Recently I deleted dozens of travel apps from my iPhone. Many are great. They allowed me to research unfamiliar places, listen to audio tours and turn my photos into postcards. But travel is about tapping the world, not a screen, so I’m ending the year with an app purge. I’ve kept only what I use often. An app didn’t have to be new (most weren’t) to make the cut, but it had to make travel easier or significantly more enjoyable. Below are a dozen that have earned a spot on my smartphone heading into 2016.
