12Calc

It simply makes the original HP12c look like a toy If you open the hood by touching the HP12c icon a new world of options appear Charts Graphs printing tapes Manuals I have no idea as to why Apple nor Mr Ernie Brock the creator of such amazing tool do not make people aware I have never met Mr Brock other than the personal respond he provides to my queries Is so powerful and easy to use that makes me look like a genius in front of my clients I cannot look at any other cellular brand because I cannot have this AppPeriod Thank you Mr Brock Carlos Mirabal                 The Best Financial Tool Ever Created

The 12calc is the best overall rpn calculator I have found the 12 keypad and behavior for simple calculations the worksheets for more involved calculations all the scientific functions for occasional use And most importantly a tape to send print results for later reference                 The best rpn calculator

Absolutely blows the physical HP12 out of the water Faster Better Stronger The calculator itself is a perfect match with some extra features but the real differentiating power is in the spreadsheets that come imbedded with the calculator Also three more very nice features you can see the numbers you entered for NPV type calculations the backspace key and the color of the screen changes upon launching to tell you the app is ready for use I cant believe the price was 6 bucks I would have paid more but didnt have to even better                 Six stars if I could
