The Story
“I love your app, but I cannot use it well.” The message is from Marie, in Lyon, and she wrote it in English because your app gave her no other choice. “The dates are strange. You write 12/25/2024, but in France we write 25/12/2024. I almost booked the wrong day.” You open your own app and try to read it the way Marie reads it. Every button says Generate and Share and Archive. The prices are in dollars. The itinerary comes back in English, and Marie’s travel partner speaks none.
Marie isn’t asking for something exotic. She’s asking for the bare minimum: let me use your app in my language, with my date format, with my currency symbol. The kind of thing every app she uses on her phone already does.
This is the internationalization wall. Your app was built for one language, one date format, one way of writing numbers. The moment someone from another country shows up (and they will, because this is a trip planner, and trip planners are inherently global) everything feels broken.
