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.

復元できない
有料版を使用していましたが、突然無料版になり、復元もできなくなりました。分かりやすく説明がされており、とても気に入っていただけに残念です。
Purchased the app but crashes when restoring
I purchased the app, but after reinstalling it, I’m unable to restore my purchase. When I tap the “Restore Purchase” option, the app freezes, and I can’t access any of the features I’ve paid for.
I’ll update the review if it gets fixed.

過去に有料版を購入したのに…
今日、突然未購入状態でクリアしたレベルもロック🔐状態になりました。アプリを再度インストールしても改善されません。至急、なんとかしてください。お願いします。
購入画面でフリーズします
iPad Pro 12.9 M1ですが、復元画面でフリーズして購入できません。
I love this app! I’ve learned so much
I’m not one to write reviews but I can honestly say that this app is really good. I’ve learned so much from this app and it’s kind of fun learning abacus tbh. I enjoy this app and so will you!
I love this course BUT…..
Lessons 1-6 are simple steps adding one complication at a time. Lesson 7 is a big jump going from 1 digit to two digit addition and subtraction. Adding 10’s complement work to the already practiced 5’s complement work and then expecting a neophyte to keep track of both at the same time. And on top of that making the problems multi step involving 5 transactions at once. Successfully completing lesson 6 does not prepare one for lesson 7. I think lesson 7 should be broken into at least 3 separate lessons. Additionally, waiting until one has done 5 problems before finding out if one is correct is not helpful. I would learn faster if I knew the quality of my work immediately so I could immediately repeat the work and find my problem. Being able to repeat the same problem repeatedly would increase the speed at which I could learn the patterns.

Great app-some critiques
First off, great app. It’s easy, direct, and the price isn’t ridiculous.
If I could suggest, I would ask for the finger movements section to be a bit clearer. If you need someone who speaks English I would get a translator and more visuals of what the fingers do.
I’d also like if addition and subtraction were in separate categories. I feel I learned addition but not subtraction then was stumped on some subtraction movements.

English translation needs work
The practices build on each other nicely, but this was clearly not written in English originally. The translation is rough, almost to the point of unusability: I would only recommend it to people who are comfortable with math already, or who will have someone with them that is comfortable and can figure out the meaning (if you already know the destination, it makes it easier to decipher unclear directions). The timed practices could also use a reset button - if you lose your place you’re not getting back to the starting conditions on your own and you just have to scrap the whole thing

Yes u need to watch you utube
To pick u the correct thumb and index finger motions. You still need to watch YouTube.
おっさん
でも面白く、且つわかりやすく学べます！
興味
暗算に興味があり、このアプリを試したところ使い勝手が良く熱中しています。
Amazing for learning!
this is a great app for learning the abacus, it clearly states how to use it and has tons of free practise exercises. The feedback I have is I wish it enforced correct finger movements more, otherwise its great.
初心者でもわかりやすく900円出して良かったと思えるアプリ！
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😭

Update suggestion
Nice app, but it would be great if you could tap the bead to move instead of sliding it, it’s inconvenient on the phone than a physical abacus. PS if you do I’ll recommend to friends
