### 5/5 — 愛用させてもらっています

*2022-10-11*

公式からネイティブアプリが出ることはもうなさそうなので、唯一esaに快適に投稿できるアプリです。
(esaにブラウザアクセスで別アプリからペーストすると余計な改行が入って困る……)

### 5/5 — 本家がやる気ない

*2017-11-28*

助かります。

### 4/5 — iPad pro 10.5版希望

*2017-07-15*

とても便利なので、iPad pro 10.5版もリリースお願いします！

### 5/5 — ピーちゃん可愛い

*2016-12-20*

- 記事の削除アクションが煩雑になったの最高です！🎉
- Swift3対応お疲れ様でした🤔
- 編集をしやすいように、Markdownのショートカットを1Writerのように、KeyboardAccessoryViewで出来たら良いなぁ。💪

### 5/5 — ありがたい！

*2016-05-26*

いままでEvernoteにメモして、esaに転記してたりしてましたが、このアプリのおかげで直接書けるようになりました！

### 5/5 — ありがたや！

*2016-05-10*

思い立った時にスマホでさくさくポストできるー！ありがたや！
