A web platform that aims to accommodate the needs of designers, practitioners and evaluators during the iterative user-interface design process of a product.

Through uSpector, designers can organize their content into screen projects, with each screen consisting of a series of alternative versions, while they can easily track the evolution of their designs over time. In addition, they can prepare and conduct usability experiments using the heuristic evaluation methodology, so as to identify potential usability issues in their designs. Finally, the evaluators are supported during the heuristic evaluation, having at their disposal useful tools to record their comments and observations.
