About this app

RpnCalc Financial is the oldest top-rated financial calculator on the Android Market.

It has an interface that users of conventional financial calculators will be completely at home with, but does much more. Calculations are far faster, doing in a fraction of a second what the classic calculator could take minutes to compute.

RpnCalc Financial is a highly versatile full-function programmable financial calculator. It includes math, finance, and statistics functions.

Features include:

* Time value of money (TVM)
* Amortization
* Cash flow analysis: IRR, NPV
* Bond pricing
* Date and interest calculations
* Percentages, markups, percentage of total
* Scientific mode
* Basic (large key) mode
* 20 Memories
* 99 Program steps
* Key click (haptic feedback)
* Continouous memory

Improvements over the classic calculator:

* 16-level stack
* Front four stack elements displayed
* Programs can be saved and restored
* Programs displayed symbolically
* Memories are not sacrificed to make room for program steps

RpnCalc Financial has a sixteen-level stack to hold more data. The front four elements on the stack are visible at all times, making it much easier to keep track of where you are in your calculations.

Calculator programs are stored and displayed symbolicly, making programming much easier. Progams can be stored and retrieved from the sdcard whenever your Android is in file-sharing mode.

If you use or have used a 12C calculator, this will be instantly familiar. It's fast, accurate, & actually has more functions than the old 12C. The developer responded quickly when I had trouble with getting updates, and solved the problem for me. Only wish is for a more easily readable display. Larger or heavier font for both the keys and the display would be helpful for those of us with aging vision. Otherwise, it's a great app, and one that I use daily.

Absolutely love this calculator app. My favorite calculator has always been my embarrassingly old HP 12C, so it's wonderful to have an app that functions like it with the benefit of not having to deal with distracting ads for a reasonable price. I love that I can lock it into portrait layout so I don't have to turn my phone to use. The aesthetics are perfect. It's wonderful to have its functionality in the convenience of my phone, which I always have handy, instead of having to make the choice of using a crappy calculator app or getting up to track down my HP 12C. LOVE IT!

Works exactly like the original HP calculators. Only it's much, much faster. I've now used it for several years. I routinely run programs on it to run net worth etc. The programs run considerably faster than on the HP12C Platinum. Help file is an excellent reminder if you need to jog your memory. Also.I forgot to mention that it has a fantastic scientific calculator as well.
