Abstract

Along with the smart phone came smart phone applications, which range in functionality, complexity and price. Hugely popular are lifestyle applications which include tools for diet and exercise. Despite the popularity of these applications however, we have yet to see any form of rigorous investigation into their value, i.e. their impact on user behaviour and long term health goals. We embarked on a live clinical trial of a behavior based mobile application designed to assist users on meal replacement diet programs to judge its impact and value. Our analysis showed that users were more engaged with a fully interactive application than an information based application, and that varying analysis conditions seemed to result in varying impact.
