The problem
Hartwell Rail carries nine million passengers a year across Jutland. Its old app took eleven taps to sell a ticket and needed a signal to show one, which the tunnel outside Aarhus does not have.
Most people still queued at the machines.
What we built
- The fastest train first. Search opens on today, with the quickest journey at the top and the price beside it.
- A ticket that lives on the phone. Once bought it opens with no signal, and the code is large enough for a gate to read through a cracked screen.
- One design system for every screen. The app, the ticket machines and the platform displays now share their type, colour and icons.
The best ticket app is the one you close after ten seconds.
How it went
Seven people worked on this for half a year, two of them inside Hartwell for the whole time. We released to staff first, then to one line, then to the network. The app sold more than half of all tickets within four months, and two ticket halls have since become waiting rooms.
