Within a quick two-week timeframe, ERG developed a mobile-friendly web app to help members of the public search for and identify EPA-approved disinfectants for use against SARS-CoV-2, the virus that causes COVID-19. ERG developed EPA’s List N Tool: COVID-19 Disinfectants using a progressive web app (PWA) design pattern, which provides an installable, app-like experience on desktop and mobile devices delivered directly via the web. Users can search for products based on one or more criteria (e.g., active ingredient, contact time), as well as sort the results and export them to CSV and PDF files as needed. The PWA design that ERG used offers the best of both worlds—the smooth experience of a native app, plus the discoverability and convenience of the mobile web.
