能について
現時点では、連携機能の使いどころが少し分かりづらく感じています。今後、活用方法が分かりやすくなると嬉しいです。

いつも素敵なコンテンツをありがとうございます。
これからも楽しく利用させていただきたいと思っています。

**Developer response:** この度はアプリへのご要望を多数いただきありがとうございます。

本日のご案内にて実現のお約束はいたしかねますが、お送りいただいた内容をチーム内で共有し、サービス改善の参考にさせていただきます。

現状至らぬ点もあるかと存じますが、ファンの皆様に魅力的なアプリと感じていただけるよう、スタッフ一同アプリの運用・改善に精一杯取り組んでまいります。

今後とも1DERZを宜しくお願いいたします。

### 5/5 — 最高！

チャットではメンバーの日常も聞けるしファン同士も交流できる
チケットも優先的に買えるので入った方が断然いいです
更新頻度が高い！

**Developer response:** この度はONE OR EIGHT OFFICIAL FANCLUB「1DERZ」にご登録いただきありがとうございます。
