Soundwalk

Unconventional neighborhood tours show the way a hip resident sees Paris and New York. Expect to stop anywhere from cafés and museums to falafel shops and indie concert venues. Download a tour of Hasidic Brooklyn—there are separate ones for men and women. And, for those 18 years and older, French actress and model Lou Doillon narrates a story that leads you through the famously seedy Pigalle neighborhood in Paris.

Cost: $5.99. (The free versions include only the first two stops along a tour.)
