すごくいいです
ずっとやってみたかったそろばん、アプリで手軽にできるなんて最高です。(子供なら昇給とか段とか貰えればさらに良いだろうけど、大人は日常に活かせればそれで十分なので)1000円で全機能使えるならもちろん課金させていただきます。暗算できるようになりたい！
Big hands
Nice app. Fun learning, and practicing, and practice learning! Haven’t mastered the thumb-finger move on my small screen - but maybe I’ll conquer that with a physical abacus my size. ✋🏾
最高
珠算塾以外のそろばんの勉強の方法を探してたところこのアプリが見つかりました。直感的な操作方法で使いやすいです。
Great app to learn
Already learned 1x3-4 multiplication good after about 2 hours
Left-to-Right
Thank you for this app. I would kindly request that you consider fixing the direction of calculation as some of the answer flows move the furthest right column before moving the column nearest to the left, thus calculating right to left instead of left to right. Otherwise please accept my gratitude for your work in helping people to learn this gift to maths around the world.
