## Most critical reviews (3 lowest-rated)

### 4/5 — Clean and Simple

*2016-08-31*

This is a great App. It is well layed out with all 'common' function keys well located. Can't work out how to change the display from Scientific notation but there must be a way. I wish there was an equivalent for iPhone, it would replace the 42Free App that I have at present. Haven't given it a lot of use but so far so good!

### 4/5 — Very good

*2012-09-26, version 1.6.1*

This is the best RPN calculator available in APP Store. Very clean, easy to use and with 5 row stack. This is not 5 stars because I would like the keyboard keys were a little bit smaller and the display a little bit larger (with larger numbers).
If there were a Solver it would be perfect.

### 4/5 — Elegant

*2010-08-11, version 0*

Calculators are a crowded field. This is a very clean, elegant example; I keep it around with PCalc, which has the advantage of running on iPhone and in portrait mode on iPad.

The new color scheme is IMO a small step backward. Could we please have a setting for the original one? Or perhaps a compromise: the new scheme, but color-on-gray for the red & blue keys; they're just a little too up-front.
