As someone who travels almost constantly, I find myself routinely needing taxis or limos in unfamiliar cities. Thankfully, there are quite a few smartphone apps that can be used to arrange for ground transportation. This article lists five such apps.
Before we get started, I want to pass along one bit of advice: It's a good idea to check the geographic service area prior to downloading an app. Many of the apps that are available work only in specific countries or specific cities. I have tried to put together a list of apps that are as versatile as possible, but one does have significant geographic restrictions — although I had a special reason for including it.
