I think I've created an neat little all in one application. Check out version 2.4 of Medformula (Free Trial at www.internal-med.org ). Designed primarily for the internist, others may find it useful as well.
This version is a major overhaul from the 1.x series
-Medical Calculator with over 30 formulas
-ABG Analysis with common differentials
-Two-way table statistics (Sens/Spec)
-Pneumonia Severity Index (PORT)
Requirements: Palm OS 3.1+; 340 K free memory and Mathlib (included).
I'm looking for any feedback, especially if any bugs are found.
