I tried a few rpn apps and this one (the last) is it, has a practical layout and is easy to toggle between modes. Also the "look" is great, similar to Apple's built in calc (keys) - a personal preference.

Great job!!

Don't leave home without it

:
I consider the program of the MOST valuable ones on my iPhone...and wouldn't leave home without it. My wife doesn't understand why I need RPN for routine math, not to mention financial calculations, trig functions and statistics...but I do! When a recent "update" glitch, now resolved, left me without the program for several weeks, I realized how much I missed it, as I found myself trying to open it several times a day. Ultimately, getting it again operative, once I found the instructions on the developer's website, proved ridiculously quick and easy. A particularly nice feature for the Financial section is its nearly automatic generation of a full amortization or depreciation schedule. The one feature I would like to see in the next version would be operation in both the current vertical but also, the horizontal mode, the latter the way one uses the fabled HP11C and HP12C, which I have in the hardwired versions, but which I no longer carry, as allRPNCalc makes them superfluous, rather like a DC-3 in an Airbus 380 era.

5/5 stars
Superb multi-functions with a usable interface.

:
Although I have a different preference in the placement of the keys (I prefer an HP41 layout with the operand keys to the left of the numeric keys) and there is no programmability to this calculator, for what it can do and for the relative ease of being able to do it, I give this app five stars.
