### 5/5 — Big Calc

*2026-07-29*

Big Calc is beautiful and easy to work:)

### 5/5 — My go to!

*2026-04-29*

Been using for years, pretty much daily. Recommended!

### 5/5 — Love It!!

*2025-11-20*

I am a senior and this makes it so much easier to type! I don’t make as many mistakes.

### 3/5 — Regular

*2025-07-14, version 2.6*

Me gustaba más cuando podrías poner una imagen de fondo ahora es una simple calculadora común y corriente le quitaron lo divertido

### 5/5 — Easy to Read

*2025-03-01*

I like the large numbers on this calculator. However, I prefer a calculator with the memory function. So, I can go back and see previous calculations. Which helps me when I’m doing my budget in my notebook. Yes I use a notebook, I’m old school.

### 1/5 — Works

*2024-05-29*

In landscape and portrait with nice wallpapers and just $15.

### 5/5 — LARGE PRINT IS ESPECIALLY GREAT

*2024-02-09*

Great to be able to obtain a calculator with large print.  That’s what separates it from all the rest.

### 5/5 — Beautifully Basic

*2024-02-05*

This is a simple, basic, beautiful calculator.   Somehow my very basic calculator disappeared after an update on my tablet so I thought I’ll just find it in the app store.   I tried three similar calculators but they were all awkward & frustrating to use.   I finally downloaded this wonderful calculator that is so much more than the original one!    It has several interesting backgrounds as well as solid color backgrounds to choose from.   It also has a unique feature that shows every number and function you have entered prior to your final answer; you can doublecheck everything you have done, exactly like the paper tape on an adding machine.   This suits my needs perfectly.

### 2/5 — Very basic

*2024-01-14*

A very basic calculator with an unattractive interface; overpriced for what you get. Only good things about it are no ads and no in-app purchases.

### 5/5 — The first time I played

*2023-10-08*

Since I am 9 i am getting smarter every time thanks for the calculator app
