The problem with most app reviews is that they're often written by tech geeks who may not know what it's like to be a human. And the problem with the hundred or so travel apps I reviewed is that they're often designed for those same geeks instead of for busy families and professionals who don't have hours to spend with gadgets. So I sought out unique apps - both free and paid, available at the iTunes store or on the Web - that require the least input and perform the simplest tasks. I also highlighted ones that alert travelers to things like when the sun sets, where to find clean bathrooms and, of course, how to shake hands with the opposite sex in Azerbaijan. -- Adam H. Graham
