The trip is the shared anchor. Coordination is the core value.

01 / Coordination challenge

Travelling together, yet information stays scattered.

When everyone uses a separate map app and chat thread, agreeing on stops and keeping track of the group becomes difficult.

01

Where is everyone?

A shared location pin only shows where someone was when they sent it.

02

Which stop is next?

The route and planned waypoints get buried across multiple conversations.

03

Who needs a check-in?

A lack of updates doesn't necessarily mean someone has stopped or needs help.

02 / Shared workspace

Centred on the trip.

A shared space bringing members, routes, and chat together. Every stage of the journey shares the same reference point.
