### 3/5 — あ

*2025-12-29, version 3.4*

あかさ

### 5/5 — Abacus functions very well - helps train math and numbers fluency

*2025-09-12, version 3.4*

This is a great way to exercise abacus skills. Learning to use an abacus is great brain training; learning a new way to think about numbers and math. It’s also meditative - puts you in the moment.

### 1/5 — おもんな

*2025-08-05, version 3.4*

掛け算とかできないの課金しないと出来ないのおもんなさすぎ

### 5/5 — ありがとう

*2025-03-29, version 3.4*

そろばんの練習になります。

### 2/5 — 課金をしないとほとんどができない

*2025-03-03, version 3.4*

私は今、そろばん８級です。
ですが、アドオンを購入しないと10級以下のができません。(全国珠算教育連盟の場合)
だから、かけ算、わり算、模擬試験のところを無料でやれたらもっといいなと思っています。

### 2/5 — 横向きで使えなくなった

*2025-01-03, version 3.4*

iPhone14ですが横向きで使えなくなり5桁以上が計算出来なくなりました。改善していただけますか？

### 4/5 — 練習問題を級別にして欲しい

*2025-01-01, version 3.4*

ドリルとしてはすごく良いと思います。

しかし、練習問題が桁でしか選べず３桁➗1桁とかできません。何級レベルとかで設定できるともっと良かったです

### 2/5 — 使えない

*2024-08-22, version 3.4*

掛け算と割り算が課金しないと出来ないのがまじで無理

### 3/5 — 問題の質

*2024-08-20, version 3.4*

問題の質が極端に悪い場合がある。

### 5/5 — Simple

*2024-08-12, version 3.4*

This app has everything you need to stay sharp on the go. It’s my favourite Abacus app.
