Agile principles have led to short development cycles with rapid changes in requirements, especially for mobile apps. The success of apps highly depends on their acceptance by the users. However, testing user acceptance is usually costly and timeconsuming. This imposes a conflict between quality and agility. As current verification and validation methods for requirements do not always fit the demands for volatile requirements, we propose the idea of emotional tracking. In this positional paper, we present how the vision of tracking emotions shown by users while interacting with an app might be realized by using 3D sensing cameras in smartphones. We propose a plan for the technical and organizational process of emotional tracking on the user's device and the backend and an experiment setup to link muscular positions to emotions, to preserve user privacy. With emotional tracking, we provide a new method for verification and validation of software requirements. Our method can be used in parallel to development activities and combines quantitative usage data with users' feelings and emotions to get a fast and holistic idea of an app's user acceptance.
