RPN vs The Task Board

RPN-38 CX is the first photo-realistic simulation of Hewlett-Packard's popular high-end programmable business calculator HP-38C for the iPhone. Produced from 1979 through 1983, it was the "Chive" member of the third-generation HP calculators known as the "Spice" series. While the simulator works like the original calculator, a number of carefully designed extensions make it a lot easier to use. RPN-38 CX is fully compatible with the HP-12C, except for calculations and programs involving Bonds and Depreciation. Features: • Photo-realistic look-and-feel • Programmable (99 steps, program memory not shared with register memory) • Subroutines, flags, loop control, extended conditional branching • Insert and delete steps with automatic address correction • 20 registers, "continuous", with unlimited store/recall arithmetic • Indirect register addressing • Register view • Program listing view • Program library view • Additional functions (nominal and effective interest rate) • Shortcuts for often-used key combinations • Store and retrieve any number of programs • Sharing: e-mail, AirDrop, Dropbox, copy, paste, print • 40 programs pre-installed Calculator functions: • Percentage (%, ∆%, %Total) • Simple and Compound Interest • Optional odd periods (like HP-12) • Nominal/Effective interest rate conversion • Amortization • Discounted Cash Flow Analysis • Net Present Value, Internal Rate of Return • Date and Calendar (actual or 30/360 day basis) • Statistics (mean, weighted mean, standard deviation) • Linear Regression • Additional functions not found on the HP-38: - Subroutines, flags, loop control, random number, Pi, Log, x² and more Details: cuveesoft.ch/rpn38

The Task Board is a brand new visual approach to organizing to do lists and notes. This is where you quickly note down and arrange your day-to-day tasks and easily mark them done. You enter your pending tasks on the "ToDo" tab and swipe-off all the finished ones to the "Done" tab. You can intuitively swipe the items back and forth between the "ToDo" and "Done" tabs. The board gives you a bird's eye view of all the items in one quick glance. It gives you a good idea of how many things are pending and how they're grouped. You can re-group and re-arrange the items as and when you like. The smooth scroll and pan gives you the feel of a frictionless whiteboard that stretches quite a bit with central area in focus. You can move the board around and bring any group of items in focus. You can also search for an item which brings the item in the central area of focus. To import a list of text items from any other app, simply copy it there and paste it to the task board. Similarly to do a backup of all the items on the board, select all, copy and paste it in any other app you like. You can do occasional cleanups by selecting and trashing the items. The undo button is helpful if you accidentally do something unintentionally. The task board works in both landscape and portrait orientations. These are some of the things you can do with this task board: - quick one-touch note taking - unlimited board space - swipe-off between the boards/tabs - easy scroll - smooth move around - search - arrange all - arrange related (group) - select on board - copy from board - paste on board - delete from board - zoom in and out with a pinch gesture - undo Enjoy managing your never ending list of day-to-day tasks.
