## Most critical reviews (4 lowest-rated)

### 4/5 — Excellent for basic RPN use.

*2008-11-26, version 0*

This is a fast, responsive RPN calculator for everyday use.  Just the basic math operations without the clatter of other RPN calculators.  As a result it loads very fast ready for use.  And the vertical orientation, more natural for the iPod touch, is a definite plus.  This is now my default calculator.

My only recommendation is to add a key to empty the entire stack with one keypress, there is room next to the "D" key.  Hopefully in the next update.

Good job!

### 5/5 — Excellent RPN calculator

*2009-04-07, version 0*

I usually dont write reviews, but this is one of the most stable apps i own in the iphone. I bought this app a long time ago but Like others said, it does what it describes very well. Worth the 99 cents very good, nice job.

### 5/5 — Does what it says, and does it well.

*2009-03-01, version 0*

As I summarized in the title, it is a simple, straight forward RPN calculator.  I've been using it for about 5 months now anytime i need a calculator on my phone, and it has held up to anything I have put it through.  For those who don't know how to use RPN calculators, LEARN... It is a very useful way to do math.  Once you know what is going on, you can work far faster, with far less re-inputing numbers.  All in all I think this is a great little app.

### 5/5 — Awesome app

*2008-12-28, version 0*

Love the 4 line display with an additional editing line which essentially turns this into a 5 line display. Can't wait to see future updates and where the developer can take this
