01 · The problem

Halden Rail's stations were signed for commuters who already knew the way. Tourists and occasional riders missed connections, and the old app needed signal that the tunnels never had.

02 · What we did

We rode every line with a notebook, then built a routing core that runs on the phone with no connection. The interface speaks in platforms and exits, not in maps: turn left, platform 4, two minutes.

missed connections

stations in 11 months

The app went from a two-station pilot to all 38 stations in eleven months. Missed connections reported to the help desk fell by a third.

We already hired them again. They trained our own team to keep it running.
