Categories in LifeTopix are organized in the same way that most people organize them in their own mind — hierarchically. For example, the Projects topic has preset categories such as Education, Family, Health + Lifestyle, Hobbies, and Work. The Health + Lifestyle category of Projects contains subcategories such as Health Procedures, Prevention, and Self Improvement. This is a more natural organizational model and allows for greater efficiency.

Categories in LifeTopix are user-customizable via LifeTopix Settings, as well as directly accessible from the topic views that use them.
