The Best iPhone Apps for Travelers

iPhone App: HiConverter

Price: 99¢

The App Store is awash with converter programs for mundane info like temperature and distance. Most are about the same and work fine, provided you need to make density and pressure conversions on the beach in Rio. But this is one of only a few to include all the digits tourists crave: not just currency exchanges based on today’s rates, but also clothing sizes and shoe sizes, making it indispensable for European shopping runs. There’s a tip calculator that takes tax into account and divides the check by the number of people in your party, which obviates the need for that stand-alone App Store perennial, Tipulator.
