Are you a traveller or a tourist? Where do we draw the line? Or rather, who draws that line? This curatorial role used to be the sole preserve of travel magazines and guidebooks. If you’d done your research before that trip to Thailand after reading those things, you were a traveller. Else, you were a tourist, part of a headless herd looking for good deals and ghar ka khana. However tenuous, that divide still holds true. But as both increasingly turn online for that great tip or cheap flight, how do you sift through all that digital data out there? Enter the travel app. At the touch of a finger, you can now get live currency conversions (XECurrency), choose the cheapest hotel or flight (TripAdvisor), make point-to-point itineraries (Rome2Rio) or speak the local language anywhere you go (DuoLingo). Soon, there’ll also be an app called Access Earth, a sort of TripAdvisor for persons with disability. For now, here’s a list of five travel apps that are changing the way we travel (or, um, tour).
