月額じゃなく買い切りと言うのが非常に良かったです！ 計算が苦手な人こそやって損はなしだと思います🌸 開発者さん良いアプリをありがとうございます😭

Abacus Lesson Reviews
外出先でも制限なく使いたい
ソロバンを習い始めた小学低学年の娘に使わせたところ、夢中になって使っており、教室の復習や先取り学習にも役立っています。とても優れたアプリです。一つ残念なことに、有料版はWifiなどない外出先では使えないというところですね。
購入したのに未購入
せっかく気に入って、￥900で購入したのに、未購入と表示され、レベルの解除も出来ない。 これじゃあ、詐欺じゃないですか？

暗算トレーニングのデモ動画
購入を考えています。暗算トレーニングのデモ動画がお試しアプリにないので、商品説明ページでデモ動画をアップして欲しいです。

画面の向き
iPadで利用していますが、他の足し算や掛け算のアプリは縦画面一択なのに対し、このアプリは横画面が選択できるので、使いやすくて気持ちよく学習に取り組めています。 ただ、上下方向が一択なのは解せません。このアプリを開くと画面が勝手に逆さまになってしまうのがマイナスポイントです。。
とても分かりやすいが
入門者でも指使いからしっかり学べるようにできている。 1から学べて大変ありがたいのだが、アプリ上でそろばんを弾くのは難しいし、なにより指使いの感覚が身につかない。 出先などで練習する分には良いかもしれないが、やはり実物を使って練習したい。 そこで、答えだけを手入力する機能も追加してほしいと思った。 それなら手元にそろばんを用意して練習できるし、指使いのトレーニングもより実践的にできる。 是非アップデートを検討していただきたい。 (「指の動きトレーニング」というモードはアプリ上で練習するのに特化してるから、実際のそろばんに落とし込むのは難しいとは思う)
固まります
足し算引き算と、かけ算と、割り算とこのシリーズの三つのアプリをダウンロードさせていただきましたが、こちらのアプリは固まってしまってプレイできませんでした。苦笑。 iPhone7です。 機種のせい？
