### 3/5 — 履歴が見にくくなった。

*2026-06-16*

軽いし使いやすいので長年使っていたのですが、スマホを買い替えて再ダウンロードしたら、スマホのサイズのせいかiosのせいか分からないですが、電卓部分と計算式の部分が縦長になって履歴が今までの半分くらいしか見えなくなってしまって残念です。今は文字サイズを小さくしてなんとか使っていますが老眼にはちきついです。
電卓部分の色調整だけでなくサイズ調整または以前のサイズに戻して頂けるとありがたいです。

### 3/5 — 音がしなくなった？

*2025-10-26*

アプリの設定では音ありなのに…

### 3/5 — 少々手間がかかる

*2025-04-30*

アプリ開くと前回の履歴が残ったままなのでリセットする作業が地味にめんどくさいです

### 5/5 — 計算ログが見られて便利

*2024-09-28*

過去に計算した記録が残っているのでとても便利です。

### 5/5 — Excellent Calculator

*2024-08-21, version 6.5.1*

The keys are far more responsive than the iPhone stock calculator. And it records all the calculations I do. Perfect for my bookkeeping.

### 4/5 — 改进

*2024-08-01*

软件做的不错、可以计算税是卖点。但键盘布局希望改进、特别是删除的×、乘号× 很容易按错。数字键太小、不常用的按键太多。建议不常用的按键放到顶部滑动选择、把数字键放大一行一列、让键盘更简洁一些。

### 5/5 — It’s a workhorse

### 4/5 — Good calculator

*2024-01-17, version 6.5.1*

C and AC are very close together and each can be tapped by mistake. 
When the advertising box disappears after paying. May i suggest you increase the buttons size at the bottom half of the screen instead of revealing more of the “tape”
That would make it easier to use. Especially as one can’t increase the button size in the settings. The other thing I’d improve is the equal sound. It is very chirpy, and Annoying, I know you can switch it off, but a nice/classy sound would be a better option. 
Hope these suggestions are taken in board as they would help make the app better. 
Thank you

### 1/5 — 消えるんだ！

*2025-09-29*

計算中、『AC』で、全消えするならわかるけど、『C』を押しても、全消えしてしまったので、沢山、計算の列をつくっていて、途中で打ち間違えたのがあったので『C』を押して、打ち直そうかと思いきや、全消えしてショックでした😱

### 2/5 — Disappointed

*2025-12-30, version 6.6.0*

The calculator works quite well. I’m not at all impressed with the semi-nude AD pictures that occasionally pop up This is ridiculous. Stop doing this!

### 2/5 — NOT an adding machine

*2022-08-23, version 6.4.1*

Disappointed as I thought this works like an adding machine that we use in the accounting world - sometimes also called a printing calculator.  But, this is just a basic calculator. With an adding machine, you can use 10 key and enter things like 5+5- to get 0.  In order words, the operand is entered after the number.  This basic type is just 5+5=10 etc.  If you try 5+5-, you get 10 which is, of course, incorrect.

### 5/5 — My Dream Multi Calculator/Spreadsheet Application

*2024-10-31, version 6.6.0*

Wow, this application makes keeping records of my calculations so easy. It has a place where you can do math equations and then it shows up on a spreadsheet above it. It has a way to remove the individual calculations below and you can swipe the problems from the spreadsheet.
