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.
