Your smartphone is a summer-travel toolbox. Here are additional applications - all free and all in Android and Apple versions - for a smoother trip abroad.
Smart Traveler, from the U.S. Department of State, has embassy and consulate contact information, travel warnings for a disturbingly long list of countries, and extensive country-specific information that you will be glad to have on hand.
Smart Traveler is also where travelers can sign up for the department's Smart Traveler Enrollment Program, to let embassies and consulates know you are in-country, the better to respond if you call for help, and to send you alerts of dangers. Consulates, for example can provide names of local doctors and lawyers or spot you a loan if your pocket's picked and you are destitute in a strange land.
