Apple COVID-19 UI design & app screens

Apple's COVID-19 app, built with the CDC, provided screening, symptom guidance, and trusted public-health information during the pandemic. It was aimed at the general public seeking authoritative answers.

The design exemplifies Apple's calm, accessible system style: clean typographic hierarchy, plain-language question-and-answer flows, and a step-by-step screening tool. It's a solid reference for high-trust informational UX, progressive questionnaires, and presenting sensitive health guidance with clarity and restraint.
