### 5/5 — 使いやすくて安い

*2026-06-10*

めちゃくちゃ使いやすいです！
そして、毎月のサブスクかと思ったら、買い切りの300円・・・！これは安すぎて有難いです。

### 5/5 — More useful than most calc apps these days

*2025-11-29*

It seems that many calculator apps these days have been infected with PEMDAS equation order of operations. PEMDAS is good for academia, but it isn’t useful in the real world where it is more common to need running totals. With SimpleCalc, you don’t have to worry about equation formulation just to get the answer you need. This app just works.

### 5/5 — めちゃ使いやすい

*2025-04-30*

電卓アプリの中で圧倒的に使いやすいと思います！無料版も良心的でしたが、応援の気持ちも込めて購入！数百円でこれなら安いと思う！

### 5/5 — 5⭐️

*2025-04-28, version 1.9.4*

Nyní už funguje zadávání čísel i přes klávesnici počítače na Macu. Takže plný počet hvězd ⭐️⭐️⭐️⭐️⭐️Skvělá práce a děkuji!!!

PS. Ještě nefunguje desetinná čárka :(

### 2/5 — アンダーバー要らない

*2025-04-13*

アンダーバーが有る意味不明。
デリートキーの位置も不満。何故左横？

**Developer response:** ボタンの下線はアクセシビリティ設定からオフにすることができます

### 5/5 — If you need a business calculator, this is the one

*2025-03-19*

EDIT 19/3/25 within one week of reporting an issue, the developer responded, fixed it, and released version 1.9.2 which is now perfect again.  Once again back in my number one spot.  This should not be called Simple Calulator, it is VERY good, way better than many others and one of the few calculators with tax buttons which are a requirement on any business calculator.  If you need a great business calculator get this one.      	Previous Review of version 1.9.1 - one of the best/nicest designed calculators around. Problem is I use my iPad pro in landscape mode and unfortunately after the update on 3/3/25 the numbers on the keys are now far too big to fit on the actual keys. They still work but it all looks very messy. They are fine in vertical/portrait mode but I don’t use ipad in portrait mode at all.

**Developer response:** Thanks for reporting. Will check and fix it in the next update

### 5/5 — Slide Over時の使いやすさがダントツ

*2025-03-17*

試験勉強でノートアプリを見ながらSlide Overで使用する事が多く、このアプリはSlide Over時でもメモリー機能や√のボタンが配置されているのでとても使い勝手が良い。✖️=で2乗が出来たり、2√で√2の計算が出来るのも、普段使っている電卓と同じで使いやすい。

### 5/5 — 使いやすい

*2025-02-06*

使いやすくて広告なしを購入しました。

### 2/5 — Great calculator

*2024-11-19*

I was not happy with iOS 16. The calculator changed and not in a good way. So I found this one. It’s simple easy to use and perfect for my needs. You get a lot for $1.99!
