A trip management app for group travel, with one codebase serving three different views: a subway-map-style Trip Viewer for parents and students, an offline-capable Lead Portal the trip leader updates from the road, and a desktop Trip Manager for building the itinerary ahead of time. Built for a school travel program.

Role-based access — owner, lead, viewer — plus anonymous access by code
Ordered stop itineraries with GPS, scheduled and actual times, and photo galleries
A subway-map-style timeline as the hero visualization for trip progress
Lead Portal designed for offline use and low international data usage
Access codes with rate limiting, expiry and lockout protection
