### 5/5 — 練習になる

*2025-08-21, version 1.0.3*

暗算の試験前にこのアプリをしたらいい

### 5/5 — すごく良いアプリ

*2025-06-02, version 1.0.3*

正解していたら自動で次の問題に進むので、サクサク進むことができる。
不正解で正解を見た時にテンキーの上下が元に戻る点のみ気になったがそれ以外はすごく使いやすいアプリだと思う。

### 5/5 — 大学受験に差をつける

*2024-12-26, version 1.0.3*

これは良いです。二桁の足し算引き算を暗算する経験がなかなかする機会がないので、計算力は問題の中の一部でしかやれないのでなかなか上達しない。

計算だけを特化して鍛えてくれる。素晴らしい👍

### 5/5 — 暇つぶしに1番！

*2024-11-17, version 1.0.3*

このゲームをしても勉強をサボってる感が出ないので最高です！

### 5/5 — I love this apps

*2023-08-30*

I love this apps because this apps improve my speed in arithmetic… I recommend this apps…. 

The apps supposedly perfect but have one problem:  the fist number in the top always. visible if you have long question

### 4/5 — カウントダウンタイマーが欲しいです。

*2023-06-18, version 1.0.3*

作者さんにコンタクトとれないのでここに書かせてください。

色々探しましたが、カウントダウンタイマー付きのそろばん計算問題集が他に無かったので付けてくださいませんか?
計算問題集としてはこのアプリが一番だと思います。

### 4/5 — 見やすくて使いやすいが…

*2022-11-23, version 1.0.3*

見やすくて大変使いやすいです。
ただ、一つだけ不満な点があります。
見取り算の口数が10となっていますが、表示されません。これはどうすれば見れるようになるのですか？

### 3/5 — 難易度が変更できない

*2022-09-08, version 1.0.2*

すごくシンプルでとても使いやすいと思った。
デフォルトが1桁の計算だったので桁数を増やそうと難易度をタップしたら、画面を少し拡大したように表示されて、画面右隅の方の文字が見切れてしまっている。さらに、左上に表示されるはずの×ボタンも見切れてしまっているので、難易度を変更しても強制終了するしかなくずっと1桁で計算している。。。計算するときは問題なく表示されて×ボタンも押せる。アプリが全く使えない訳ではないけど難易度が変更できないのがちょっと残念。

使用機種はiPhone 11 ProとiPhone 13 miniです

### 3/5 — 不具合？

*2021-06-10, version 1.0.1*

機能はとてもいいけど
問題が白文字でテンキーが黒でボヤけており
大変見づらいです。
改良お願いします。

### 3/5 — キーが電卓、テンキーの配列と逆

*2021-05-12, version 1.0.0*

非常に惜しいアプリです。みとり算も桁数バラバラで設定できるなど素晴らしい設定があるにもかかわらず、数字入力のキー配列が通常と逆。入力の際に変なクセがついてしまう気がして、使用をためらってしまいます…。電卓、PCのテンキーの配列も加えて欲しいです。
