### 5/5 — 可以说是我下载的众多计算器中最好的一款

*2026-07-23*

多工作表，简单计算和高级计算分开，众多可复制的历史记录，可编辑的算式，非常符合我的需求，强烈期盼开发者能出安卓版的同款计算器

### 5/5 — Класс

*2026-03-27*

Отличный бесплатный калькулятор. Клавиатура удобная, результат видно сразу. Реклама есть, но не мешает. 5 звёзд.

### 1/5 — Publicité galore

*2025-05-23, version 1.65*

C’est pas une calculatrice, c’est une plateforme publicitaire…

### 2/5 — Could be better

*2025-04-26, version 1.65*

Settings has missing parameters. Previous calculations won’t go away from screen.

### 5/5 — Good app

*2025-02-09, version 1.65*

I like that it has heptics. Also that all figures remain in view (not deleted) everytime an action (+,*,etc) is used. It also keeps a history. The only thing that took me awhile to figure out was how to delete history. I had to press and hold on the clock at upper left corner and a drop down menu appeared. Has 3 workstations and very easy to read and use.

### 5/5 — Разделители

*2024-09-24*

Добрый день, приложением абсолютно доволен, но хотелось бы ещё получить вид числа где пробелами разделены 1000, для примера – 1 000 000

### 2/5 — Publicité envahissante

*2024-09-23*

A l’origine la pub était discrète et supportable. Ça devient trop long et plutôt idiot. Dommage car la calculatrice est bien réalisée

### 2/5 — Калькулятор

*2024-06-15*

Всё хорошо, удобно, правильно, если бы не реклама. УБЕРИТЕ РЕКЛАМУ!!!!!!

УБЕРИТЕ РЕКЛАМУ !!!!

### 5/5 — Bewertung

*2024-06-12*

Finde ich saugut. Das ist wirklich mal ein guter Rechner

### 5/5 — TOP!

*2024-05-13*

Ersetzt zum großen Teil meine Tisch Rechenmaschine. Vielen Dank an die Entwickler!!
