Customer Reviews

Simple, but too simple

A clear and simple calculator. Unfortunately, it's a little too simple. The fact that it has no memory is the main reason I've replaced it. Even a basic calculator thirty years ago had a memory facility, and this is an essential requirement for even the most basic calculator. Those people giving it five stars simply need to remove their socks to improve their calculating ability to match the benefit this calculator provides.

It is all I need!

Most of the people make life more difficult than what it should be. This app is simple, efficient and easy to use.


If you just want a dead simple calculator then this is for you. No memory so can't do anything other than +,-,x or divide. Absolutely fine for most of my needs
