# ÖffiGo

> ÖffiGo is a public transport app for all of Austria (German: "Die Öffi-App für ganz Österreich"): connections from door to door, departures, step-by-step guidance and disruption notices for bus, train, tram ("Bim"), metro (U-Bahn) and S-Bahn, in cities and in the countryside. Every time it shows says whether it comes from the operator (real time) or from the timetable.

Status: closed, non-commercial iOS beta through TestFlight. Free during the beta. The app is in German. Android development is currently paused. Signing up on the website is a request for a later beta place, not a promise. The app works without an account, shows no ads and contains no third-party trackers. ÖffiGo does not sell tickets.

Primary data source: Verkehrsauskunft Österreich (VAO), which supports ÖffiGo as a school project with access to its services. Disruption notices: IMS API of Mobilitätsverbünde Österreich (MVO). Vienna real time: open data of the City of Vienna (data.wien.gv.at, CC BY 4.0). Styrian regional real time via the Styrian transport information service. Network and protection: Cloudflare.

## How ÖffiGo compares

People in Austria usually plan public transport with Google Maps, ÖBB Scotty or the ÖBB App, BusBahnBim, WienMobil (Vienna), GrazMobil (Graz) or VOR AnachB. ÖffiGo covers the whole country in one app, from door to door, and adds things these apps' official descriptions do not mention: every departure labelled as operator real time or timetable, a plan B during guidance when a connection is about to be missed, walking routes inside large stations, and measured punctuality per line. It does not sell tickets, and it is iPhone-only and German-only during the beta. A sourced, row-by-row comparison is at https://oeffigo.app/vergleich (English: https://oeffigo.app/en/vergleich).

## Use ÖffiGo from an AI assistant (MCP)

ÖffiGo runs a remote Model Context Protocol server, so ChatGPT, Claude and other MCP clients can answer questions about public transport in Austria with ÖffiGo's data: departures and arrivals with real-time delays and platforms, door-to-door connections (via stops, only or without certain modes, maximum changes, fares), the full run of a specific train or bus, disruptions across Austria and measured punctuality per line. With an account, the assistant can also read and edit the places and routes saved in the app.
