The Johns Hopkins Prodensity mobile app provides resources for a safe return to campus. The app will help you follow Johns Hopkins guidelines to keep the community safe through health checks, access to important resources, density monitoring, and alerts.

The app allows participants to access campus and contribute to the health of the community by completing a health check every 12 hours. Completion of the health check (with no symptoms or exposure) and other checklist requirements displays a mobile Campus Pass that allows you to access and remain on campus.
A resources section provides quick access to important websites, phone numbers, and other tools for navigating campus.

Participants who are assigned to spaces (e.g., labs) can also use the app to monitor density and check in and out of spaces.

Please note: this app is currently available to faculty, students, staff, and affiliates at Johns Hopkins campuses.
