We are so happy to see the results of HackZürich 2020 right now and thankful that we could contribute to this year’s edition. Especially, our doctoral students Dominik Rüegger with MobileCoach – supported by our MobileCoach Software Engineer Prabhakaran “Prabhu” Santhanam – and Joseph Ollier with the MobileCoach-based intervention Elena+ A Pandemic Lifestyle Care Intervention (www.elena.plus, guest lecture on Elena+) inspired many of the participants of the #17 FROM COUCH POTATO TO FITNESS HERO workshop in collaboration with the CSS health insurance, careum, and the AutoID Lab at ETH Zurich & University of St.Gallen.
