Designing for the moment there is no signal
The Offline Survival Kit started as a bug report from a founder stuck at an Athens gate. It is now the feature travelers mention most.

Every travel app is designed on fast office wifi. Real trips happen in airport basements, on the edge of a foreign network, with 4% battery and a boarding pass that will not load.
What we cache
Boarding passes, hotel addresses in the local script, transfer driver contacts, emergency numbers for the country you are in, and the last known state of every booked leg. All of it available with the radio off.
The quiet lesson
The features people thank us for are almost never the clever ones. They are the ones that worked at the worst possible moment.
Design for the airport basement, not the demo stage.
