### 5/5 — Its a calculator...duh

*2015-07-25*

Straight forward calculator. Perfect for day to day tabulation. Unless one is not used to figuring out percentages (i.e. Tips, etc) on their own lol. In other words if you are bad with math then a simple calculator is probably not for you.

The small size of the program under a mega bite is a huge plus. 

Its add free too! Whoohoo

### 4/5 — Quirky but it grows on you.

*2013-02-23*

It took me a while to figure out it was RPN but once I got that part, all I had to do was figure out how to manipulate the operators. 

If you are not RPN literate, you will be frustrated and the calculator may seem impossible to use. However RPN is really worth learning. It's so much faster for complicated chained calculations but this may not be the best platform on which to learn.

I have an HP clone on the iPhone however the keyboard is too small and I make many entry errors. The big benefit of this app is the large keys which makes it much easier for big guys with large hands. 

I can't live without it now.

### 3/5 — Best thing since RPN

*2012-06-30*

Not sure why negative stars, this is the best calculation interface since Reverse Polish Notation created by HP.

A curser and regular backspace button maybe, as the swipe a character back sometimes means Start Over.  

Get used to it!
