This app has 3 components:
(1) Adding machine with a ‘tape’ containing up to 24 itmes. You will use this
most often.
(2) Financial Calculator.
(3) Scientific Calculator - both simulate the HP calculators
A 30 day trial is available.

The design goal of this app is to provide visibility of ALL of the data that you have entered. This data is saved so that the next time you use this app, your saved data is visible. it has a “Read Me” file to assist in getting acquainted. It contains 8 pages with the first item on each page being help text’

It uses ‘Reverse Polish Notation’ concept which is “Enter all of your data first - then your calculations.”

It has a touch screen numeric keypad and if a keyboard is attached its
numeric keys are usable. It retains the most recent 12 numeric keyed items for reuse. It supports “Windows” copy/paste for numeric items to and from the stack or 2 column list. This feature facilitates data entry.

The 8 pages support: Annuities, Bonds, Cash flow, Depreciation, Statistics, Proration, Probability and other Math - Trigonometry functions, user defined NAMED values, These values are retained between sessions. Each page has its own help text and messages.
Data is entered into a stack (push) and then retrieved (pop) from the stack for calculations. Data is saved so that it can be reused later.

Two pages use a common 2 column list for Cash Flow and Statistics data entry. The list allows (pop) and (push). It also allows an individual entry to be changed, deleted or inserted.
The other 6 pages use the common stack as their data entry vehicle.
