DiaLog (Diabetic Logbook) is a memo application for all diabetics with a Palm Pilot. It enables you to enter your diabetes-related data quickly and easily and to view them later sorted by date. Additionaly, you can calculate the neccesary amount of insulin you will need, based on the sugar and food you're going to eat.
Astro Info is an astronomical ephemeris/almanac for PalmOS. It displays some basic information useful to stargazers, such as rise, trans, and set times, coordinates, magnitude and phase information for Sun, Moon, and the other 8 planets and stars. It can display a view of the sky (with stars, the Sun, Moon, and planets positioned) at arbitrary times and locations. You can also search for objects based on their names and see where they are.
MathLib is a PalmOS shared library which makes a complete set of IEEE-754 double-precision math functions available to other Palm applications. These functions include all the standard routines normally accessed by including "math.h" on other systems, including trigonometry (with inverse and hyperbolic), logarithms, exponentiation, and miscellaneous helper functions.
UniSorter demonstrates and visualizes some of the standard sorting algorithms used today. It supports QuickSort, QuickSort and Median-of-Three, QuickSort and Median-of-Three and partition visualization, Insertion Sort, Selection Sort, Bubble Sort, Merge Sort, Heap Sort, Shell Sort, Shaker Sort, Straight Radix Sort, and Distribution Counting Sort.
The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
