### 1/5 — kintarou 設定に現れません

*2018-02-25*

IPhone Xで購入したのですがキーボード設定にAddNewKeyboadが現れません。どのようにすれば宜しいのでしょうか。購入理由は方向キー左右が欲しかったからですが

### 5/5 — アフターサービスがとっても丁寧です‼️

*2015-09-21*

どのように使うのか、全然分からない私に何度も何度も、丁寧に対応して貰いました。本当にありがとうございました。

### 1/5 — iOS 8.02に対応していない。 記載しろよ！

*2014-09-28*

iPhone６ （iOS 8.02）使えず。
キーボード追加に表示もされず・・・。

ってか、ここの会社 もう無いの？
HPの更新日が 2013年って・・・

こりゃ 修正も望めないかな・・・（笑）

まだ会社存続してたら 早く修正を！

### 3/5 — 使いやすいのですが、

*2013-10-26*

何度並び替えをしても、順番がぐちゃぐちゃになるのを直して欲しい。

### 3/5 — 使い心地はいいのですが…

*2012-03-19*

矢印キーや使い心地は良いのですが、キーボードをしまって表示をすると、何故か本文に酔狂藍さんと勝手に入力されてしまいます。この現象をどうにかして頂きたい…

### 1/5 — Do not buy

*2011-10-24, version 1.7.1*

Waste of money doesn't do what it says. Disappointed :(

### 1/5 — Not worth it

*2011-07-24, version 1.6.1*

I know it is only 0.69p but it should be free and even then you'll be unhappy you purchased it. You cannot use it with e-mail, SMS or twitter, etc. But I was hoping it would be more of an add on for the already installed Japanese keypad on the iPhone. But it only has a few little extras. Sorry but this app is waste of time.

### 3/5 — メモが消える

*2011-04-24*

タイプし易いのでメモアプリとして長いこと使っていますが、今日初めて、過去に書いたメモの中身が消えてタイトルだけ残るという現象が発生しました。本文欄が何も書いていない状態になります。
そしてそのタイトルだけになってしまったメモをもう一度表示させるとメモ自体が消えてしまう。
この現象のせいでこれまで書き溜めた覚え書きやら日記やらが失われてしまいました。

### 5/5 — うっわ…

*2011-04-06*

そもそもの使い方も読まず購入して評価下げてるお馬鹿さんばかりですね…
標準のメーラーだと書いてる途中で保存した時に、地下鉄等電波が不安定な時に保存がうまくいかない事があったりするので重宝してます

### 3/5 — 値段相応

*2010-08-28*

書いたテキストをメールアプリに転送できる。カーソルキーなど、便利なキーはあるが、標準のキーボードを置き換えるわけではないので、メール以外の用途にはあまり向かないことに注意。
