One Plus One - Professional scientific and financial calculator. One Plus One has all the features you need: natural calculator input, 80 functions including time value of money (TVM) and number base conversions, 20 memory registers, graffiti input, and double precision accuracy. Extensive documentation is available for reading or download from the Creative Creek site
P41CX - The HP-41CX Emulator is a complete emulation of Hewlett Packard's venerable HP-41CX RPN calculator and it runs on your Palm OS device.
With P41CX you get the full power of the HP-41CX scientific calculator used by professionals for many, many years.
P41CX benchmarks as fast as or faster (depending on the Palm device) than the original calculator
PalmaryCalc from a simple calculator with a user-friendly interface to a scientific with different input methods (including RPN); logical operations, currency conversion, tip and mortgage

PalmPlot - was inspired by the old Casio FX graphing calculators I used to have when I was in college... It lets you:
Evaluate mathematical expressions - well, it is not just a calculator! Supports hyperbolic, logarithmic, exponential, trigonometric functions, variables and affectations, derivatives, integrals and finite sums, etc
PalmRes- PalmRes is a electrical resistor calculator, it allows the user to enter the colors of a 4-band resistor, and displays the corresponding resistance value (in Ohms). It was developed using OnboardC, SrcEdit, and Bird
PDAcalc classic is a general purpose programmable graphing calculator.
No programming is needed for your basic calculations including plotting functions, solving equations for unknown variables etc. No programming experience is needed to write your own scripts
PDAcalc matrix - Use this calculator for your basic and linear algebra calculations. Using matrices allows you to perform far more powerful calculations with less instructions. Instead of using one value at the time use a matrix or vector containing hundreds of values.
Uses same syntax as high-end mathematical programs like matlab
PDServo is a linear math model of a proportional/psuedo derivative control system. This means that the feed forward compensation is proportional and the feedback compensation is both proportional and differential. This is most common in electric motor servos with tachometer as well as potentiometer feedback
