Live demo
Two phones, one fictional trip
A five-day notebook from Kyōto to Hiroshima, shared between Camille and Sacha. You arrive on day 2: tick a step on one side, watch it appear on the other, then ask the assistant for a change.
No account and no personal data. The sandbox is wiped after 20 minutes without activity.
The notebook inside the phones follows the language of the site: changing language starts a new demo.

The fictional trip
Kyōto, Himeji, Miyajima, Hiroshima
Torii as far as the eye can see, a castle, a garden, a shrine on the water: enough for five days, with routes, steps, cards to show and a few preparations.
