JJAY

About this app

JJAY puts everything you need for campus life in one app. Built by a student who got tired of checking five different websites. WHAT'S INSIDE Today: See what's happening right now. Which facilities are open, today's campus events, and upcoming deadlines all in one place. Classes: Browse professors by major and subject. See ratings, difficulty scores, and reviews before you register. No more guessing which section to take. Events: Campus events on a calendar you can actually read. Filter by category, tap for details, and add events to your phone's calendar. Campus: Find buildings, check facility hours, and look up student services. Emergency contacts are always one tap away. FEATURES - Real-time facility status so you know what's open and when it closes - Professor ratings integrated into the class browsing flow - Academic calendar with deadline alerts so you never miss a registration date - Dark mode that actually works - Student services directory with tap-to-call and tap-to-email Built for John Jay College of Criminal Justice students. All campus information is sourced from publicly available resources. Disclaimer: JJAY is an independent student-built app. It is not affiliated with, endorsed by, or maintained by John Jay College of Criminal Justice or CUNY. Always verify important dates and deadlines with the college directly.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
