“Downloadable applications from Apple’s iTunes App Store can turn your iPhone into [an even more] helpful traveling companion. As of this writing (early August, 2008), the App Store’s Travel category includes foreign language translators, currency and weight/measure converters, a smattering of guides to municipal transportation (such as one for London’s Tube), and Frommer’s city guides for New York and San Francisco,” James A. Martin writes for PC World.
“I tested two programs I thought might interest travelers: Urbanspoon, a free restaurant guide/recommendation program, and TravelTracker, a $30 program designed to help you keep tabs on your itineraries, expenses, and such,” Martin writes.
“Worth noting: If you’re traveling internationally, be wary of using any iPhone application that connects to the Internet for information, as roaming charges for data access can be substantial,” Martin writes.
