### 4/5 — まさに普通

*2026-07-05*

これほど有り難い事はない。仕事柄M+ M−は必要でこれの有るお陰で計算機持ち歩かなくてすむようになった。ただMRCを表示しなくても消せる御破算(リセット)ボタンが利益率の上に有れば評価5です

### 5/5 — Easy to use

*2026-06-20*

Very easy

### 5/5 — Best one in the market, worth the money!

*2026-04-07*

As an accountant I definitely recommend this calculator to everyone. 

This has a double-zero button (along with single zero) and memory functions and bunch of themes if the standard looks boring!

### 2/5 — Gottchaware?

*2026-02-12*

Pop-up ads with screeching alarms, followed by a warning that your phone has been hacked and prompting you to download a repair program. Sketchy at best. App itself is basic but useful with both a memory and history function.

### 1/5 — Be careful:  Porn

*2026-02-02*

The first advert that came up was naked women

### 5/5 — Simple Calculator

*2026-01-01*

Does exactly what the title suggests. Good for the elderly who have difficulty using modern machines.

### 1/5 — Hidden porn

*2025-11-27*

Beware this app has hidden pornographic pictures now in the advertising bar 😢I have been using for a while but recently these images have been appearing. 
I ha e now deleted the app

**Developer response:** Sorry to hear. We have no control of the ads as it is provided by Google. You can report the ads by pressing the ⓘsymbol on the ads. Our team will also monitor this.

### 5/5 — いいねー！

いつもの電卓
