Welcome to QuantumSoft


This is the home page of QuantumSoft, the developers of pro Fit.

pro Fit is a Mac OS application for data/function analysis, plotting, and curve fitting. It is used by scientists and engineers to analyze their measurements and the mathematical models they use to describe them.

Scientists or students can define any mathematical function and use it to model their data, finding by linear or nonlinear curve fitting the function parameters that best describe their observations. Moreover, they can use a number of tools for the mathematical and statistical analysis of functions and data sets, and they can produce esthetically pleasing graphical representations for their scientific reports.

This site provides information about pro Fit, the complete pro Fit package for download and purchase, and several user-support material for existing pro Fit users.
