Like having an HP calculator on my MacBook Air

I use PCacl on my iPhone and my MacBook Air. It is like having my trusty HP-12C or HP-41CV (which have been in in use since the 80’s), just a little more convenient since those calculators are kept on my desk and don’t travel with me. I have been using PCalc for a couple of years now, and it just keeps getting better. I recommend it for those of you who think in RPN. I’ve thought in RPN since the late 70’s and just can’t use a regular calculator (physical or on the computer). Get it now!
