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.

Ratings and reviews

Best RPN app out there. You have the choice of 3 layouts - basic (really basic), scientific, and of course financial. I've been using this app for years. I recently switched phones, and had difficulties getting the app working on the new phone (forgot to update my last beta version with the free upgrade code). Contacted the developer and receive a free coupon for the most recent version. What more could you wish for from an app and a developer.

I have used other apps and this one by far without question is amazingly the Best overall one that is available. The updates have improved as well. RPN does appear to be confusing and awkward and might seem like it would be easier to stay with the others and what you have been taught. If you truly want to learn anything you have to take an interest in it study it and use it to understand it. Therefore do so with Faulk's RpnCalc Financial Calculator upgrade and you will come to love it as I do!

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.
