This site was built on the same basic design as MSUA and my motivation was to scratch an itch. I simply felt that using a spreadsheet to track my own nutrient intake, weight and such things was just too clumsy. And thus MSCC was born.
Mludd's Simple Calorie Counter, makes for a neat four letter acronym, just like MSUA. Which is fitting since it's built on the MSUA code.
Just like MSUA this application is GPL licensed and can be downloaded and extended by anyone who wants to.
