Making sense with sensors: Self-tracking and the temporalities of wellbeing.

Self-tracking devices and apps often measure and provide interpretations of personal data in a rather straightforward way, for instance by visualising the speed and distance of a run or the quality of sleep during night. There is, however, a growing number of devices claiming to support increased wellbeing by extensive data analysis to provide insights and algorithmic advice about unseen and neglected dimensions of our lives, bodies, and experiences. This article engages with two devices of this kind, namely the Moodmetric and the ŌURA which are two recently released 'smart' rings with associated smartphone apps that claim to measure emotions and rest, promote happiness and help users to perform better. Focusing on how certain values, visions and ideas are used to frame and explain the potential functionality of these devices, this article approaches the discursive underpinnings of their design as deeply intertwined with the temporalities of late modernity. Empirically, the article is based on a discourse analysis of blog posts, marketing materials and user guides from the ŌURA and Moodmetric companies along with video recordings of the public appearances and sales pitches of company representatives.
