The Best iPhone Apps for Travelers

iPhone App: Sit or Squat

Price: Free

It’s like Zagat’s for potty breaks. Charmin sponsors this user-maintained database of where to find the nearest free toilet based on your location. We especially like the photos of the actual john and the piquant review blurbs (“the air freshener is overpowering, which I think is a good thing”). As with the best apps, this one’s useful for everyday life in your home city too.
