Project
Publit
Free, open-source public transport app for iPhone: live departures nearby, trip planning across Europe and every connection on one timeline. No ads, no account, no tracking.
Context
Mainstream transit apps are slow, full of ads and miss real-time data in many cities. Publit builds on Transitous, a community-run routing service for open transit data, and fixes missing feeds upstream so every open app benefits.
Role
Independent project: concept, iOS app, data work.
Methods
SwiftUI (iOS 17), MOTIS 2 API via Transitous, GTFS / GTFS-Realtime, and a Python converter that turns AMTAB Bari JSON into GTFS-RT protobuf and validates it against the static feed.
Status
Prototype v0.1, not on the App Store yet.
Outcome
Working v0.1 with nearby departures, trip planning, route comparison and saved places, plus a real-time converter for Bari city buses prepared for Transitous.
Interface
Prototype renderings of the v0.1 interface with live Transitous data (Munich, October 2026).
