### 5/5 — MY IIJ から こちらのAPPに戻りたい！

*2024-10-10*

クーポンコード､電話番号､ICCID を APP を開いた時点で5回線分見れるこのAPPが最高に使い易いと今は感じてます。
MY IIJ にも クーポンスイッチのAPIを利用した以前の様な仕様を復活させて欲しい！

### 5/5 — 抜群に良い！

*2024-10-10*

MY IIJmio と比べ､最高に良かった。
サービスコード､電話番号､ICCID まで一目で確認出来ましたし､APPを開いた時点で5回線分を確認出来た事が最高に良かった。
何故にユーザーフレンドリーと掛け離れた MY IIJmio に移行させるのか理解出来ないです。

### 5/5 — みおぽんアプリありがとうございました。

*2024-10-02*

10年と9ヶ月IIJにお世話になっています。みおぽんアプリが終了したのは一つの節目のように感じ、後継のアプリに引き継ぎをしてより便利なサービスになっているなと思います。シンプルなデザインが好きでしたね。IIJのMVNOながらの安定した通信回線は信用しています。これからも使いたいです。

### 3/5 — To be discontinued

*2024-09-23*

Oh dear, it is announced that the app will stop working on October, but successor of this app is not provided for non-Japaneses users. I have liked this simple app with IIJmio…

Touch IDつきのiPhone だと下部設定ボタンが見切れていて場所を知らないと詰むのが軽微？　とは思いましたけど

ログイン画面の設定に入ると、
戻る事が出来なくなる。
全く使えない。

### 3/5 — メニュー表示を改善して欲しい

*2023-12-17*

画面下部のメニューが消えてしまう事象とスクロール時に画面上部のタイトルバーが画面中央部に移動してしまう事象を改善して欲しいです。

### 1/5 — 最下部のバナー

*2023-10-17, version 7.1.0*

iPhone15 iOS17、0、3
で最下部の設定他のバナーがないのでAPNプロファイルのダウンロードとかもできない

### 2/5 — サポート終わり？

*2023-10-07, version 7.1.0*
