Objective: This paper describes user characteristics, trends in use, and recommendations delivered by the Self-Checker between March 23, 2020, and April 19, 2021, for pursuing appropriate levels of medical care depending on the severity of user symptoms. Methods: User characteristics and trends in completed conversations that resulted in a care message were analyzed. Care messages delivered by the Self-Checker were manually classified into three overarching conversation themes: (1) seek care immediately; (2) take no action, or stay home and self-monitor; and (3) conversation redirected. Trends in 7-day averages of conversations and COVID-19 cases were examined with development and marketing milestones that potentially impacted Self-Checker user engagement. Results: Among 16,718,667 completed conversations, the Self-Checker delivered recommendations for 69.27{\%} (n=11,580,738) of all conversations to ``take no action, or stay home and self-monitor''; 28.8{\%} (n=4,822,138) of conversations to ``seek care immediately''; and 1.89{\%} (n=315,791) of conversations were redirected to other resources without providing any care advice. Among 6.8 million conversations initiated for self-reported sick individuals without life-threatening symptoms, 59.21{\%} resulted in a recommendation to ``take no action, or stay home and self-monitor.'' Nearly all individuals (99.8{\%}) who were not sick were also advised to ``take no action, or stay home and self-monitor.'' Conclusions: The majority of Self-Checker conversations resulted in advice to take no action, or stay home and self-monitor. This guidance may have reduced patient volume on the medical system; however, future studies evaluating patients' satisfaction, intention to follow the care advice received, course of action, and care modality pursued could clarify the impact of the Self-Checker and similar tools during future public health emergencies.
