Customer Reviews

A very useful and handy calculator

I really like this calculator. I use it all the time. It is simple to use. I use the ( ) a lot to do multiplication within a string of numbers I am adding.
It is the best calculator I have found for my use.

Works Fine

I have had this app for over year. I haven't had any problems with it. Occasionally I will start a calculation and an ad will pop up, but it is easy enough to get rid of and continue my calculations.

Great APP !

Keeps your multiple additions in a string so you can see the inputs. Then keeps them as history so you can go look at previous calculations. Only calculator you need.
