However, it remains unclear how the acceptance and uptake of these apps can be improved. Objective: This study aimed to investigate the coverage of the SwissCovid app and the reasons for its nonuse in Switzerland during a period of increasing incidence of COVID-19 cases. Methods: We collected data between September 28 and October 8, 2020, via a nationwide online panel survey (COVID-19 Social Monitor, N=1511). We examined sociodemographic and behavioral factors associated with app use by using multivariable logistic regression, whereas reasons for app nonuse were analyzed descriptively. Results: Overall, 46.5{\%} (703/1511) of the survey participants reported they used the SwissCovid app, which was an increase from 43.9{\%} (662/1508) reported in the previous study wave conducted in July 2020.
