### 5/5 — Awesome

*2012-04-23, version 1.0*

I've always preferred RPN for doing calculations and this free app is simply awesome for my basic needs. 

If I had the time to reacquaint myself with an HP 41 style app, that would be awesome but this app works just fine on a daily basis.

### 5/5 — Simple, powerful and fun to use

*2011-10-08, version 1.0*

Definitely smart design. Biggest display and the biggest buttons of all HP like - calculators out there…
All hidden functions slide in with a simple click in the display - Simple, powerful and fun to use: 4-5 Stars!

### 5/5 — Loads fast

*2011-09-23, version 1.0*

Shows promise. Support dev and take it for a spin.
