### 1/5 — 使い辛い

*2020-06-02*

使い辛い
筆算の答えをかく四角が
画面の上過ぎるのと
枠が小さすぎます
それと答えを入力するところ
説明もなくわかり辛いです

### 4/5 — 無料でこれは素晴らしい

*2019-02-27*

もともと算数嫌いというのもあり、大人になってから筆算のやり方を忘れてしまっていました。このアプリで取り戻すことが出来ました。これがあれば紙の計算ドリル要らずですね。少しは数字に抵抗がなくなってきました。広告は良くありがちな5秒待たされるタイプではなく、画面の下に申し訳程度に表示されるだけなので大変良いです。

不満な点
・問題を開始する時、答えを入力する時のアナウンスが終わるまで操作できないのでその間待たされるのがもどかしい。
・答えを入力する時に出すテンキーがフェードインでふわっと出てくるのでその際も待たされるのが鬱陶しい。
・間違えた問題を正解するまで解かせて欲しい。
無料なので改善は無いかな？とも思いますが、この3つが改善されれば星5つです。

なるべく大きいディスプレイでやることをおすすめします。私はiPad Pro12.9インチにApplePencilでやっています。iPhoneでは小さすぎて難しいと思います。
