ChoreBuster.net was developed for myself, to remind me what needed doing around the house, and to ensure that everyone I lived with did the same amount.
Today, it has grown into a comprehensive household chore allocation system, that automatically shares out chores in a fair manner. It takes into consideration many special cases, such as holidays, varying personal abilities, busy days and so on.
The development of the chore allocation algorithm and supporting data structures was reasonably challenging. Early versions of the (initially quite crude) algorithm fitted on a single printed A4 page, but at present it would consume approximately 10 pages.
Tens of thousands of households all over the world use this free web site.
Design by someone else but I paid them for it so I get all the credit. 🙂
