Finanz is your all in one business and finance assistant for the phones of the UIQ3 generation:
it handles classical business and finance calculations, including loans, annuities, compounded growth, margins, discounted cash flows, net present value... and also bond calculations. Calculations are handled in clever templates (19 available), which work like solvers in a spreadsheet and are particularly useful for repeat calculations and "what if" simulations.
it includes a currency converter where 12 currencies are displayed on one single view. You can select the 12 currencies out of a list of more than 100, and display them in the order you want. Exchange rates can be updated directly via an internet connection (disclaimer).
it is a functions calculator with 12 functions, which you can program to do just any mathematical calculation you decide, with one or more variables.
it features a days calculator and a "percentages for dummies" module. A dedicated module helps you calculate the tip on a restaurant bill and share between several guests...
it is also a plain vanilla hand calculator, which can be operated flip open or flip closed (P990i), in standard algebraic mode or in RPN mode (Reverse Polish Notation).
