I'm traveling in Taiwan for a couple of weeks and would be lost in translation without an app created by the good folks at Pleco. It lets me hold up the phone to Chinese characters on signs, on menus, on doors and suddenly what is inscrutable becomes clear. The app is multifunctioned and also features a handy live dictionary. Type in what you're trying to say and it appears in Chinese, so you can simply hold up your phone and be understood. I found this essential to renting a car which was accomplished only because the clerk and I could communicate by handing our iPhones to each other. Pleco downloadable from App store. Nope, this isn't a paid post. Just a hat tip from a grateful user in transit.
