Bus Plus is a UX concept redesign exploring how public transit apps can reduce friction in route planning, ticket purchasing, and real-time navigation for everyday commuters in Belgrade.
The project tackles a real gap - getting from A to B in Belgrade requires at least four separate apps. Bus Plus consolidates everything into one intuitive mobile experience.

Challenge
Public transit apps in Belgrade are fragmented, unintuitive, and incomplete. Users need multiple apps just to check a route, find a schedule, and buy a ticket - none of which work well together or cover the full journey.
The goal was to design a single, unified transit experience that handles route planning, real-time delays, ticket purchasing, and QR scanning - covering the full commuter journey in as few taps as possible.
