User studies and expert reviews are established methods for evaluating usability and user experience (UX) in user-centered design. However, practitioners often struggle to integrate these often time-comsuming and costly methods in their design processes. As technological products and services are becoming increasingly mobile, their contexts of use are increasingly diverse and less predictable. While this changing context is hard to capture in lab studies, mobile technologies provide possibilities for new study methods. In this paper we advocate using lightweight mobile tools for crowdsourcing UX feedback. In cooperation with a design agency, we built two apps that allow users to express feedback with text, ratings and picture whenever using a product. The second app assigns feedback to categories. In a case study we compared quantity, relevance, and nature of feedback collected with both UX evaluation apps to traditional evaluation methods. Feedback collected with the apps was considered highly useful by designers and contained more user stories and context than traditional evaluations.
