### 5/5 — Good app

*2023-05-31*

This app is brilliant and easy to use. However, it seems a lot of the characters remain in shinjitai after conversions. To obtain a thorough list of shinjitai-kyujitai pairs, I recommend using the English Wiktionary page as THE source. For each shinjitai kanji, there is always a kyujitai character listed there.

### 4/5 — 見にくい・・・。

*2022-05-29, version 1.2.3*

便利ですよ。
でも、見にくいです。
文字入力と変換後の表示のスペースはこんなに大きいのに、実際の表示はめっちゃ小さいのは何で？
このスペース、無駄でしょ？
折角スペースこんなに大きいんだから、もっと大きく表示して下さいよ。
あと、新字体も旧字体も入力は手書きでできるようにして下さい。
これで★５つ！です。

### 4/5 — 良いか否かだとすれば良好。

*2021-01-07, version 1.2.1*

見やすい旧漢字の一覧表が欲しいです。

### 5/5 — あるものですね。

*2020-10-22, version 1.2.1*

ちゃんと変換されます。旧字体を調べるのが今よりもずっと楽になりました。開発者の方には感謝です。よくある画面に漢字を書き込んで検索する機能が（課金で良いから）ほしいところです。なくても素晴らしいアプリですけど。

### 1/5 — 全く変換されません。

*2020-08-18, version 1.2.0*

文字を入力しconvertを押しても変換されません。
アプリページに掲載されているスクリーンショットの例文ですら変換されませんでした。
殘念です。
