Q. What is it?
A. Peter's Personal Potent Preferred Pocket PC Processor, or the p-Calculator
Q. What does it do?
A. It is a series of Pocket PC Calculators all rolled into one PocketPC (and if
you register, a copy that works on the Windows desktop (and probably other .NET
1.1 machine) as well!)
A straight forward so called "normal" hand-held style calculator.
But this calculator is anything but normal:
First of all you have 4 separate visable registers that you can
independently calculate numbers for. This means you can keep one number
while temporarily doing a completely different total.
You can always SEE the memory value - it displays in the top bar.
Efficient Memory keys - saves 50% of the keystrokes over every other calculator
You can SEE the pending operation. Normal calculators, if you hit the operation
key (+ etc..,) you are never really sure whether you pressed it because normal
calclators use "negative feedback" systems (in other words - they leave you in
the dark - they tell you nothing). If you hit the key a second time frequently that
is when you realize that you did
press it the first time. But now your totals are messed up - but at least you
know that, if you hadn't hit the key a second time, it would've worked.
Number pad on the right of the screen unlike several I've seen. (This is a good
for right handed people but I admit, it is bad for Lefties. Now, since my wife
and 1 of my 4 children is left handed, you know I will be fixing this
problem up on a future release! I will have a setup where you state leftie or
rightie. - update ... the current version now works for lefties as well as
A RPN calculator
(Reverse Polish Notation) Many engineers and business school graduates swear by
this style, it is much easier to use (once you learn how) than a normal (Polish
Notation to be precise) calculator. If you know what it is you know why you
want it. If you don't do some research on the web. When you are ready to
upgrade - simply switch screens!
A Conversion calculator. Metric, English and all sorts of
Ancient and specialized. Linear, square, cubic, volume, mass, temperature and
What light do you need for situation x, fstop vrs speed changes and much more.
Great for any serious photographers (did I mention I have done professional
photography for more than 20 years? Hmmm, I wonder if that had any bearing on
this being here)
Realestate/Mortgage calculators. Works for US style,
Canadian style and many International style mortgages.
Geometry calculator. (Triangles, Rectangles, Circles
(Useful for some programming including converting HTML color codes between HEX
and Decimal. Includes Octal and Binary calulators for those hard core uses.)
Scientific calculator. All sorts of Electronic, mass and other specialized
functionality coming in future releases.
And yes, I have much more conteplated for future releases. This calculator is
already the best in the world for 80% of calculator users, and I intend on it
being the best for 95%+. I'm not egotistical enough to strive for 100%, I want
an objective that is truly achieveable.
Q. What does it cost?
A. First of all it is shareware, you can use it for 30 days for free. After
that the cost is based on its value to you subject to the registration
minimums. If you like it and pay at least the registration minimum, you are
using it legally.
$5 USD - If all you use is the page with the highly efficient "normal"
$10 USD - if you use one or more of the pages (and don't fall into the rules
$15 USD - if you use the Photographic page but you are only an amateur
$25 if you use the Photographic page and you make money doing photography
$25 if you are in the Real Estate or Banking industry. (Oh, and I've heard all
the excuses why a specific Real Estate Agent shouldn't have to pay the $25
because of blah blah. Do us both a favor if you are tempted to try to convince
me to charge less, just lie to me and pay less - that saves us both time and
effort. Shareware is on the honor system, if you are going to cheat - just do
it and don't waste my time trying to justify your dishonesty. That is just
adding insult to injury. So, if you are a Real Estate agent and you feel the
need to cheat and steal, just do it and don't bug me.)
$20 - all other professional use
Q. What do I get if I pay the registration minimum?
A. A variety of goodies:
The right to use it after day 30 with no guilt!
The right to free upgrades throughout version 2.x and 3.x
A copy of the Windows Desktop version (If you are a Mac or Linux user and you
have .NET 1.1 on your machine, it will probably work for you as well, but I'm
afraid there are no guarantees, I'm a "Windows only" kinda guy. But I really do
appreciate you Mac and Linux guys keeping Microsoft on their toes.)
Q. Why isn't there a link to pick it up right now?
A. It is currently undergoing a major revision to add several of the calculator
pages. I am working on it in my spare time (and I'm a work-a-holic so I truly
don't have a lot of spare time.) I'm having fun using it, if you are interested
in playing with a raw version, contact me and I'll send you a copy to play
with. If you have a corporate reason why you need some of the features quickly,
lets talk a reasonable price to get your needs dealt with quickly and I will
give you a corporate unlimited version (as many users as you want) that will be
valid through version 4.x. Think in the range of $5,000USD. Note that I have
plenty of experience on bringing excellent software products to completion,
both in companies I owned that installed big projects and doing "by the hour"
or "by the project" consulting. I do have the ability to juggle some of my
other projects around for a paid job.
