A team of faculty and students at the University of Minnesota developed the technology that underlies Daynamica - an innovative, research-grade smartphone application collecting and processing highly detailed human activity and travel behavior data with minimal user burden while allowing/enabling Users to view and annotate that data at their convenience. The Daynamica app can be adapted for use in a wide variety of settings and may also be used to deliver personalized, adaptive behavioral interventions. The firm's smartphone application is backed by a suite of secure data storage, processing, and visualization tools - allowing Users to ensure confidentiality and adherence while derive meaning from the data they collect.
